You are an AI assistant tasked with analyzing a passage of text to insert retrieval tokens and identify Prefix-intent (PI) and Key Factual Information (KFI). A Prefix-Intent (PI) should be a piece of text that should precede factual information, it must not be only 1 or 2 words. Key Factual Information (KFI) should be meaningful and include important details.

Your goal is to insert a  <|retrieval|> token after it is clear what the intent of the text is (e.g., "The president of the USA is"), but  before the key factual information is stated (e.g., "Joe Biden"). Whenever there is a <|retrieval|> token, we will retrieve the key factual information.

Here is the passage you will be working with:

<passage>
States of the German Confederation The states of the German Confederation were those member states that from 20 June 1815 were part of the German Confederation, which lasted, with some changes in the member states, until 24 August 1866, under the presidency of the Austrian imperial House of Habsburg, which was represented by an Austrian presidential envoy to the Federal diet in Frankfurt. Explanation On the whole, its territory nearly coincided with that remaining in the Holy Roman Empire at the outbreak of the French Revolution, with the notable exception of Belgium. Except for the two rival major powers, Austria and Prussia, and the western left bank of the Rhine (which France had annexed, with tiny Katzenelnbogen), the other member states or their precursors, making up most of present Germany, had been within Napoleon's Confederation of the Rhine. The Austrian Empire, excluding the Kingdom of Hungary, the Principality of Transylvania, and the Kingdom of Croatia (all of which became parts of the apostolic kingdom of Hungary within the Danubian Dual Monarchy), the Kingdom of Lombardy–Venetia (constituting parts lost to Italy in 1859- viz. 1866), the Duchy of Bukovina, and the kingdoms of Dalmatia and Galicia Archduchy of Austria (split into Upper Austria and Lower Austria in 1849) Kingdom of Bohemia Margraviate of Moravia Grand Duchy of Salzburg Duchy of Carinthia Duchy of Carniola Duchy of Upper and Lower Silesia Duchy of Styria Littoral (consisting of Gorizia and Gradisca, Istria and Trieste) County of Tyrol Vorarlberg The Kingdom of Prussia (excluding Posen, East Prussia and West Prussia) Brandenburg Pomerania Rhine Province (until 1822 the Grand Duchy of the Lower Rhine and the Province of Jülich-Cleves-Berg) Saxony Silesia Westphalia The Kingdom of Bavaria (the third largest member) Upper Bavaria Upper Franconia Swabia Upper Palatinate Middle Franconia Lower Bavaria Lower Franconia Palatinate The Kingdom of Saxony The Kingdom of Hanover The Kingdom of Württemberg The Electorate of Hesse The Grand Duchy of Baden The Grand Duchy of Hesse The Duchy of Holstein (in personal union with the Kingdom of Denmark, was not a former member of the Confederation of the Rhine) The Duchy of Schleswig (a fief of Denmark and together with the Duchy of Holstein in personal union with the Kingdom of Denmark, was not a former member of either the Holy Roman Empire or the Confederation of the Rhine. The secessionist (pro-German) government of Schleswig-Holstein (1848–51) joined Schleswig to the Confederation. This was not recognized by the Confederation and the Danish government, and the peace settlement in 1851 specified that Schleswig was not a member. The Grand Duchy of Luxembourg (lost over half of its territory in the west to Belgium in the breakup of the United Kingdom of the Netherlands in 1839, and thereby causing Duchy of Limburg to become a member.) The Duchy of Limburg (became a member in 1839 as a compensation for territorial losses in the Grand Duchy of Luxembourg that were caused by the breakup of the United Kingdom of the Netherlands.) The Duchy of Brunswick (prior Brunswick-Lunenburgian Principality of Wolfenbüttel) The Grand Duchy of Mecklenburg-Schwerin The Duchy of Nassau The Grand Duchy of Saxe-Weimar-Eisenach The Duchy of Saxe-Gotha-Altenburg (to 1825) The Duchy of Saxe-Coburg-Saalfeld (to 1826) The Duchy of Saxe-Coburg and Gotha (from 1826) The Duchy of Saxe-Meiningen The Duchy of Saxe-Hildburghausen (Saxe-Altenburg from 1826) The Grand Duchy of Mecklenburg-Strelitz The Duchy of Oldenburg (Grand Duchy from 1829) The Duchy of Anhalt-Dessau (Duchy of Anhalt from 1863) The Duchy of Anhalt-Bernburg (to 1863) The Duchy of Anhalt-Köthen (to 1847) The Principality of Schwarzburg-Sondershausen The Principality of Schwarzburg-Rudolstadt The Principality of Hohenzollern-Hechingen (merged in Prussia in

Follow these steps to complete the task:

1. Inserting retrieval tokens:
   a. Read through the text carefully.
   b. Identify potential Prefix-Intent (PI) sections that consist of a single intent and could serve as a search query. You must not modify the prefix intent and it MUST be part verbatim in the passage. It cannot be single or only a few words.
   c. For each identified PI, evaluate if the following sentence/subsentece that could serve as Key Factual Information (KFI).
   d. Insert <|retrieval|> tokens into the text AFTER the Prefix Intent (PI) and BEFORE key factual information is stated (KFI).
   e. Key Factual information should not intersect with Prefix Intent.

2. Identifying Prefix-Intent (PI) and Key Factual Information (KFI):
   a. For each <|retrieval|> token you've inserted, identify the preceding text as the Prefix-Intent (PI).
   b. Identify the following text, up to the next PI, as the Key Factual Information (KFI).
   c. Ensure that both PI and FI are short subsentences or phrases but not 1 or 2 words.

3. Insert <|start-PI|>,<|end-PI|>, <|start-KFI|>, <|end-KFI|>.
   a. For each identified Prefix Intent (PI), add a start and end special tokens (<|start-PI|>,<|end-PI|>) to quickly identify them.
   b. Do the same for the Key Factual Information (KFI) (<|start-KFI|>, <|end-KFI|>)
   c. Ensure that the very first PI in the passage is preceded by <|start-PI|>.
   d. Double-check that every PI and KFI is properly enclosed in these tags.

4. Describing ideal retrieved information:
   a. Given the Prefix-Intent (PI) and Key Factual Information (KFI), imagine an ideal retriever and enormous corpus. 
   b. Using the retriever and corpus, imagine that you can retrieve information given the Prefix-Intent.  
   c. Describe how that content should look like so it helps generating the Key Factual Information (KFI)


5. Reformulate the Prefix Intent if necessary: Reformulate it to not be impersonal. This means that if the subject it is not identified (e.g. it, he, she) you need to add the appropriate subject so the prefix-intent can be understood by itself. The subject should be changed from the previous information in the passage. Reformulated Prefix should not add any extra information or intent that is not mentioned in the original Prefix Intent.


6. Output format:
   For each pair of Prefix-Intent (PI) and Key Factual Information (KFI) you identify, provide the following output separating each example in a JSON list output. Ensure that it is actually a JSON.

   - Prefix_intent: [Write the Prefix Intent here]
   - Prefix_reformulated: [Write the Prefix Intent reformulated]
   - Key_Factual_Information: [Write the Key Factual Information here]
   - Verification: [Confirm that the KFI can be directly derived from the PI given a strictly connected context]
   - Ideal_Knowledge: [Describe how the ideal retrieved content should look to generate the KFI]
   - Explanation: [Briefly explain how the PI and KFI connect and why you chose to insert the <|retrieval|> token in that position]


7. Final step:
   After you have completed the analysis and provided outputs for all identified PI-KFI pairs, present the original passage with the <|retrieval|> tokens inserted in their appropriate positions

Here's an example of the expected output format:

Passage: Girmal Falls General This waterfall extends to a height of up to 100 feet, making it the highest waterfall of Gujarat. The picturesque beauty of this site makes it popular among visitors and people of the region alike. The water swiftly falls from a great height, creating a fog like condition that’s eye catching. The government of this state is working on many projects to make this place an ideal picnic spot and a tourist attraction. The fall comes to its best form at the time of monsoon and provides an immensely striking appearance. Some of the best natural features of Gujarat can be explored in this place. This place is a nice and refreshing retreat for any traveler.
