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>
Abu Hatim Muhammad ibn Idris al-Razi Abu Hatim, Muhammad ibn Idris al-Razi (811–890) was a notable hadith scholar born in Ray. He is the father of Ibn Abi Hatim. Life His full name is Abu Hatim Muhammad bin Idris bin al-Mundhir bin Dawud bin Mahran ar-Razi al-Handhali al-Ghatafani. Some sources suggest that he was originally from Isfahan and was a mawla of the Ghatafan tribe. Other sources suggest that he acquired his nisbat from a region of Ray called "Darb Handhala". He died on the month of Sha’bân in the year 277H. His teachers of Hadith The better known [narrators] he narrated from: He narrated from many, such that al-Khalili said, “Abu Hatim al-Labban al-Hafidh said to me, ‘I had gathered [those] who Abu Hatim ar-Razi narrated from; they reached close to 3,000.’” From the better known of them are: Abu Nu’aim al-Fadl bin Dukain Zuhair bin ‘Abbad Yahya bin Bukair ‘Ubaidullah bin Musa Adam bin Abi Iyas Thabit bin Muhammad az-Zahid ‘Abdullah bin Salih al-’Ijli ‘Abdullah bin Sâlih al-Kâtib Muhammad bin ‘Abdillah al-Ansârî Qabîsah Some of his early students The better known narrators [who narrated] from him: Abū Zur’ah ar-Razî Yūnus bin ‘Abdil-A’la Abu Bakr bin Abid-Dunya Musa bin Ishaq al-Ansari Abu Dawood Al-Nasa'i Abu ‘Awanah al-Isfara’ini Abul-Hasan al-Qattân Abū Bishr ad-Dūlâbî Praise The Scholars’ and Imams’ commendation of him: Abū Zur’ah told Abi Hatim, “I have not seen [anyone] more intent on seeking the hadîth than you.” Yūnus bin ‘Abdil-A’la said, “Abu Zur’ah and Abū Hâtim are the two Imams of Khurasan.” He supplicated for them both and said, “Their continuance is an improvement for the Muslims.” Abdur-Rahman bin Abi Hatim said, “I heard Mūsâ bin Is·hâq al-Qâdî saying, ‘I have not seen [anyone] more preserving than your father,’ and he had met Abū Bakr Ibn Abi Shaibah, Ibn Numair, Yahya ibn Ma'in, and Yahya al-Himmani.” Ahmad bin Salamah an-Naisâbūrî said, “I have not seen after Ishaq and Muhammad bin Yahya [anyone] more preserving of the hadîth or more knowledgeable of its meanings than Abi Hatim ar-Razi.” Uthman bin Khurrazadh said, “The most preserving of those I saw are four: Muhammad bin al-Minhal ad-Darir, Ibrâhîm bin ‘Ar’arah, Abu Zur’ah ar Razi, and Abu Hatim.” al-Khalili said, Abū Hâtim was a scholar of the Companions’ differences [of opinion] and the jurisprudence of the Followers and [those] after them. I heard my grandfather and a group [who] heard ‘Ali bin Ibrahim al-Qattan saying, “I have not seen the like of Abi Hatim.” So we told him, “[But] you had seen Ibrâhîm al-Harbî and Isma’il al-Qadi.” He said, “I have not seen [anyone] more complete or more virtuous than Abi Hatim.” Abul-Qasim al-Lalika’i said, “Abū Hâtim was an imam, a hâfidh, a verifier.” Al-Khatib al-Baghdadi said, “Abū Hâtim was one of the credible, hâfidh imams.” Al-Dhahabi said, “He was from the oceans of knowledge. He travelled about the countries and excelled in the text and the chain [of transmission]. He gathered and compiled, disparaged and accredited, authenticated and deemed defective.” He said, “He was one of the notables and from the formidable imams of the People of the Relic … he was a neighbour in the arena of his comrade and relative, Hâfidh Abu Zur’ah.” References Category:Hadith scholars Category:Sunni imams Category:811 births Category:890 deaths Category:People from Rey, Iran

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.
