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>
Les mariés de la tour Eiffel Les mariés de la tour Eiffel (The Wedding Party on the Eiffel Tower) is a ballet to a libretto by Jean Cocteau, choreography by Jean Börlin, set by , costumes by Jean Hugo, and music by five members of Les Six: Georges Auric, Arthur Honegger, Darius Milhaud, Francis Poulenc and Germaine Tailleferre. The score calls for two narrators. The ballet was first performed in Paris in 1921. Background The ballet had its genesis in a commission to Jean Cocteau and Georges Auric, from Rolf de Maré of the Ballets suédois. Cocteau's original title for his scenario was The Wedding Party Massacre. It has been suggested that Raymond Radiguet, the young writer close to Cocteau at the time, made some contribution to the libretto. Running short of time, Auric asked his fellow members of Les Six to also contribute music, and all of them did except Louis Durey, who pleaded illness. It was staged by the Ballets suédois at the Théâtre des Champs-Élysées in Paris on 18 June 1921, the principal dancers being C. Ari, J. Figoni, and K. Vahlander. The orchestra was conducted by Désiré-Émile Inghelbrecht. The narrators were Jean Cocteau and Pierre Bertin. It had a brief moment of fame and even scandal, but then fell into oblivion, although it was given in New York City in 1923. A new production opened there in 1988. Story The story of the ballet is somewhat nonsensical: The new couple have a wedding breakfast on Bastille Day (July 14) at a table on one of the platforms of the famous tower. A guest makes a pompous speech. When a humpbacked photographer bids everyone to "watch the birdie," it appears that a telegraph office suddenly springs into existence on the platform. A lion comes in and eats one of the guests for breakfast and a strange figure called "a child of the future" appears and kills everybody. Nevertheless, the ballet concludes with the end of the wedding. When asked what the ballet was about, Cocteau replied: "Sunday vacuity; human beastliness, ready-made expressions, disassociation of ideas from flesh and bone, ferocity of childhood, the miraculous poetry of everyday life." On 29 July 1923, in a letter, Francis Poulenc described the work as "toujours de la merde ... hormis l'Ouverture d'Auric" ("yet more shit ... apart from Auric's Overture"). The ballet The sections of the ballet are: Overture (14 July) - Georges Auric Marche nuptiale - Darius Milhaud Discours du General (Polka) – Francis Poulenc La Baigneuse de Trouville – Poulenc La Fugue du Massacre – Milhaud La Valse des Depeches – Germaine Tailleferre Marche funèbre – Arthur Honegger (in which he quotes the Waltz from Gounod's Faust) Quadrille – Tailleferre Ritournelles – Auric Sortie de la Noce – Milhaud. Recordings The score was unpublished until the first full recording of the work in 1966, which was supervised by Darius Milhaud. The ballet has also been recorded more recently by the Philharmonia Orchestra under Geoffrey Simon. In 1987, Marius Constant arranged the music for an ensemble of fifteen instruments: wind quintet, string quintet, trumpet, trombone, harp and two percussion. This version of the music has been recorded by the Erwartung Ensemble under Bernard Desgraupes, with Jean-Pierre Aumont and Raymond Gerome, narrators.

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.
