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>
Louis Dolivet Louis Dolivet born as Ludovici Udeanu (March 26, 1908 – August 1989) was an émigré writer, editor of Free World, film producer, and alleged Soviet spy born in Austria-Hungary, who later obtained French citizenship. From 1942–1949, he was married to Academy Award and Tony Award winning actress Beatrice Whitney Straight, of the prominent American Whitney family. Early life Ludovic Brecher was born on March 26, 1908 in the Austro-Hungarian village of Újradna, Beszterce-Naszód County, now Șanț, Bistrița-Năsăud County, Romania. He became known as Louis Dolivet upon arriving in New York on January 6, 1939. Dolivet claimed to have fought for the French Air Force against the Nazis, before escaping to Manhattan sometime either just before or after the Fall of France in June 1940. The Pittsburgh Press reported that Dolivet, "on crutches because of a leg injury received shortly after France capitulated," spoke to a local gathering of the Foreign Policy Association in May 1941, where "the former French air gunner painted a sorrowful picture of conditions in occupied France." On the same occasion, Dolivet described injuring himself not in battle, but rather in a shipboard fall en route from Europe. Career Free World During its existence from 1941 until 1946, Dolivet was the editor of Free World, a monthly magazine of the International Free World Association, published by Free World, Inc. in New York City. Free World was militantly anti-Fascist, articulating the perspective of left-liberal Popular Front intellectuals and international political figures who supported the Allies in World War II and championed the creation of the United Nations as a successor to the failed post-World War I League of Nations. Following the final issue of Free World in December 1946, Dolivet launched a new magazine called United Nations World, its first issue appearing in February 1947, which he eventually abandoned in 1950, having returned to France in 1949, and subsequently being banned from reentering the United States upon suspicion of having ties to Communism. United Nations World lasted under different editorship until 1953. Film and television Dolivet and his wife, an actress, frequently had Orson Welles and his wife Rita Hayworth over as guests when they lived at Dorothy Whitney Straight Elmhirst's Old Westbury, Long Island estate. Dolivet was said to have mentored Welles politically, and the two men developed a close friendship that began in the early 1940s. Dolivet and Welles collaborated on several projects, most notably the 1955 six-episode British television series Around the World with Orson Welles, and the film Mr. Arkadin, released that same year in Spain. A dispute over the making of Mr. Arkadin led to a falling-out between Welles and Dolivet. Dolivet was reportedly trying to groom Welles for a political career, including a bid for the Senate in Wisconsin or California; or internationally as Secretary-General of the United Nations. Welles was brought on as an associate editor of Free World. Dolivet's influence was such that Welles was soon "making speeches at Free World dinners and functions and to politicians in Washington," as recounted by former KGB agent Alexander Vassiliev, co-author (with Allen Weinstein) of The Haunted Wood: Soviet Espionage in American—The Stalin Era (1999), and (with John Earl Haynes and Harvey Klehr) Spies: The Rise and Fall of the KGB in America (2009). HUAC investigation In the 1950s, an "extensive investigation" was conducted of Dolivet by the House Un-American Activities Committee (HUAC). Dolivet was listed in a 1950 American Friends Service Committee (AFSC) bulletin as, among other things, 'an international roving correspondent for the New York Post,' Karl Baarslag, former Director of Research for HUAC, referred to the Congressional Record

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.
