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>
The Bourne Ultimatum (film) The Bourne Ultimatum is a 2007 American action thriller film directed by Paul Greengrass loosely based on the novel of the same name by Robert Ludlum. The screenplay was written by Tony Gilroy, Scott Z. Burns and George Nolfi and based on a screen story of the novel by Gilroy. The Bourne Ultimatum is the third installment in the Jason Bourne film series, being preceded by The Bourne Identity (2002) and The Bourne Supremacy (2004). The fourth film, The Bourne Legacy, was released in August 2012, without the involvement of Damon, and the fifth film (a direct sequel to Ultimatum), Jason Bourne, was released in July 2016. Matt Damon reprises his role as Ludlum's signature character, former CIA assassin and psychogenic amnesiac Jason Bourne. In the film, Bourne continues his search for information about his past before he was part of Operation Treadstone and becomes a target of a similar assassin program. The Bourne Ultimatum was produced by Universal Pictures and was released on August 3, 2007, and grossed a total of $442 million worldwide becoming, at the time, Damon's highest-grossing film with him as the lead. The film received acclaim from critics, who considered it to be the best film in the series, and praised the performances, action sequences, sound design, story, stunts, camerawork and John Powell's musical score. It was chosen by National Board of Review as one of the top ten films of 2007 and went on to win all three of its nominations at the 80th Academy Awards: Best Film Editing, Best Sound Mixing and Best Sound Editing. Plot Following his pursuit by Kirill, Jason Bourne (Matt Damon) eludes Moscow police while wounded through a train station and deals with more flashbacks of when he first joined Operation Treadstone. Six weeks later, CIA Deputy Director Pamela Landy (Joan Allen) divulges the audiotaped confession of Ward Abbott, the late former head of Treadstone, to Director Ezra Kramer (Scott Glenn). Meanwhile, in Turin, journalist Simon Ross (Paddy Considine) of The Guardian meets an informant to learn about Bourne and Operation Blackbriar, the program succeeding Treadstone. The CIA tracks Ross as he returns to London, after his mention of "Blackbriar" during a cell phone call to his editor is detected by the ECHELON system. Bourne reappears in Paris to inform Martin Kreutz (Daniel Brühl), the brother of his girlfriend Marie Helena Kreutz (Franka Potente), of her assassination in India, also in the previous film. Bourne reads Ross's articles and arranges a meeting with him at London Waterloo station. Bourne realizes that the CIA is following Ross and helps him evade capture for a while, but when he panics and ignores Bourne's instructions, Ross is shot and killed by Blackbriar assassin Paz (Édgar Ramírez) on orders of Deputy Director Noah Vosen (David Strathairn). Vosen's team, reluctantly assisted by Landy, analyzes Ross's notes and identifies his source as Neal Daniels (Colin Stinton), a CIA Station chief involved with Treadstone and Blackbriar. Bourne makes his way to Daniels' office in Madrid but finds it empty. He incapacitates gunmen sent by Vosen and Landy. Nicky Parsons (Julia Stiles), a former Treadstone operative who shares a history with Bourne, tells him that Daniels has fled to Tangier and aids his escape from an arriving CIA unit. Nicky learns that Blackbriar "asset" Desh Bouksani (Joey Ansah) has been tasked with killing Daniels. Vosen sees that Nicky accessed information about Daniels and sends Bouksani after Nicky and Bourne as well, a decision with which Landy fiercely disagrees. Bourne follows Bouksani to Daniels but fails to prevent Daniels's death by a planted bomb.

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.
