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>
Amrutha Varshini Amruthavarshini is a 1997 Indian Kannada romantic drama film written, photographed and directed by Dinesh Baboo. It features Ramesh Aravind, Suhasini and Sharath Babu in the lead roles with Nivedita Jain appearing in a cameo role. It features Ramesh Arvind playing a negative role for which he was widely praised. The film revolves around the three central characters of a husband (Sharath), wife (Suhasini) and a friend (Ramesh) who intrudes into the couple's life and turns their life into tragic events. The film was produced by Bharathi Devi under the banner Chinni Chitra. Upon release, the film was declared a musical blockbuster hit with all the songs of the soundtrack composed by Deva becoming evergreen hits. The songs of the film continue to be favorites among the Kannada audience. The film was one of the highest grossers at the box-office for the year 1997. The film was awarded with multiple State Awards and Filmfare Awards, particularly for the story and acting. The film was subsequently dubbed in Telugu with same title name and in Tamil as Uyirinum Melaaga. In Malayalam, the film was remade as Mazhavillu (1999) by the same director. Plot Hemanth (Sharath Babu) and Veena (Suhasini) are a happily married couple with Hemanth working for an advertisement firm. One day, Abhishek Bharadwaj (Ramesh Aravind), a poet and Hemanth's childhood friend, visits them. Abhishek is depressed due to the death of his girlfriend, Shruti (Nivedita Jain) due to cancer. Shruthi had made Abhishek promise that he will marry another girl after her death. Abhishek becomes obsessed with Veena as she has a strong resemblance to Shruthi. Hemanth comes to know about this but doesn't reveal this to Veena. He takes Abhishek to a cliff and ask him to change his mind and go back home but Abhishek tries to kill him by letting their jeep hit him which causes him to fall off the cliff. Abhishek does not try to save him even though he could have, when Hemanth was hanging off the cliff. Hemanth's automatic camera captures the whole episode. When Veena accidentally sees those pictures, she understands what really happened that day. She pretends to have moved on and suggests that she is ready to share her life with Abhishek. She asks him to take her to the cliff where Hemanth died as it was his long cherished dream to take photos from the cliff. She confronts him, revealing that she knows what had happened and shows him those pictures of that day. She then commits suicide from that cliff, in front of Abhishek, as a revenge.

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.
