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>
Edmond Marin la Meslée Edmond Marin la Meslée (5 February 1912 – 4 February 1945) was a French fighter pilot in World War II. He ranks as the 5th highest-scoring French ace of this conflict with 16 aerial victories. Biography Edmond Marin la Meslée was born on February 5, 1912 in Valenciennes, France. After studying law, he took government-subsidized flying lessons at the Morane flight school and gained his license in 1931. At 19, he entered the French Air Force and, after graduating from the school at Istres, was assigned to a unit in Strasbourg. At the end of his two-year tour, he re-enlisted for another two years, despite having to serve at a lower rank. In October 1937, he was admitted to the Air Force Academy and graduated with the rank of 2nd Lieutenant. He was assigned to the GC I/5 fighter group (Reims), to fly one of its 32 Curtiss H-75 fighters. Groupe de chasse are French fighter units approximately equivalent to a two-squadron wing in the British RAF. There he was taught by Jean Accart, who thought highly of his potential as a fighter pilot. During the Battle of France, Marin la Meslée distinguished himself by shooting down 16 "certain" German aircraft, although some sources credit him with as many as 20 including his 4 "probable" ones. On June 1, his leader was wounded and "Marin" replaced him at the head of the first escadrille (approx. a squadron of 12 fighters) of GC I/5. After the armistice, GC I/5 was evacuated to Saint-Denis-du-Sig and later to Rabat, Morocco, but did not see much action against the British. After Operation Torch, French forces in North Africa joined the Allied forces, and Marin la Meslée's unit left for Tafaraoui, Algeria in September 1943 to receive American equipment that eventually materialized as P-39 Airacobras. Marin la Meslée was promoted as CO of his unit, then renamed GC 1/5 "Champagne", on January 9, 1944. The group went back to combat on September 30, 1944, operating from Salon-de-Provence in support of the French and Allied forces pursuing the Germans along the Rhône River, flying mostly ground support missions. On February 4, 1945, near Colmar, Edmond Marin la Meslée was shot down during a strafing attack when his Republic P-47 Thunderbolt suffered a direct hit from a 40 mm anti-aircraft shell (German "Flak"). His aircraft exploded in the crash but his body was nevertheless recovered by the Germans. He had received a piece of shrapnel in the head, and had probably died even before the crash. On February 14, 1953, his name was given to the Reims - Champagne Air Base.

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.
