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>
Partisan film Partisan film (, партизански филм) is the name for a subgenre of war films made in FPR/SFR Yugoslavia during the 1960s, 1970s and 1980s. In the broadest sense, main characteristics of partisan films are that they are set in Yugoslavia during World War II and have Yugoslav Partisans as main protagonists, while antagonists are Axis forces and their collaborators. Definition and scope There are disagreements, even among the film critics, about the exact definition of the genre. Partisan films are often equated solely with the populist, entertainment-oriented branch of the genre, characterized by epic scope, ensemble casts, expensive production, and emotionally intense scenes, all introduced into Yugoslav war films by Veljko Bulajić's Kozara (1962). The other branchmuch less interesting to the Communist establishmentwas represented by modernist films, ranging from the poetic naturalism of the Yugoslav Black Wave to experimental stream-of-consciousness films. By the 1980s, economic hardship in the country, as well as change in the ideological landscape, particularly with the younger Yugoslav generation, caused a waning of interest in the genre, and the critical and commercial failure of Bulajić's Great Transport (1983) is usually seen as a symbolic end of the partisan film era. In his analysis of Fadil Hadžić's The Raid on Drvar (1963), Croatian film critic Jurica Pavičić identifies seven key characteristics of what he calls "super-Partisan films": Focus on crucial, well-known, "textbook" examples of Partisan struggle, such as major battles and operations, which are then given an officially sanctioned interpretation. Absence of authentic, high-profile figures of Partisan struggle, with the exception of Josip Broz Tito. In Pavičić's view, the rationale for this was to avoid threatening Tito's cult of personality. Mosaic structure in which sometimes dozens of characters take part, and their fate is followed throughout the film. These characters represent different classes or walks of life (intellectuals, peasants), or different ethnicities. Mixing of the comic with the tragic. The presence of foreign (non-Yugoslav) characters as arbiters. Their role is to witness and verify the martyrdom and heroism of Yugoslav peoples as Partisan films depict them, sending a symbolical message ("There it is, the world acknowledges us as we are"). The characteristic treatment of the Germans: although they are portrayed as villains, and are demonized in various ways, they are also shown to be superior in power and discipline, and are depicted as an efficient, sophisticated, even glamorous adversary. Deus ex machina endings, in which the Partisans break out of seemingly hopeless situations. Pavičić's analysis was criticized for not being universally applicable to Partisan films, and a number of notable exceptions to the above formula were provided.

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.
