The shortcomings of Aristotelian physics would not be fully corrected until the 17th century work of Galileo Galilei, who was influenced by the late Medieval idea that objects in forced motion carried an innate force of impetus. Galileo constructed an experiment in which stones and cannonballs were both rolled down an incline to disprove the Aristotelian theory of motion early in the 17th century. He showed that the bodies were accelerated by gravity to an extent that was independent of their mass and argued that objects retain their velocity unless acted on by a force, for example friction.
When were the shortcomings of Aristotle's physics overcome? (If the question is unanswerable, say "unanswerable")


Many questions regarding prime numbers remain open, such as Goldbach's conjecture (that every even integer greater than 2 can be expressed as the sum of two primes), and the twin prime conjecture (that there are infinitely many pairs of primes whose difference is 2). Such questions spurred the development of various branches of number theory, focusing on analytic or algebraic aspects of numbers. Primes are used in several routines in information technology, such as public-key cryptography, which makes use of properties such as the difficulty of factoring large numbers into their prime factors. Prime numbers give rise to various generalizations in other mathematical domains, mainly algebra, such as prime elements and prime ideals.
Try to answer this question if possible (otherwise reply "unanswerable"): What is the application of prime numbers used in information technology which utilizes the fact that factoring very large prime numbers is expressed in the sum of two primes?


Warsaw:

The mermaid (syrenka) is Warsaw's symbol and can be found on statues throughout the city and on the city's coat of arms. This imagery has been in use since at least the mid-14th century. The oldest existing armed seal of Warsaw is from the year 1390, consisting of a round seal bordered with the Latin inscription Sigilium Civitatis Varsoviensis (Seal of the city of Warsaw). City records as far back as 1609 document the use of a crude form of a sea monster with a female upper body and holding a sword in its claws. In 1653 the poet Zygmunt Laukowski asks the question:

Read this: Both B cells and T cells carry receptor molecules that recognize specific targets. T cells recognize a "non-self" target, such as a pathogen, only after antigens (small fragments of the pathogen) have been processed and presented in combination with a "self" receptor called a major histocompatibility complex (MHC) molecule. There are two major subtypes of T cells: the killer T cell and the helper T cell. In addition there are regulatory T cells which have a role in modulating immune response. Killer T cells only recognize antigens coupled to Class I MHC molecules, while helper T cells and regulatory T cells only recognize antigens coupled to Class II MHC molecules. These two mechanisms of antigen presentation reflect the different roles of the two types of T cell. A third, minor subtype are the γδ T cells that recognize intact antigens that are not bound to MHC receptors.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): What class of T cells recognizes intact antigens that are not associated with MHC receptors?


It is possible to use a mechanism based on a pistonless rotary engine such as the Wankel engine in place of the cylinders and valve gear of a conventional reciprocating steam engine. Many such engines have been designed, from the time of James Watt to the present day, but relatively few were actually built and even fewer went into quantity production; see link at bottom of article for more details. The major problem is the difficulty of sealing the rotors to make them steam-tight in the face of wear and thermal expansion; the resulting leakage made them very inefficient. Lack of expansive working, or any means of control of the cutoff is also a serious problem with many such designs.[citation needed]

Answer this question, if possible (if impossible, reply "unanswerable"): What development, along with wear, makes it difficult to seal the rotors in an engine that lacks steam?


In September 1958, Bank of America launched a new product called BankAmericard in Fresno. After a troubled gestation during which its creator resigned, BankAmericard went on to become the first successful credit card; that is, a financial instrument that was usable across a large number of merchants and also allowed cardholders to revolve a balance (earlier financial products could do one or the other but not both). In 1976, BankAmericard was renamed and spun off into a separate company known today as Visa Inc.

When a T-cell encounters a foreign pathogen, it extends a vitamin D receptor. This is essentially a signaling device that allows the T-cell to bind to the active form of vitamin D, the steroid hormone calcitriol. T-cells have a symbiotic relationship with vitamin D. Not only does the T-cell extend a vitamin D receptor, in essence asking to bind to the steroid hormone version of vitamin D, calcitriol, but the T-cell expresses the gene CYP27B1, which is the gene responsible for converting the pre-hormone version of vitamin D, calcidiol into the steroid hormone version, calcitriol. Only after binding to calcitriol can T-cells perform their intended function. Other immune system cells that are known to express CYP27B1 and thus activate vitamin D calcidiol, are dendritic cells, keratinocytes and macrophages.

What cell binds to vitamin C?


Read this: Modern primality tests for general numbers n can be divided into two main classes, probabilistic (or "Monte Carlo") and deterministic algorithms. Deterministic algorithms provide a way to tell for sure whether a given number is prime or not. For example, trial division is a deterministic algorithm because, if performed correctly, it will always identify a prime number as prime and a composite number as composite. Probabilistic algorithms are normally faster, but do not completely prove that a number is prime. These tests rely on testing a given number in a partly random way. For example, a given test might pass all the time if applied to a prime number, but pass only with probability p if applied to a composite number. If we repeat the test n times and pass every time, then the probability that our number is composite is 1/(1-p)n, which decreases exponentially with the number of tests, so we can be as sure as we like (though never perfectly sure) that the number is prime. On the other hand, if the test ever fails, then we know that the number is composite.

When using a probabilistic algorithm, how is the probability that the number is composite expressed mathematically?

In 1854 at Ballarat there was an armed rebellion against the government of Victoria by miners protesting against mining taxes (the "Eureka Stockade"). This was crushed by British troops, but the discontents prompted colonial authorities to reform the administration (particularly reducing the hated mining licence fees) and extend the franchise. Within a short time, the Imperial Parliament granted Victoria responsible government with the passage of the Colony of Victoria Act 1855. Some of the leaders of the Eureka rebellion went on to become members of the Victorian Parliament.

The Normans had a profound effect on Irish culture and history after their invasion at Bannow Bay in 1169. Initially the Normans maintained a distinct culture and ethnicity. Yet, with time, they came to be subsumed into Irish culture to the point that it has been said that they became "more Irish than the Irish themselves." The Normans settled mostly in an area in the east of Ireland, later known as the Pale, and also built many fine castles and settlements, including Trim Castle and Dublin Castle. Both cultures intermixed, borrowing from each other's language, culture and outlook. Norman descendants today can be recognised by their surnames. Names such as French, (De) Roche, Devereux, D'Arcy, Treacy and Lacy are particularly common in the southeast of Ireland, especially in the southern part of County Wexford where the first Norman settlements were established. Other Norman names such as Furlong predominate there. Another common Norman-Irish name was Morell (Murrell) derived from the French Norman name Morel. Other names beginning with Fitz (from the Norman for son) indicate Norman ancestry. These included Fitzgerald, FitzGibbons (Gibbons) dynasty, Fitzmaurice. Other families bearing such surnames as Barry (de Barra) and De Búrca (Burke) are also of Norman extraction.

Who did the Irish culture have a profound effect on?

Royal assent: After the bill has been passed, the Presiding Officer submits it to the Monarch for royal assent and it becomes an Act of the Scottish Parliament. However he cannot do so until a 4-week period has elapsed, during which the Law Officers of the Scottish Government or UK Government can refer the bill to the Supreme Court of the United Kingdom for a ruling on whether it is within the powers of the Parliament. Acts of the Scottish Parliament do not begin with a conventional enacting formula. Instead they begin with a phrase that reads: "The Bill for this Act of the Scottish Parliament was passed by the Parliament on [Date] and received royal assent on [Date]".

Imperialism and colonialism both dictate the political and economic advantage over a land and the indigenous populations they control, yet scholars sometimes find it difficult to illustrate the difference between the two. Although imperialism and colonialism focus on the suppression of an other, if colonialism refers to the process of a country taking physical control of another, imperialism refers to the political and monetary dominance, either formally or informally. Colonialism is seen to be the architect deciding how to start dominating areas and then imperialism can be seen as creating the idea behind conquest cooperating with colonialism. Colonialism is when the imperial nation begins a conquest over an area and then eventually is able to rule over the areas the previous nation had controlled. Colonialism's core meaning is the exploitation of the valuable assets and supplies of the nation that was conquered and the conquering nation then gaining the benefits from the spoils of the war. The meaning of imperialism is to create an empire, by conquering the other state's lands and therefore increasing its own dominance. Colonialism is the builder and preserver of the colonial possessions in an area by a population coming from a foreign region. Colonialism can completely change the existing social structure, physical structure and economics of an area; it is not unusual that the characteristics of the conquering peoples are inherited by the conquered indigenous populations.

 Colonialism never means a country doing what?


Computational complexity theory:

Computational complexity theory is a branch of the theory of computation in theoretical computer science that focuses on classifying computational problems according to their inherent difficulty, and relating those classes to each other. A computational problem is understood to be a task that is in principle amenable to being solved by a computer, which is equivalent to stating that the problem may be solved by mechanical application of mathematical steps, such as an algorithm.

Formed in 1946, Sierra Sky Park Airport is a residential airport community born of a unique agreement in transportation law to allow personal aircraft and automobiles to share certain roads. Sierra Sky Park was the first aviation community to be built[citation needed] and there are now numerous such communities across the United States and around the world. Developer William Smilie created the nation's first planned aviation community. Still in operation today, the public use airport provides a unique neighborhood that spawned interest and similar communities nationwide.

The Black Death ravaged much of the Islamic world. Plague was present in at least one location in the Islamic world virtually every year between 1500 and 1850. Plague repeatedly struck the cities of North Africa. Algiers lost 30 to 50 thousand inhabitants to it in 1620–21, and again in 1654–57, 1665, 1691, and 1740–42. Plague remained a major event in Ottoman society until the second quarter of the 19th century. Between 1701 and 1750, thirty-seven larger and smaller epidemics were recorded in Constantinople, and an additional thirty-one between 1751 and 1800. Baghdad has suffered severely from visitations of the plague, and sometimes two-thirds of its population has been wiped out.

The weight of boilers and condensers generally makes the power-to-weight ratio of a steam plant lower than for internal combustion engines. For mobile applications steam has been largely superseded by internal combustion engines or electric motors. However, most electric power is generated using steam turbine plant, so that indirectly the world's industry is still dependent on steam power. Recent concerns about fuel sources and pollution have incited a renewed interest in steam both as a component of cogeneration processes and as a prime mover. This is becoming known as the Advanced Steam movement.[citation needed]

Read this: In general, there are three sectors of construction: buildings, infrastructure and industrial. Building construction is usually further divided into residential and non-residential (commercial/institutional). Infrastructure is often called heavy/highway, heavy civil or heavy engineering. It includes large public works, dams, bridges, highways, water/wastewater and utility distribution. Industrial includes refineries, process chemical, power generation, mills and manufacturing plants. There are other ways to break the industry into sectors or markets.

Loudoun, a capable administrator but a cautious field commander, planned one major operation for 1757: an attack on New France's capital, Quebec. Leaving a sizable force at Fort William Henry to distract Montcalm, he began organizing for the expedition to Quebec. He was then ordered by William Pitt, the Secretary of State responsible for the colonies, to attack Louisbourg first. Beset by delays of all kinds, the expedition was finally ready to sail from Halifax, Nova Scotia in early August. In the meantime French ships had escaped the British blockade of the French coast, and a fleet outnumbering the British one awaited Loudoun at Louisbourg. Faced with this strength, Loudoun returned to New York amid news that a massacre had occurred at Fort William Henry.

Normans came into Scotland, building castles and founding noble families who would provide some future kings, such as Robert the Bruce, as well as founding a considerable number of the Scottish clans. King David I of Scotland, whose elder brother Alexander I had married Sybilla of Normandy, was instrumental in introducing Normans and Norman culture to Scotland, part of the process some scholars call the "Davidian Revolution". Having spent time at the court of Henry I of England (married to David's sister Maud of Scotland), and needing them to wrestle the kingdom from his half-brother Máel Coluim mac Alaxandair, David had to reward many with lands. The process was continued under David's successors, most intensely of all under William the Lion. The Norman-derived feudal system was applied in varying degrees to most of Scotland. Scottish families of the names Bruce, Gray, Ramsay, Fraser, Ogilvie, Montgomery, Sinclair, Pollock, Burnard, Douglas and Gordon to name but a few, and including the later royal House of Stewart, can all be traced back to Norman ancestry.

What did Sybilla of Normandy introduce to Scotland?


In the 1910s, New York–based filmmakers were attracted to Jacksonville's warm climate, exotic locations, excellent rail access, and cheap labor. Over the course of the decade, more than 30 silent film studios were established, earning Jacksonville the title of "Winter Film Capital of the World". However, the emergence of Hollywood as a major film production center ended the city's film industry. One converted movie studio site, Norman Studios, remains in Arlington; It has been converted to the Jacksonville Silent Film Museum at Norman Studios.

Research by Harvard economist Robert Barro, found that there is "little overall relation between income inequality and rates of growth and investment". According to work by Barro in 1999 and 2000, high levels of inequality reduce growth in relatively poor countries but encourage growth in richer countries. A study of Swedish counties between 1960 and 2000 found a positive impact of inequality on growth with lead times of five years or less, but no correlation after ten years. Studies of larger data sets have found no correlations for any fixed lead time, and a negative impact on the duration of growth.

Each year, the southern California area has about 10,000 earthquakes. Nearly all of them are so small that they are not felt. Only several hundred are greater than magnitude 3.0, and only about 15–20 are greater than magnitude 4.0. The magnitude 6.7 1994 Northridge earthquake was particularly destructive, causing a substantial number of deaths, injuries, and structural collapses. It caused the most property damage of any earthquake in U.S. history, estimated at over $20 billion.

The normal force is due to repulsive forces of interaction between atoms at close contact. When their electron clouds overlap, Pauli repulsion (due to fermionic nature of electrons) follows resulting in the force that acts in a direction normal to the surface interface between two objects.:93 The normal force, for example, is responsible for the structural integrity of tables and floors as well as being the force that responds whenever an external force pushes on a solid object. An example of the normal force in action is the impact force on an object crashing into an immobile surface.
Try to answer this question if possible (otherwise reply "unanswerable"): What causes Pauli repulsion?


Rhine:

The length of the Rhine is conventionally measured in "Rhine-kilometers" (Rheinkilometer), a scale introduced in 1939 which runs from the Old Rhine Bridge at Constance (0 km) to Hoek van Holland (1036.20 km). The river length is significantly shortened from the river's natural course due to number of canalisation projects completed in the 19th and 20th century.[note 7] The "total length of the Rhine", to the inclusion of Lake Constance and the Alpine Rhine is more difficult to measure objectively; it was cited as 1,232 kilometres (766 miles) by the Dutch Rijkswaterstaat in 2010.[note 1]

Please answer a question about this article. If the question is unanswerable, say "unanswerable". Where does the Rhine begin?


Some theories developed in the 1970s established possible avenues through which inequality may have a positive effect on economic development. According to a 1955 review, savings by the wealthy, if these increase with inequality, were thought to offset reduced consumer demand. A 2013 report on Nigeria suggests that growth has risen with increased income inequality. Some theories popular from the 1950s to 2011 incorrectly stated that inequality had a positive effect on economic development. Analyses based on comparing yearly equality figures to yearly growth rates were misleading because it takes several years for effects to manifest as changes to economic growth. IMF economists found a strong association between lower levels of inequality in developing countries and sustained periods of economic growth. Developing countries with high inequality have "succeeded in initiating growth at high rates for a few years" but "longer growth spells are robustly associated with more equality in the income distribution."

Problems that can be solved in theory (e.g., given large but finite time), but which in practice take too long for their solutions to be useful, are known as intractable problems. In complexity theory, problems that lack polynomial-time solutions are considered to be intractable for more than the smallest inputs. In fact, the Cobham–Edmonds thesis states that only those problems that can be solved in polynomial time can be feasibly computed on some computational device. Problems that are known to be intractable in this sense include those that are EXPTIME-hard. If NP is not the same as P, then the NP-complete problems are also intractable in this sense. To see why exponential-time algorithms might be unusable in practice, consider a program that makes 2n operations before halting. For small n, say 100, and assuming for the sake of example that the computer does 1012 operations each second, the program would run for about 4 × 1010 years, which is the same order of magnitude as the age of the universe. Even with a much faster computer, the program would only be useful for very small instances and in that sense the intractability of a problem is somewhat independent of technological progress. Nevertheless, a polynomial time algorithm is not always practical. If its running time is, say, n15, it is unreasonable to consider it efficient and it is still useless except on small instances.

There is also a growing number of new forms of procurement that involve relationship contracting where the emphasis is on a co-operative relationship between the principal and contractor and other stakeholders within a construction project. New forms include partnering such as Public-Private Partnering (PPPs) aka private finance initiatives (PFIs) and alliances such as "pure" or "project" alliances and "impure" or "strategic" alliances. The focus on co-operation is to ameliorate the many problems that arise from the often highly competitive and adversarial practices within the construction industry.

Ctenophora (/tᵻˈnɒfərə/; singular ctenophore, /ˈtɛnəfɔːr/ or /ˈtiːnəfɔːr/; from the Greek κτείς kteis 'comb' and φέρω pherō 'carry'; commonly known as comb jellies) is a phylum of animals that live in marine waters worldwide. Their most distinctive feature is the ‘combs’ – groups of cilia which they use for swimming – they are the largest animals that swim by means of cilia. Adults of various species range from a few millimeters to 1.5 m (4 ft 11 in) in size. Like cnidarians, their bodies consist of a mass of jelly, with one layer of cells on the outside and another lining the internal cavity. In ctenophores, these layers are two cells deep, while those in cnidarians are only one cell deep. Some authors combined ctenophores and cnidarians in one phylum, Coelenterata, as both groups rely on water flow through the body cavity for both digestion and respiration. Increasing awareness of the differences persuaded more recent authors to classify them as separate phyla.

On the other hand, higher economic inequality tends to increase entrepreneurship rates at the individual level (self-employment). However, most of it is often based on necessity rather than opportunity. Necessity-based entrepreneurship is motivated by survival needs such as income for food and shelter ("push" motivations), whereas opportunity-based entrepreneurship is driven by achievement-oriented motivations ("pull") such as vocation and more likely to involve the pursue of new products, services, or underserved market needs. The economic impact of the former type of entrepreneurialism tends to be redistributive while the latter is expected to foster technological progress and thus have a more positive impact on economic growth.

Lake Constance consists of three bodies of water: the Obersee ("upper lake"), the Untersee ("lower lake"), and a connecting stretch of the Rhine, called the Seerhein ("Lake Rhine"). The lake is situated in Germany, Switzerland and Austria near the Alps. Specifically, its shorelines lie in the German states of Bavaria and Baden-Württemberg, the Austrian state of Vorarlberg, and the Swiss cantons of Thurgau and St. Gallen. The Rhine flows into it from the south following the Swiss-Austrian border. It is located at approximately 47°39′N 9°19′E / 47.650°N 9.317°E / 47.650; 9.317.

Stage 1 is the first, or introductory stage of the bill, where the minister or member in charge of the bill will formally introduce it to Parliament together with its accompanying documents – Explanatory Notes, a Policy Memorandum setting out the policy underlying the bill, and a Financial Memorandum setting out the costs and savings associated with it. Statements from the Presiding Officer and the member in charge of the bill are also lodged indicating whether the bill is within the legislative competence of the Parliament. Stage 1 usually takes place, initially, in the relevant committee or committees and is then submitted to the whole Parliament for a full debate in the chamber on the general principles of the bill. If the whole Parliament agrees in a vote to the general principles of the bill, it then proceeds to Stage 2.

What do statements from the PO and member in charge of the bill also indicate?


A problem is regarded as inherently difficult if its solution requires significant resources, whatever the algorithm used. The theory formalizes this intuition, by introducing mathematical models of computation to study these problems and quantifying the amount of resources needed to solve them, such as time and storage. Other complexity measures are also used, such as the amount of communication (used in communication complexity), the number of gates in a circuit (used in circuit complexity) and the number of processors (used in parallel computing). One of the roles of computational complexity theory is to determine the practical limits on what computers can and cannot do.

The Rhine is the longest river in Germany. It is here that the Rhine encounters some more of its main tributaries, such as the Neckar, the Main and, later, the Moselle, which contributes an average discharge of more than 300 m3/s (11,000 cu ft/s). Northeastern France drains to the Rhine via the Moselle; smaller rivers drain the Vosges and Jura Mountains uplands. Most of Luxembourg and a very small part of Belgium also drain to the Rhine via the Moselle. As it approaches the Dutch border, the Rhine has an annual mean discharge of 2,290 m3/s (81,000 cu ft/s) and an average width of 400 m (1,300 ft).

Read this: While studying law and philosophy in England and Germany, Iqbal became a member of the London branch of the All India Muslim League. He came back to Lahore in 1908. While dividing his time between law practice and philosophical poetry, Iqbal had remained active in the Muslim League. He did not support Indian involvement in World War I and remained in close touch with Muslim political leaders such as Muhammad Ali Johar and Muhammad Ali Jinnah. He was a critic of the mainstream Indian nationalist and secularist Indian National Congress. Iqbal's seven English lectures were published by Oxford University press in 1934 in a book titled The Reconstruction of Religious Thought in Islam. These lectures dwell on the role of Islam as a religion as well as a political and legal philosophy in the modern age.

Before Rollo's arrival, its populations did not differ from Picardy or the Île-de-France, which were considered "Frankish". Earlier Viking settlers had begun arriving in the 880s, but were divided between colonies in the east (Roumois and Pays de Caux) around the low Seine valley and in the west in the Cotentin Peninsula, and were separated by traditional pagii, where the population remained about the same with almost no foreign settlers. Rollo's contingents who raided and ultimately settled Normandy and parts of the Atlantic coast included Danes, Norwegians, Norse–Gaels, Orkney Vikings, possibly Swedes, and Anglo-Danes from the English Danelaw under Norse control.

When did Rollo begin to arrive in Normandy?


The main use for steam turbines is in electricity generation (in the 1990s about 90% of the world's electric production was by use of steam turbines) however the recent widespread application of large gas turbine units and typical combined cycle power plants has resulted in reduction of this percentage to the 80% regime for steam turbines. In electricity production, the high speed of turbine rotation matches well with the speed of modern electric generators, which are typically direct connected to their driving turbines. In marine service, (pioneered on the Turbinia), steam turbines with reduction gearing (although the Turbinia has direct turbines to propellers with no reduction gearbox) dominated large ship propulsion throughout the late 20th century, being more efficient (and requiring far less maintenance) than reciprocating steam engines. In recent decades, reciprocating Diesel engines, and gas turbines, have almost entirely supplanted steam propulsion for marine applications.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What gearing was used on steam turbine marine engines in the 20th century?

For most of human history higher material living standards – full stomachs, access to clean water and warmth from fuel – led to better health and longer lives. This pattern of higher incomes-longer lives still holds among poorer countries, where life expectancy increases rapidly as per capita income increases, but in recent decades it has slowed down among middle income countries and plateaued among the richest thirty or so countries in the world. Americans live no longer on average (about 77 years in 2004) than Greeks (78 years) or New Zealanders (78), though the USA has a higher GDP per capita. Life expectancy in Sweden (80 years) and Japan (82) – where income was more equally distributed – was longer.

Where does the pattern of higher income-longer lives still hold true?

What we now call gravity was not identified as a universal force until the work of Isaac Newton. Before Newton, the tendency for objects to fall towards the Earth was not understood to be related to the motions of celestial objects. Galileo was instrumental in describing the characteristics of falling objects by determining that the acceleration of every object in free-fall was constant and independent of the mass of the object. Today, this acceleration due to gravity towards the surface of the Earth is usually designated as  and has a magnitude of about 9.81 meters per second squared (this measurement is taken from sea level and may vary depending on location), and points toward the center of the Earth. This observation means that the force of gravity on an object at the Earth's surface is directly proportional to the object's mass. Thus an object that has a mass of  will experience a force:

The war was fought primarily along the frontiers between New France and the British colonies, from Virginia in the South to Nova Scotia in the North. It began with a dispute over control of the confluence of the Allegheny and Monongahela rivers, called the Forks of the Ohio, and the site of the French Fort Duquesne and present-day Pittsburgh, Pennsylvania. The dispute erupted into violence in the Battle of Jumonville Glen in May 1754, during which Virginia militiamen under the command of 22-year-old George Washington ambushed a French patrol.

Scottish Parliament:

The outcome of most votes can be predicted beforehand since political parties normally instruct members which way to vote. Parties entrust some MSPs, known as whips, with the task of ensuring that party members vote according to the party line. MSPs do not tend to vote against such instructions, since those who do are unlikely to reach higher political ranks in their parties. Errant members can be deselected as official party candidates during future elections, and, in serious cases, may be expelled from their parties outright. Thus, as with many Parliaments, the independence of Members of the Scottish Parliament tends to be low, and backbench rebellions by members who are discontent with their party's policies are rare. In some circumstances, however, parties announce "free votes", which allows Members to vote as they please. This is typically done on moral issues.

In the United Kingdom and several other Commonwealth countries including Australia and Canada, the use of the term is generally restricted to primary and secondary educational levels; it is almost never used of universities and other tertiary institutions. Private education in North America covers the whole gamut of educational activity, ranging from pre-school to tertiary level institutions. Annual tuition fees at K-12 schools range from nothing at so called 'tuition-free' schools to more than $45,000 at several New England preparatory schools.

Their local rivals, Polonia Warsaw, have significantly fewer supporters, yet they managed to win Ekstraklasa Championship in 2000. They also won the country’s championship in 1946, and won the cup twice as well. Polonia's home venue is located at Konwiktorska Street, a ten-minute walk north from the Old Town. Polonia was relegated from the country's top flight in 2013 because of their disastrous financial situation. They are now playing in the 4th league (5th tier in Poland) -the bottom professional league in the National – Polish Football Association (PZPN) structure.

Why was Polonia relegated from the country's top flight in 2013?


Many questions regarding prime numbers remain open, such as Goldbach's conjecture (that every even integer greater than 2 can be expressed as the sum of two primes), and the twin prime conjecture (that there are infinitely many pairs of primes whose difference is 2). Such questions spurred the development of various branches of number theory, focusing on analytic or algebraic aspects of numbers. Primes are used in several routines in information technology, such as public-key cryptography, which makes use of properties such as the difficulty of factoring large numbers into their prime factors. Prime numbers give rise to various generalizations in other mathematical domains, mainly algebra, such as prime elements and prime ideals.

Answer this question, if possible (if impossible, reply "unanswerable"): Besides the analytic property of Goldbach's conjecture, what other property of Goldbach's conjecture does number theory focus on?


In 2007, BSkyB and Virgin Media became involved in a dispute over the carriage of Sky channels on cable TV. The failure to renew the existing carriage agreements negotiated with NTL and Telewest resulted in Virgin Media removing the basic channels from the network on 1 March 2007. Virgin Media claimed that BSkyB had substantially increased the asking price for the channels, a claim which BSkyB denied, on the basis that their new deal offered "substantially more value" by including HD channels and Video On Demand content which was not previously carried by cable.

Civil disobedience:

It has been argued that the term "civil disobedience" has always suffered from ambiguity and in modern times, become utterly debased. Marshall Cohen notes, "It has been used to describe everything from bringing a test-case in the federal courts to taking aim at a federal official. Indeed, for Vice President Agnew it has become a code-word describing the activities of muggers, arsonists, draft evaders, campaign hecklers, campus militants, anti-war demonstrators, juvenile delinquents and political assassins."

University of Chicago:

The University of Chicago was created and incorporated as a coeducational, secular institution in 1890 by the American Baptist Education Society and a donation from oil magnate and philanthropist John D. Rockefeller on land donated by Marshall Field. While the Rockefeller donation provided money for academic operations and long-term endowment, it was stipulated that such money could not be used for buildings. The original physical campus was financed by donations from wealthy Chicagoans like Silas B. Cobb who provided the funds for the campus' first building, Cobb Lecture Hall, and matched Marshall Field's pledge of $100,000. Other early benefactors included businessmen Charles L. Hutchinson (trustee, treasurer and donor of Hutchinson Commons), Martin A. Ryerson (president of the board of trustees and donor of the Ryerson Physical Laboratory) Adolphus Clay Bartlett and Leon Mandel, who funded the construction of the gymnasium and assembly hall, and George C. Walker of the Walker Museum, a relative of Cobb who encouraged his inaugural donation for facilities.

The French acquired a copy of the British war plans, including the activities of Shirley and Johnson. Shirley's efforts to fortify Oswego were bogged down in logistical difficulties, exacerbated by Shirley's inexperience in managing large expeditions. In conjunction, Shirley was made aware that the French were massing for an attack on Fort Oswego in his absence when he planned to attack Fort Niagara. As a response, Shirley left garrisons at Oswego, Fort Bull, and Fort Williams (the latter two located on the Oneida Carry between the Mohawk River and Wood Creek at present-day Rome, New York). Supplies for use in the projected attack on Niagara were cached at Fort Bull.

Read this: Ctenophora (/tᵻˈnɒfərə/; singular ctenophore, /ˈtɛnəfɔːr/ or /ˈtiːnəfɔːr/; from the Greek κτείς kteis 'comb' and φέρω pherō 'carry'; commonly known as comb jellies) is a phylum of animals that live in marine waters worldwide. Their most distinctive feature is the ‘combs’ – groups of cilia which they use for swimming – they are the largest animals that swim by means of cilia. Adults of various species range from a few millimeters to 1.5 m (4 ft 11 in) in size. Like cnidarians, their bodies consist of a mass of jelly, with one layer of cells on the outside and another lining the internal cavity. In ctenophores, these layers are two cells deep, while those in cnidarians are only one cell deep. Some authors combined ctenophores and cnidarians in one phylum, Coelenterata, as both groups rely on water flow through the body cavity for both digestion and respiration. Increasing awareness of the differences persuaded more recent authors to classify them as separate phyla.

In World War II, Charles de Gaulle and the Free French used the overseas colonies as bases from which they fought to liberate France. However after 1945 anti-colonial movements began to challenge the Empire. France fought and lost a bitter war in Vietnam in the 1950s. Whereas they won the war in Algeria, the French leader at the time, Charles de Gaulle, decided to grant Algeria independence anyway in 1962. Its settlers and many local supporters relocated to France. Nearly all of France's colonies gained independence by 1960, but France retained great financial and diplomatic influence. It has repeatedly sent troops to assist its former colonies in Africa in suppressing insurrections and coups d’état.

The tentacles of cydippid ctenophores are typically fringed with tentilla ("little tentacles"), although a few genera have simple tentacles without these sidebranches. The tentacles and tentilla are densely covered with microscopic colloblasts that capture prey by sticking to it. Colloblasts are specialized mushroom-shaped cells in the outer layer of the epidermis, and have three main components: a domed head with vesicles (chambers) that contain adhesive; a stalk that anchors the cell in the lower layer of the epidermis or in the mesoglea; and a spiral thread that coils round the stalk and is attached to the head and to the root of the stalk. The function of the spiral thread is uncertain, but it may absorb stress when prey tries to escape, and thus prevent the collobast from being torn apart. In addition to colloblasts, members of the genus Haeckelia, which feed mainly on jellyfish, incorporate their victims' stinging nematocytes into their own tentacles – some cnidaria-eating nudibranchs similarly incorporate nematocytes into their bodies for defense. The tentilla of Euplokamis differ significantly from those of other cydippids: they contain striated muscle, a cell type otherwise unknown in the phylum Ctenophora; and they are coiled when relaxed, while the tentilla of all other known ctenophores elongate when relaxed. Euplokamis' tentilla have three types of movement that are used in capturing prey: they may flick out very quickly (in 40 to 60 milliseconds); they can wriggle, which may lure prey by behaving like small planktonic worms; and they coil round prey. The unique flicking is an uncoiling movement powered by contraction of the striated muscle. The wriggling motion is produced by smooth muscles, but of a highly specialized type. Coiling around prey is accomplished largely by the return of the tentilla to their inactive state, but the coils may be tightened by smooth muscle.

After World War II, under a Communist regime set up by the conquering Soviets, the "Bricks for Warsaw" campaign was initiated, and large prefabricated housing projects were erected in Warsaw to address the housing shortage, along with other typical buildings of an Eastern Bloc city, such as the Palace of Culture and Science, a gift from the Soviet Union. The city resumed its role as the capital of Poland and the country's centre of political and economic life. Many of the historic streets, buildings, and churches were restored to their original form. In 1980, Warsaw's historic Old Town was inscribed onto UNESCO's World Heritage list.

Immune system:

Helper T cells express T cell receptors (TCR) that recognize antigen bound to Class II MHC molecules. The MHC:antigen complex is also recognized by the helper cell's CD4 co-receptor, which recruits molecules inside the T cell (e.g., Lck) that are responsible for the T cell's activation. Helper T cells have a weaker association with the MHC:antigen complex than observed for killer T cells, meaning many receptors (around 200–300) on the helper T cell must be bound by an MHC:antigen in order to activate the helper cell, while killer T cells can be activated by engagement of a single MHC:antigen molecule. Helper T cell activation also requires longer duration of engagement with an antigen-presenting cell. The activation of a resting helper T cell causes it to release cytokines that influence the activity of many cell types. Cytokine signals produced by helper T cells enhance the microbicidal function of macrophages and the activity of killer T cells. In addition, helper T cell activation causes an upregulation of molecules expressed on the T cell's surface, such as CD40 ligand (also called CD154), which provide extra stimulatory signals typically required to activate antibody-producing B cells.

The area of the modern city of Jacksonville has been inhabited for thousands of years. On Black Hammock Island in the national Timucuan Ecological and Historic Preserve, a University of North Florida team discovered some of the oldest remnants of pottery in the United States, dating to 2500 BC. In the 16th century, the beginning of the historical era, the region was inhabited by the Mocama, a coastal subgroup of the Timucua people. At the time of contact with Europeans, all Mocama villages in present-day Jacksonville were part of the powerful chiefdom known as the Saturiwa, centered around the mouth of the St. Johns River. One early map shows a village called Ossachite at the site of what is now downtown Jacksonville; this may be the earliest recorded name for that area.

The new British command was not in place until July. When he arrived in Albany, Abercrombie refused to take any significant actions until Loudoun approved them. Montcalm took bold action against his inertia. Building on Vaudreuil's work harassing the Oswego garrison, Montcalm executed a strategic feint by moving his headquarters to Ticonderoga, as if to presage another attack along Lake George. With Abercrombie pinned down at Albany, Montcalm slipped away and led the successful attack on Oswego in August. In the aftermath, Montcalm and the Indians under his command disagreed about the disposition of prisoners' personal effects. The Europeans did not consider them prizes and prevented the Indians from stripping the prisoners of their valuables, which angered the Indians.

Read this: Gamma delta T cells (γδ T cells) possess an alternative T cell receptor (TCR) as opposed to CD4+ and CD8+ (αβ) T cells and share the characteristics of helper T cells, cytotoxic T cells and NK cells. The conditions that produce responses from γδ T cells are not fully understood. Like other 'unconventional' T cell subsets bearing invariant TCRs, such as CD1d-restricted Natural Killer T cells, γδ T cells straddle the border between innate and adaptive immunity. On one hand, γδ T cells are a component of adaptive immunity as they rearrange TCR genes to produce receptor diversity and can also develop a memory phenotype. On the other hand, the various subsets are also part of the innate immune system, as restricted TCR or NK receptors may be used as pattern recognition receptors. For example, large numbers of human Vγ9/Vδ2 T cells respond within hours to common molecules produced by microbes, and highly restricted Vδ1+ T cells in epithelia respond to stressed epithelial cells.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): What type of T cells help with both innnate and adaptive immunity?

Commissioners have various privileges, such as being exempt from member state taxes (but not EU taxes), and having immunity from prosecution for doing official acts. Commissioners have sometimes been found to have abused their offices, particularly since the Santer Commission was censured by Parliament in 1999, and it eventually resigned due to corruption allegations. This resulted in one main case, Commission v Edith Cresson where the European Court of Justice held that a Commissioner giving her dentist a job, for which he was clearly unqualified, did in fact not break any law. By contrast to the ECJ's relaxed approach, a Committee of Independent Experts found that a culture had developed where few Commissioners had ‘even the slightest sense of responsibility’. This led to the creation of the European Anti-fraud Office. In 2012 it investigated the Maltese Commissioner for Health, John Dalli, who quickly resigned after allegations that he received a €60m bribe in connection with a Tobacco Products Directive. Beyond the Commission, the European Central Bank has relative executive autonomy in its conduct of monetary policy for the purpose of managing the euro. It has a six-person board appointed by the European Council, on the Council's recommendation. The President of the Council and a Commissioner can sit in on ECB meetings, but do not have voting rights.

Islamism:

Islamism, also known as Political Islam (Arabic: إسلام سياسي islām siyāsī), is an Islamic revival movement often characterized by moral conservatism, literalism, and the attempt "to implement Islamic values in all spheres of life." Islamism favors the reordering of government and society in accordance with the Shari'a. The different Islamist movements have been described as "oscillating between two poles": at one end is a strategy of Islamization of society through state power seized by revolution or invasion; at the other "reformist" pole Islamists work to Islamize society gradually "from the bottom up". The movements have "arguably altered the Middle East more than any trend since the modern states gained independence", redefining "politics and even borders" according to one journalist (Robin Wright).

Read this: Since ~3000 yr BP (= years Before Present), human impact is seen in the delta. As a result of increasing land clearance (Bronze Age agriculture), in the upland areas (central Germany), the sediment load of the Rhine has strongly increased and delta growth has sped up. This caused increased flooding and sedimentation, ending peat formation in the delta. The shifting of river channels to new locations, on the floodplain (termed avulsion), was the main process distributing sediment across the subrecent delta. Over the past 6000 years, approximately 80 avulsions have occurred. Direct human impact in the delta started with peat mining, for salt and fuel, from Roman times onward. This was followed by embankment, of the major distributaries and damming of minor distributaries, which took place in the 11–13th century AD. Thereafter, canals were dug, bends were short cut and groynes were built, to prevent the river's channels from migrating or silting up.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): How long did peat mining from the Roman times last for?

Neutrophils and macrophages are phagocytes that travel throughout the body in pursuit of invading pathogens. Neutrophils are normally found in the bloodstream and are the most abundant type of phagocyte, normally representing 50% to 60% of the total circulating leukocytes. During the acute phase of inflammation, particularly as a result of bacterial infection, neutrophils migrate toward the site of inflammation in a process called chemotaxis, and are usually the first cells to arrive at the scene of infection. Macrophages are versatile cells that reside within tissues and produce a wide array of chemicals including enzymes, complement proteins, and regulatory factors such as interleukin 1. Macrophages also act as scavengers, ridding the body of worn-out cells and other debris, and as antigen-presenting cells that activate the adaptive immune system.

Warsaw is located on two main geomorphologic formations: the plain moraine plateau and the Vistula Valley with its asymmetrical pattern of different terraces. The Vistula River is the specific axis of Warsaw, which divides the city into two parts, left and right. The left one is situated both on the moraine plateau (10 to 25 m (32.8 to 82.0 ft) above Vistula level) and on the Vistula terraces (max. 6.5 m (21.3 ft) above Vistula level). The significant element of the relief, in this part of Warsaw, is the edge of moraine plateau called Warsaw Escarpment. It is 20 to 25 m (65.6 to 82.0 ft) high in the Old Town and Central district and about 10 m (32.8 ft) in the north and south of Warsaw. It goes through the city and plays an important role as a landmark.

The Treaties contain formal and substantive provisions, which frame policies of the European Union institutions and determine the division of competences between the European Union and its member states. The TEU establishes that European Union law applies to the metropolitan territories of the member states, as well as certain islands and overseas territories, including Madeira, the Canary Islands and the French overseas departments. European Union law also applies in territories where a member state is responsible for external relations, for example Gibraltar and the Åland islands. The TEU allows the European Council to make specific provisions for regions, as for example done for customs matters in Gibraltar and Saint-Pierre-et-Miquelon. The TEU specifically excludes certain regions, for example the Faroe Islands, from the jurisdiction of European Union law. Treaties apply as soon as they enter into force, unless stated otherwise, and are generally concluded for an unlimited period. The TEU provides that commitments entered into by the member states between themselves before the treaty was signed no longer apply.[vague] All EU member states are regarded as subject to the general obligation of the principle of cooperation, as stated in the TEU, whereby member states are obliged not to take measure which could jeopardise the attainment of the TEU objectives. The Court of Justice of the European Union can interpret the Treaties, but it cannot rule on their validity, which is subject to international law. Individuals may rely on primary law in the Court of Justice of the European Union if the Treaty provisions have a direct effect and they are sufficiently clear, precise and unconditional.

Disorders of the immune system can result in autoimmune diseases, inflammatory diseases and cancer. Immunodeficiency occurs when the immune system is less active than normal, resulting in recurring and life-threatening infections. In humans, immunodeficiency can either be the result of a genetic disease such as severe combined immunodeficiency, acquired conditions such as HIV/AIDS, or the use of immunosuppressive medication. In contrast, autoimmunity results from a hyperactive immune system attacking normal tissues as if they were foreign organisms. Common autoimmune diseases include Hashimoto's thyroiditis, rheumatoid arthritis, diabetes mellitus type 1, and systemic lupus erythematosus. Immunology covers the study of all aspects of the immune system.

What is not caused by disorders of the immune system?


At the same time the Mongols imported Central Asian Muslims to serve as administrators in China, the Mongols also sent Han Chinese and Khitans from China to serve as administrators over the Muslim population in Bukhara in Central Asia, using foreigners to curtail the power of the local peoples of both lands. Han Chinese were moved to Central Asian areas like Besh Baliq, Almaliq, and Samarqand by the Mongols where they worked as artisans and farmers. Alans were recruited into the Mongol forces with one unit called "Right Alan Guard" which was combined with "recently surrendered" soldiers, Mongols, and Chinese soldiers stationed in the area of the former Kingdom of Qocho and in Besh Balikh the Mongols established a Chinese military colony led by Chinese general Qi Kongzhi (Ch'i Kung-chih). After the Mongol conquest of Central Asia by Genghis Khan, foreigners were chosen as administrators and co-management with Chinese and Qara-Khitays (Khitans) of gardens and fields in Samarqand was put upon the Muslims as a requirement since Muslims were not allowed to manage without them. The Mongol appointed Governor of Samarqand was a Qara-Khitay (Khitan), held the title Taishi, familiar with Chinese culture his name was Ahai

Read this: Since the IPCC does not carry out its own research, it operates on the basis of scientific papers and independently documented results from other scientific bodies, and its schedule for producing reports requires a deadline for submissions prior to the report's final release. In principle, this means that any significant new evidence or events that change our understanding of climate science between this deadline and publication of an IPCC report cannot be included. In an area of science where our scientific understanding is rapidly changing, this has been raised as a serious shortcoming in a body which is widely regarded as the ultimate authority on the science. However, there has generally been a steady evolution of key findings and levels of scientific confidence from one assessment report to the next.[citation needed]
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): What organization is responsible for their own research?


Amazon rainforest:

The first European to travel the length of the Amazon River was Francisco de Orellana in 1542. The BBC's Unnatural Histories presents evidence that Orellana, rather than exaggerating his claims as previously thought, was correct in his observations that a complex civilization was flourishing along the Amazon in the 1540s. It is believed that the civilization was later devastated by the spread of diseases from Europe, such as smallpox. Since the 1970s, numerous geoglyphs have been discovered on deforested land dating between AD 0–1250, furthering claims about Pre-Columbian civilizations. Ondemar Dias is accredited with first discovering the geoglyphs in 1977 and Alceu Ranzi with furthering their discovery after flying over Acre. The BBC's Unnatural Histories presented evidence that the Amazon rainforest, rather than being a pristine wilderness, has been shaped by man for at least 11,000 years through practices such as forest gardening and terra preta.

Please answer a question about this article. If the question is unanswerable, say "unanswerable". Who was the first European to travel the entire length of the Amazon River?


Harvard is a large, highly residential research university. The nominal cost of attendance is high, but the University's large endowment allows it to offer generous financial aid packages. It operates several arts, cultural, and scientific museums, alongside the Harvard Library, which is the world's largest academic and private library system, comprising 79 individual libraries with over 18 million volumes. Harvard's alumni include eight U.S. presidents, several foreign heads of state, 62 living billionaires, 335 Rhodes Scholars, and 242 Marshall Scholars. To date, some 150 Nobel laureates, 18 Fields Medalists and 13 Turing Award winners have been affiliated as students, faculty, or staff.

Trioxygen (O
3) is usually known as ozone and is a very reactive allotrope of oxygen that is damaging to lung tissue. Ozone is produced in the upper atmosphere when O
2 combines with atomic oxygen made by the splitting of O
2 by ultraviolet (UV) radiation. Since ozone absorbs strongly in the UV region of the spectrum, the ozone layer of the upper atmosphere functions as a protective radiation shield for the planet. Near the Earth's surface, it is a pollutant formed as a by-product of automobile exhaust. The metastable molecule tetraoxygen (O
4) was discovered in 2001, and was assumed to exist in one of the six phases of solid oxygen. It was proven in 2006 that this phase, created by pressurizing O
2 to 20 GPa, is in fact a rhombohedral O
8 cluster. This cluster has the potential to be a much more powerful oxidizer than either O
2 or O
3 and may therefore be used in rocket fuel. A metallic phase was discovered in 1990 when solid oxygen is subjected to a pressure of above 96 GPa and it was shown in 1998 that at very low temperatures, this phase becomes superconducting.
Try to answer this question if possible (otherwise reply "unanswerable"): What was discovered in 2006 in regard to O4?

Due to the fact that the bureaucracy was dominated by El Temür, Tugh Temür is known for his cultural contribution instead. He adopted many measures honoring Confucianism and promoting Chinese cultural values. His most concrete effort to patronize Chinese learning was founding the Academy of the Pavilion of the Star of Literature (Chinese: 奎章閣學士院), first established in the spring of 1329 and designed to undertake "a number of tasks relating to the transmission of Confucian high culture to the Mongolian imperial establishment". The academy was responsible for compiling and publishing a number of books, but its most important achievement was its compilation of a vast institutional compendium named Jingshi Dadian (Chinese: 經世大典). Tugh Temür supported Zhu Xi's Neo-Confucianism and also devoted himself in Buddhism.

Since forces are perceived as pushes or pulls, this can provide an intuitive understanding for describing forces. As with other physical concepts (e.g. temperature), the intuitive understanding of forces is quantified using precise operational definitions that are consistent with direct observations and compared to a standard measurement scale. Through experimentation, it is determined that laboratory measurements of forces are fully consistent with the conceptual definition of force offered by Newtonian mechanics.

How are laboratory measurements of forces determined?


Amazon rainforest:

As indigenous territories continue to be destroyed by deforestation and ecocide, such as in the Peruvian Amazon indigenous peoples' rainforest communities continue to disappear, while others, like the Urarina continue to struggle to fight for their cultural survival and the fate of their forested territories. Meanwhile, the relationship between non-human primates in the subsistence and symbolism of indigenous lowland South American peoples has gained increased attention, as have ethno-biology and community-based conservation efforts.

Please answer a question about this article. If the question is unanswerable, say "unanswerable". Indigenous territories are being preserved through what type of conservation efforts?


The Rhine is the longest river in Germany. It is here that the Rhine encounters some more of its main tributaries, such as the Neckar, the Main and, later, the Moselle, which contributes an average discharge of more than 300 m3/s (11,000 cu ft/s). Northeastern France drains to the Rhine via the Moselle; smaller rivers drain the Vosges and Jura Mountains uplands. Most of Luxembourg and a very small part of Belgium also drain to the Rhine via the Moselle. As it approaches the Dutch border, the Rhine has an annual mean discharge of 2,290 m3/s (81,000 cu ft/s) and an average width of 400 m (1,300 ft).
Try to answer this question if possible (otherwise reply "unanswerable"): Which country does the Rhine encounter it's main tributaries?


The Harvard Crimson competes in 42 intercollegiate sports in the NCAA Division I Ivy League. Harvard has an intense athletic rivalry with Yale University culminating in The Game, although the Harvard–Yale Regatta predates the football game. This rivalry, though, is put aside every two years when the Harvard and Yale Track and Field teams come together to compete against a combined Oxford University and Cambridge University team, a competition that is the oldest continuous international amateur competition in the world.

Compact trucks were introduced, such as the Toyota Hilux and the Datsun Truck, followed by the Mazda Truck (sold as the Ford Courier), and the Isuzu-built Chevrolet LUV. Mitsubishi rebranded its Forte as the Dodge D-50 a few years after the oil crisis. Mazda, Mitsubishi and Isuzu had joint partnerships with Ford, Chrysler, and GM, respectively. Later the American makers introduced their domestic replacements (Ford Ranger, Dodge Dakota and the Chevrolet S10/GMC S-15), ending their captive import policy.

Answer this question, if possible (if impossible, reply "unanswerable"): Mazda, Mitsubishi and Isuzu joined partnership with which American car company?


Prime ideals are the points of algebro-geometric objects, via the notion of the spectrum of a ring. Arithmetic geometry also benefits from this notion, and many concepts exist in both geometry and number theory. For example, factorization or ramification of prime ideals when lifted to an extension field, a basic problem of algebraic number theory, bears some resemblance with ramification in geometry. Such ramification questions occur even in number-theoretic questions solely concerned with integers. For example, prime ideals in the ring of integers of quadratic number fields can be used in proving quadratic reciprocity, a statement that concerns the solvability of quadratic equations
Is there an answer to this question (If it cannot be answered, say "unanswerable"): What does factorization of prime ideals approximate?

Each chapter has a number of authors who are responsible for writing and editing the material. A chapter typically has two "coordinating lead authors", ten to fifteen "lead authors", and a somewhat larger number of "contributing authors". The coordinating lead authors are responsible for assembling the contributions of the other authors, ensuring that they meet stylistic and formatting requirements, and reporting to the Working Group chairs. Lead authors are responsible for writing sections of chapters. Contributing authors prepare text, graphs or data for inclusion by the lead authors.

How many lead authors does an IPCC report chapter have?

One of its earliest massive implementations was brought about by Egyptians against the British occupation in the 1919 Revolution. Civil disobedience is one of the many ways people have rebelled against what they deem to be unfair laws. It has been used in many nonviolent resistance movements in India (Gandhi's campaigns for independence from the British Empire), in Czechoslovakia's Velvet Revolution and in East Germany to oust their communist governments, In South Africa in the fight against apartheid, in the American Civil Rights Movement, in the Singing Revolution to bring independence to the Baltic countries from the Soviet Union, recently with the 2003 Rose Revolution in Georgia and the 2004 Orange Revolution in Ukraine, among other various movements worldwide.

Which people brought forward one of the earliest examples of Civil Disobedience?


Read this: Oxygen is a chemical element with symbol O and atomic number 8. It is a member of the chalcogen group on the periodic table and is a highly reactive nonmetal and oxidizing agent that readily forms compounds (notably oxides) with most elements. By mass, oxygen is the third-most abundant element in the universe, after hydrogen and helium. At standard temperature and pressure, two atoms of the element bind to form dioxygen, a colorless and odorless diatomic gas with the formula O
2. Diatomic oxygen gas constitutes 20.8% of the Earth's atmosphere. However, monitoring of atmospheric oxygen levels show a global downward trend, because of fossil-fuel burning. Oxygen is the most abundant element by mass in the Earth's crust as part of oxide compounds such as silicon dioxide, making up almost half of the crust's mass.

Which gas makes up 20.8% of the Earth's atmosphere?

Yuan dynasty:

The final years of the Yuan dynasty were marked by struggle, famine, and bitterness among the populace. In time, Kublai Khan's successors lost all influence on other Mongol lands across Asia, while the Mongols beyond the Middle Kingdom saw them as too Chinese. Gradually, they lost influence in China as well. The reigns of the later Yuan emperors were short and marked by intrigues and rivalries. Uninterested in administration, they were separated from both the army and the populace, and China was torn by dissension and unrest. Outlaws ravaged the country without interference from the weakening Yuan armies.

Please answer a question about this article. If the question is unanswerable, say "unanswerable". What problems did the Yuan dynasty have near its beginning?


Upper and lower bounds are usually stated using the big O notation, which hides constant factors and smaller terms. This makes the bounds independent of the specific details of the computational model used. For instance, if T(n) = 7n2 + 15n + 40, in big O notation one would write T(n) = O(n2).
Is there an answer to this question (If it cannot be answered, say "unanswerable"): What is usually not stated using the big O notation?


When some species, including Bathyctena chuni, Euplokamis stationis and Eurhamphaea vexilligera, are disturbed, they produce secretions (ink) that luminesce at much the same wavelengths as their bodies. Juveniles will luminesce more brightly in relation to their body size than adults, whose luminescence is diffused over their bodies. Detailed statistical investigation has not suggested the function of ctenophores' bioluminescence nor produced any correlation between its exact color and any aspect of the animals' environments, such as depth or whether they live in coastal or mid-ocean waters.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When do bathyctena chuni, euplokamis stationis and eurhamphaea vexilligera  excrete secretions?


Read this: Other evidence of the Walloons and Huguenots in Canterbury includes a block of houses in Turnagain Lane, where weavers' windows survive on the top floor, as many Huguenots worked as weavers. The Weavers, a half-timbered house by the river, was the site of a weaving school from the late 16th century to about 1830. (It has been adapted as a restaurant—see illustration above. The house derives its name from a weaving school which was moved there in the last years of the 19th century, reviving an earlier use.) Others refugees practised the variety of occupations necessary to sustain the community as distinct from the indigenous population. Such economic separation was the condition of the refugees' initial acceptance in the City. They also settled elsewhere in Kent, particularly Sandwich, Faversham and Maidstone—towns in which there used to be refugee churches.

During 2003–04, the gross value of Victorian agricultural production increased by 17% to $8.7 billion. This represented 24% of national agricultural production total gross value. As of 2004, an estimated 32,463 farms occupied around 136,000 square kilometres (52,500 sq mi) of Victorian land. This comprises more than 60% of the state's total land surface. Victorian farms range from small horticultural outfits to large-scale livestock and grain productions. A quarter of farmland is used to grow consumable crops.

How much did the gross agricultural product increase from 2003-04?


The connection between macroscopic nonconservative forces and microscopic conservative forces is described by detailed treatment with statistical mechanics. In macroscopic closed systems, nonconservative forces act to change the internal energies of the system, and are often associated with the transfer of heat. According to the Second law of thermodynamics, nonconservative forces necessarily result in energy transformations within closed systems from ordered to more random conditions as entropy increases.
Is there an answer to this question (If it cannot be answered, say "unanswerable"): What makes energy changes in a closed system?


Throughout the 1980s and 1990s, demand for a Scottish Parliament grew, in part because the government of the United Kingdom was controlled by the Conservative Party, while Scotland itself elected relatively few Conservative MPs. In the aftermath of the 1979 referendum defeat, the Campaign for a Scottish Assembly was initiated as a pressure group, leading to the 1989 Scottish Constitutional Convention with various organisations such as Scottish churches, political parties and representatives of industry taking part. Publishing its blueprint for devolution in 1995, the Convention provided much of the basis for the structure of the Parliament.
Demand for a Scottish Parliament declined in what year? (If the question is unanswerable, say "unanswerable")


Read this: The principle of cross-cutting relationships pertains to the formation of faults and the age of the sequences through which they cut. Faults are younger than the rocks they cut; accordingly, if a fault is found that penetrates some formations but not those on top of it, then the formations that were cut are older than the fault, and the ones that are not cut must be younger than the fault. Finding the key bed in these situations may help determine whether the fault is a normal fault or a thrust fault.

The system of bureaucracy created by Kublai Khan reflected various cultures in the empire, including that of the Han Chinese, Khitans, Jurchens, Mongols, and Tibetan Buddhists. While the official terminology of the institutions may indicate the government structure was almost purely that of native Chinese dynasties, the Yuan bureaucracy actually consisted of a mix of elements from different cultures. The Chinese-style elements of the bureaucracy mainly came from the native Tang, Song, as well as Khitan Liao and Jurchen Jin dynasties. Chinese advisers such as Liu Bingzhong and Yao Shu gave strong influence to Kublai's early court, and the central government administration was established within the first decade of Kublai's reign. This government adopted the traditional Chinese tripartite division of authority among civil, military, and censorial offices, including the Central Secretariat (Zhongshu Sheng) to manage civil affairs, the Privy Council (Chinese: 樞密院) to manage military affairs, and the Censorate to conduct internal surveillance and inspection. The actual functions of both central and local government institutions, however, showed a major overlap between the civil and military jurisdictions, due to the Mongol traditional reliance on military institutions and offices as the core of governance. Nevertheless, such a civilian bureaucracy, with the Central Secretariat as the top institution that was (directly or indirectly) responsible for most other governmental agencies (such as the traditional Chinese-style Six Ministries), was created in China. At various times another central government institution called the Department of State Affairs (Shangshu Sheng) that mainly dealt with finance was established (such as during the reign of Külüg Khan or Emperor Wuzong), but was usually abandoned shortly afterwards.
Try to answer this question if possible (otherwise reply "unanswerable"):  Who was the third of Kublai's Chinese advisers?


Though there is no official definition for the northern boundary of southern California, such a division has existed from the time when Mexico ruled California, and political disputes raged between the Californios of Monterey in the upper part and Los Angeles in the lower part of Alta California. Following the acquisition of California by the United States, the division continued as part of the attempt by several pro-slavery politicians to arrange the division of Alta California at 36 degrees, 30 minutes, the line of the Missouri Compromise. Instead, the passing of the Compromise of 1850 enabled California to be admitted to the Union as a free state, preventing southern California from becoming its own separate slave state.

For a precise definition of what it means to solve a problem using a given amount of time and space, a computational model such as the deterministic Turing machine is used. The time required by a deterministic Turing machine M on input x is the total number of state transitions, or steps, the machine makes before it halts and outputs the answer ("yes" or "no"). A Turing machine M is said to operate within time f(n), if the time required by M on each input of length n is at most f(n). A decision problem A can be solved in time f(n) if there exists a Turing machine operating in time f(n) that solves the problem. Since complexity theory is interested in classifying problems based on their difficulty, one defines sets of problems based on some criteria. For instance, the set of problems solvable within time f(n) on a deterministic Turing machine is then denoted by DTIME(f(n)).
