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:

investigations. Corbu also claimed Saunière had in 1892 discovered "parchments" whilst renovating his church "written in a mixture of French and Latin, which at first glance could be discerned passages from the Gospels". It has been noted by critics however that Saunière began renovating his church in 1886, not 1892, and that "there was no evidence that these parchments had ever existed". Corbu claimed that Marie Dénarnaud would confide a secret to him before she died, saying "Pray do not worry yourself, Monsieur Corbu. You shall have more money than you will be able to spend!" Corbu provided a tape-recording of his story for his guests, a transcript of which was deposited in the Archives de l'Aude, Carcassonne on 14 June 1962 by Maurice Tous of Alet-les-Bains. Corbu's story inspired author Robert Charroux to develop an active interest and in 1958, with his wife Yvette and other members of The Treasure Seekers' Club (that he founded in 1951), scanned the village of Rennes-le-Château and its church dedicated to Saint Mary Magdalene for treasure using a metal detector. The Dowsing-by-Pendulum enthusiast and hypnotist Rolland Domergue, with medium Germaine Goyard, joined Corbu in 1958 to look for the treasure, and thus began the extensive accumulation of pilgrimages to the site by many various people from all over France, that on 28 July 1965 forced the local Municipal council to introduce a local By-law prohibiting excavations in the village. In April 1961, the French Television Channel RTF made a documentary directed by Marina Grey entitled La Roue Tourne ("The Wheel Turns"), that cast Noël Corbu as Father Saunière. Corbu then changed his story about Saunière on an interview for the France Inter radio programme to Robert Charroux in 1962, dropping all references to Blanche of Castile and claiming that Saunière's alleged treasure discovery relied upon two alleged inscriptions discovered in 1928: one on a gravestone in the cemetery and another on a stone found on farmland property close to Rennes-le-Château (Corbu alleged both "artifacts" were discovered by a retired amateur archaeologist, Ernest Cros, who died in 1946). In the revised edition of his book Treasures of the World published during the 1970s (not translated into English), Robert Charroux added the material given in the 1962 radio interview, but also retained parts of the original chapter on Rennes-le-Château that mentioned Blanche of Castile. These references to inscriptions by Corbu inspired two documents of unknown provenance called Recherches de Mons. L'Ingenieur en chef Ernest Cros; entreprises dans la Haute Vallée de l'Aude, surtout durant les années 1920 à 1943, commonly called "The Cros Report" (one of them is said to have originated on Corbu's typewriter, the other is attributed to René Chesa). Priory of Sion hoax Noël Corbu's account of the discovery of the parchments by Father Saunière was later quoted in the document Un Trésor Mérovingien à Rennes-le-Château (1966) attributed to "Antoine L'Ermite", that for "stylistic reasons suggest that this was written by Pierre Plantard and/or Philippe de Chérisey". Philippe de Chérisey confessed to having forged the famous parchments that appeared in Gérard de Sède’s 1967 book, L'Or de Rennes (as well as faking "The Cros Report") in his manuscript "Stone and Paper". The text of the document attributed to "Antoine L'Ermite" was modelled on Charroux's account found in his book, Trésors du Monde, where he extensively quoted Noël Corbu. Heritage, tourism and archaeology Noël Corbu sold the Saunière estate in 1964 to Henri Buthion (1924–2002) and moved to the Château of Saint-Félix-Lauragais which he recently acquired. On 20 May 1968, on his way to Fanjeaux from Montpellier, Corbu's car, a Renault 16 was

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.
