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>
of the university's strongest specialties, owing to Iceland's unique literary heritage and nature. A growing number of English-taught programmes are offered in these fields and others, attracting a large number of foreign students. Rankings In 2011, Times Higher Education included the University of Iceland for the first time, placing it in the 276-300 band globally. The following year it had risen to the 251-275 band on the same list. Currently, Times ranks the university among the 201-250 best in the world. The 2017 edition of Academic Ranking of World Universities (ARWU) placed it in the 401-500 band globally. Student life Student funding The University of Iceland is a public, government-funded university and as such it does not charge tuition (although an enrollment fee must be paid). In terms of living expenses, most students at the University of Iceland either work part-time to finance their studies or receive student loans at favourable interest rates from the Icelandic Student Loan Fund. The Icelandic Ministry of Education, Science and Culture annually offers awards to foreign students for the study of Icelandic language, history and literature at the University of Iceland. Scholarships are usually restricted to students from selected countries each year. Awards are tenable for one academic year and aim to cover board and lodging. The major source of funding available to foreign graduate students is the Eimskipafélag Íslands University Fund, which is open to both scholars and current or prospective PhD students. Each grant from the fund is approximately 2.5 million ISK per year, for a period of up to three years and is intended to cover living expenses. Student politics, unions and services The Students' Council is the official representative of those studying at the university. It handles all kinds of rights issues and relations with internal and external authorities. Elections for the council take place every year. There are three major parties that participate in the student politics. These are Vaka and Röskva. Many local politicians started their careers as members of the council. There are over 60 student unions in operation within the university. Each union is made up of students of a particular subject or a few related ones. Postgraduate students in some fields have their own unions. Membership is optional. A large part of the unions' function revolves around social activities, the most common of which are the so-called "science trips", a tradition where companies and organizations in the industry invite students in a relevant field over for a presentation and drinks. Some postgraduate student unions also organize small-scale academic seminars. Félagsstofnun stúdenta is a self-owned institution that runs several services in and around the campus. These include kindergartens, low-rent apartments, cafeterias and a large bookstore.

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.
