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>
seriously by scholars, they are good starting points for approaching the enormous complexity of the history of Europe's intellectual heritage. It is hoped that interested readers will pursue the listed topics in greater depth by consulting the respective articles and the suggestions for further reading. The intellectual history of western Europe and the Americas includes: Scholasticism: Associated especially with Aquinas and the recovery of Aristotle, a movement that was popular in universities and provided a new way of reasoning especially in law, philosophy, theology. Humanism: Humanists were associated with the discipline of rhetoric but they were not just orators, they also learned ancient languages, especially classical Greek and created new knowledge about the secular past. The revival of ancient literature and philosophy was of immense importance for the further development of European thought. The first humanist is considered to be Petrarch. Later exponents of note were Leonardo Bruni, Lorenzo Valla, and Erasmus of Rotterdam. The Renaissance: A movement in the arts and letters, it is associated particularly with humanism, but also with new trends in painting and with the efflorescence of a new courtly culture that from Italy (c.1350) spread across Europe in the 15th and 16th centuries. The New Philosophy: The 20th century dubbed this the Scientific Revolution, but in the 17th century, the new science was more often considered to be a new way of doing philosophy. It is associated mainly with the thought of Francis Bacon and Descartes. Other important philosophers were: Hobbes, Gassendi, Malebranche, Spinoza, Leibniz. Advances in astronomy were made by Copernicus, Brahe, Kepler and Galileo. The Royal Society: A secular creation of an intellectual world led by figures such as Isaac Newton, Robert Hooke, Christopher Wren, Joseph Addison, and Bishop Sprat. The Enlightenment: Key developments in thought included The rights of man, political representation, political economy, deism. Notable participants counted Bayle, Hume, Adam Smith, Adam Ferguson, Fontenelle, the Comte de Buffon, Kant, Voltaire, Rousseau, Diderot, Moses Mendelssohn, Vico. The Encyclopaedists: The creation of central repositories of knowledge available to all outside of academies, including mass-market encyclopaedias and dictionaries: Diderot, Samuel Johnson, Voltaire, and Ephraim Chambers. Romanticism : Individual, subjective, imaginative, personal, visionary (scholarly sources Carlyle, Rousseau, Hook, and Herder). Post-romanticism: Reaction to naturalism, opposes external-only observations by adding internal observations (scholarly sources Comte, von Ranke). Modernism : Rejects Christian academic scholarly tradition (scholarly sources Søren Kierkegaard, Friedrich Nietzsche, Jacob Burckhardt, Charles Beard, Ferdinand de Saussure, Sigmund Freud, Carl Jung). Pragmatism : Links the meaning of beliefs to the actions of a believer, and the truth of beliefs to success of those actions in securing a believer's goals. Charles Sanders Peirce, William James, John Dewey, F.C.S. Schiller, Richard Rorty. Originated in late nineteenth century America. Existentialism: Pre- and post-WW2 rejection of Western norms and cultural values. Søren Kierkegaard, Martin Heidegger, Jean-Paul Sartre, Simone de Beauvoir, Albert Camus, Hannah Arendt, Hans Jonas, Karl Löwith, Herbert Marcuse, Claude Lévi-Strauss, Martin Buber, Edmund Husserl. Engaged with the intellectual prominence of fascism and socialism in Europe in the 1930s and 1940s, which they saw needed both repudiation and study, as a way to re-establish the individual against the values of a hostile and destructive series of communities creating alienation, isolation, and individual meaninglessness. Postmodernism : Rejects Modernism, meta-narrative - multiple perspective, role of individual (scholarly sources Lyotard, Foucault, Barthes, Geertz). Structuralism : Many phenomena do not occur in isolation but in relation to each other (scholarly sources Geertz, Lévi-Strauss). Poststructuralism :Deconstruction, destabilizes the relationship between language and objects the language refers to (scholarly sources Lyotard, Derrida, Foucault).

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.
