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>
Pati Patni Aur Woh (1978 film) Pati Patni Aur Woh () is a 1978 Hindi movie produced and directed by B. R. Chopra. The film stars Sanjeev Kumar, Vidya Sinha, Ranjeeta Kaur, and in guest appearances Rishi Kapoor, Neetu Singh and Parveen Babi. The film was remade under the same name in 2019 starring Kartik Aaryan, Bhumi Pednekar and Ananya Pandey. The film was directed by Mudassar Aziz and produced by Bhushan Kumar. Plot The film starts off indicating the parallels of the story with that of Adam & Eve. Here, Adam is Ranjeet, Eve is Sharda while the apple is Nirmala. Ranjeet is newly employed in a company, whose pay scales can be gauged from the fact that he goes to work on a bicycle. However, this bicycle itself brings him face-to-face with Sharda, when he bumps into her by accident. Sharda's bicycle gets badly damaged & Ranjeet drops her off. The same evening, Ranjeet goes to the wedding of his friend Abdul Karim Durrani (Asrani), a co-worker & a poet. Sharda is also present at the ceremony. Sharda & Ranjeet's love blossoms from there & soon they get married. In the course of a few years, Ranjeet is Sales Manager of the company and father of a son. Sharda & Ranjeet are still living in marital bliss. That is, until Nirmala, Ranjeet's new secretary, shows up. Ranjeet is inexplicably attracted to Nirmala. She is an honest girl who is trying to make two ends meet. She is much more beautiful compared to Sharda. But most of all, she knows nothing about Ranjeet's true intentions & his married life. Ranjeet is initially upset with his thoughts about her, but finally gives in. He carefully plans his further steps. He pretends to be the helpless grieving husband of a cancer stricken wife, who won't live much longer. Nirmala feels sorry for him, thus making it easier for him to get close to her. Nobody, not Sharda, not even his closest friend, suspects a thing. One day, Ranjeet bluffs to Sharda that he will be late coming home as he has a meeting. He takes Nirmala out to dinner. Next day, Sharda finds Nirmala's handkerchief, with lipstick marks on it, in Ranjeet's pocket. She immediately confronts Ranjeet, who makes up a story about a co-worker whose handkerchief he may have accidentally taken. Sharda reluctantly believes him. Ranjeet decides to take his next steps more carefully. Sharda too starts thinking that her fears were unfounded. Ranjeet makes even more interesting back up plans: He prepares two books of poetry, professing his love. The poems are the same in both, only one book contains Nirmala's name, and the other contains Sharda's. Ranjeet courts Nirmala without Sharda's knowledge. The turning point comes when Sharda sees him in a hotel with Nirmala. She later asks him about his meeting, about which the clueless Ranjeet lies. Sharda's fears are confirmed. She starts spying on him & Nirmala, taking incriminating pictures. After sufficient evidence is obtained, she secretly meets Nirmala, posing as a journalist. Nirmala, who hasn't seen Ranjeet's "ailing wife" yet, thinks Sharda intends to blackmail her. But Sharda reassures her that she won't. Nirmala spills all the beans, upon which Sharda reveals her true identity. Meanwhile, Ranjeet gets another promotion & rushes home happily to tell his wife about it. Sharda catches him unawares and lets him know that he is busted. Ranjeet does not know what has hit him. He turns round, only to see Nirmala behind him. Sharda tells him that she is leaving him & the divorce papers will be soon sent

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.
