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>
Nicolas Vatomanga Nicolas Vatomanga Andrianaivo Rakotovao (born 24 September 1975), known as Nicolas Vatomanga is a Malagasy saxophonist, flutist, bandleader and composer. His music combines elements of jazz, blues and traditional musics of Madagascar, including: the hira gasy of the Centre, the beko from the South and the salegy from the North of the Great Island. He is also recognized as one of the heirs of the malagsy flute sodina tradition and of its last great master: Rakoto Frah (Philibert Rabezoza Rakoto). Nicolas Vatomanga has played and/or recorded in Europe, Africa (Senegal and Madagascar), as well as in the United States with: Miriam Makeba, Rakoto Frah, Paco Sery, Eric Le Lann, Regis Gizavo, Solorazaf, Lionel Loueke, Mokhtar Samba, Tony Rabeson, Serge Rahoerson, Linley Marthe, Idrissa Diop, Hanitra Ranaivo, Silo Andrianandraina and Jaojoby Eusèbe. He was invited by Joe Zawinul to play at his concert at the Parc Floral Paris 2002, but he could not honour the invitation. Since 2004, he has lived and performed in Madagascar, where he created the "Vatomanga Band" which appeared for the first time in quartet form during the Madajazzcar Festival 2005 and gradually enlarged to a septet after 2010. In 2011, the band took the name MadaJazz. Biography Early life Vatomanga started with classical music at age four at the National Center for Music education (CNEM) in Antananarivo, Madagascar. He was taught by Mrs Alisera and Seta Ramaroson Andrianary (flutist, saxophonist and composer), both renowned teachers there. Choosing the flute as his first instrument, Vatomanga continued training with Seta at the Cercle Germano-Malagasy (CGM) of Antananarivo. A precocious child, he composed for piano at age eight and played frequently in classical concerts (NCCM, CGM) from age ten. His mother, he claimed, had a great influence on his tastes and his passion for music: classical music, blues, gospel and traditional Malagasy music (such as the hira gasy, the Kalon'ny Fahiny, Ny Antsaly, Rakotozafy and Rakoto Frah in particular); she learned to play valiha (the Malagasy bamboo zither) when he started on flute. Jazz At age fourteen, at Seta's invitation, Vatomanga attended a concert given by American saxophonist and flutist of Caribbean origin, TK Blue (Talib Kibwe). Following the concert, he learned on the flute, from ear and by heart, the theme and the solo of "Pinnacle of Joy" of the album Egyptian Oasis (1987) of the American jazzmen. He, therefore, decided to learn the saxophone and a new form of expression for him: improvised music. Seta, also a jazz saxophonist, taught him jazz basics, especially harmonization of improvisation. Further encouraged by Silo Andrianandraina (also a young Malagasy jazzman), a friend from second class in high school, Vatomanga listened and explored the world of jazz fundamentals, particularly through the works of Charlie Parker, Miles Davis, George Shearing, Oscar Peterson, Sonny Rollins, Stan Getz, Bill Evans, McCoy Tyner, Herbie Hancock, Wayne Shorter, Joe Zawinul and John Coltrane. "Trane" in particular became a great influence. Attuned to his African roots, he listened to South African jazz, including Makeba, Hugh Masekela and Bheki Mseleku. At age fifteen, he began learning the saxophone in a band with Solomiral, an Antananarivo jazz fusion band, then informally with Toty Band and a more traditional music group from Southern Madagascar, Tsimihole. In 1992, he participated in his first Madajazzcar Festival, accompanied by an informal group created for the occasion. Bassist Olver "Toty" Andriamampianina became Vatomanga's second mentor. Seta and Toty provided him constant encouragements to pursue a musical career. Throughout the years of his BSc diploma, he attended the Jazz Club of Mahamasina, founded by pianist and composer Sammy Andriamanoro.<ref>Anjara Rasoanaivo, "Sammy Andriamanoro: a

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.
