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>
for the yeshiva. Growth of the Mir When Reb Finkel first came to the Mir at the age of 17 in 1960, enrollment was less than 200 students, of which 75 percent were avreichim (married students) and 25 percent were undergraduates. When he became rosh yeshiva in 1990, enrollment stood at approximately 1,200 students. At the time of his death, enrollment reached nearly 6,000 undergraduates and over 1,600 avreichim. This growth is credited to Finkel's open-door policy as rosh yeshiva: whoever wished to learn at the Mir was welcome. Enrollment now includes Litvish, Hasidic, Ashkenazi, Sephardi and baalei teshuva students from Israel, the United States and Europe. To accommodate the ever-increasing enrollment, Finkel fund-raised for and constructed four new buildings in addition to the original yeshiva building constructed by Reb Leizer Yudel in 1949. He assigned separate battei medrash (study halls) for each group of students, making one for Israeli students, one for Americans, one for those who wished to study without a daily shiur, and so on. As enrollment continued to climb, several students of the main maggidei shiur (lecturers) began delivering shiurim in English, and Finkel raised the funds to open a new beis medrash in 2006 for these shiurim too. Yet another beis medrash was built in recent years. The Mir also opened a yeshiva gedola for Israeli students in the Brachfeld neighborhood of Modi'in Illit where Finkel gave shiurim and occasional shmuessen (musar talks), and a yeshiva ketana in the Ramat Shlomo neighborhood of Jerusalem. In an unusual move for a Litvish yeshiva, Finkel accepted 800 Hasidic students and allowed them to learn in their own chabura and follow their own customs, including a fartug (pre-dawn study session) before morning prayers. This group, known as Chaburas Ameilim BaTorah (the "Toiling in Torah" Study Group), was housed in a different neighborhood, but the week before his death, Finkel moved them onto Mir yeshiva premises. He participated in their Thursday-night study sessions as well as their seudot mitzvah (festival meals) marking a siyum, and Hanukkah parties.<ref name="hamodia">"Hagaon Harav Nosson Tzvi Finkel, zt"l: Leader of thousands, rebbi to each one". Hamodia, 10 November 2011, pp. A20, A26.</ref> Notwithstanding the Mir's huge enrollment, Finkel tried to remember the name of each student. He also remembered personal details about each of his alumni and donors abroad. His brother-in-law, Rabbi Aharon Lopiansky, rosh yeshiva of the Yeshiva of Greater Washington, said that at Mir dinners, 1,000 people could be waiting to speak with the rosh yeshiva, "and almost every single one on the line was someone he had had a personal connection with". Despite his busy schedule, Finkel also expressed a willingness to learn in chavruta with any student who asked. It was estimated that he studied with approximately 80 people every week. Like his great-uncle Reb Leizer Yudel, Finkel offered cash incentives for Torah study, challenging his students to learn many pages of Talmud and study for large blocks of time. He regularly hosted siyums for students in his own home and at his own expense. Finkel shouldered the responsibility for raising funds for this giant Torah enterprise. Despite his disease and its side effects, he traveled twice a year to England and the United States. In the past two years, the economic recession saw the yeshiva's debts mounting quicker than they were being met, with salaries and kollel stipends running months behind. Finkel was said to be very upset by this state of affairs. Illness Reb Finkel was diagnosed with Parkinson's disease in the late 1980s. Though he experienced much difficulty in walking and talking, and suffered from involuntary tremors

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.
