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>
Ano hata o ute (Filipino: Liwayway ng Kalayaan) aka Dawn of Freedom, aka Fire on that Flag: The End of Corregidor is a 1943 black-and-white Japanese film directed by Yutaka Abe and Gerardo de León. Synopsis Opening credits starts as the narrator speaking about in December 8, 1941 Japan, is accepting the challenge of the Western powers rises in arms after having had to stand by for years watching rapacious America and Britain tread upon the enslaved peoples of East Asia . Japan expeditionary forces are rushed to various places in the vast areas of Greater East Asia in order to drive out the Western powers. The first blow in the Philippines is death when Nippon warplanes raid Clark Air Base and Iba airfield on December 8. The story of the Japanese victory at the Battle of Corregidor and the U.S. military's hasty retreat from the islands. The film presented the Japanese as Asian liberators who came to free the Filipinos from decades of colonial oppression at the same time Sub corporal Ikejima (Heihachiro Okawa) helped the boy named Toni (Ricardo Pasion) which is a younger brother of Capt. Garcia (Fernando Poe Sr.) to walk again after a car accident. About the Film The film was premiered in Tokyo on February 5, 1944. Originally entitled Mito Sakusan (Philippine Operation), it was changed to Ano Hatte O Utte or literally, “Tear down the Stars and Stripes.” For the Philippines, it was decided to use The Dawn of Freedom or Liwayway ng Kalayaan. The making of the movie had gone into controversies such as, using Filipino and American POW's as extras along with the Filipino which is invited or coerced them into work along with the Japanese actors specially in the scene where the photograph under the ad copy shows two Japanese soldiers holding a group of Filipinos at bay under gun point. Without seeing the film, one would not know the Filipinos were thieves caught by vigilant Japanese soldiers protecting the local population. Whether wittingly or not, the advertisement throws the terms of this "co-production" into question, This was how the Japanese producers formed the all-star cast and crew for The Dawn of Freedom. The Dawn of freedom is most effective Japanese films from the Pacific War, however, the historian is always hard-put to research how a film was received upon its release. The documents available as avenues to the past are difficult to trust. and there is always some measure of speculation mixed with one's analysis. Our approach to The Daunt of Freedom's spectators in the past might take three very different paths: film criticism, studio records, and the film itself.

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.
