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>
Al Cisneros Al Cisneros (born September 23, 1973) is an American musician from San Jose, California. He is the singer and bassist for the stoner metal band Sleep. He is also the singer and bassist in the rhythm heavy drone band OM. He was a member of Shrinebuilder and Asbestosdeath and has put out six releases as a solo artist. On April 20, 2019, Rickenbacker Guitars announced the release of a limited edition Al Cisneros signature bass guitar, Rickenbacker model number 4003AC. Music career Cisneros' earliest musical interests included an appreciation of Black Sabbath, in particular their first four albums. In 1989 he formed the sludge metal band Asbestosdeath, taking up bass and vocal duties, with Chris Hakius on drums and Matt Pike and Tom Choi on guitar. Asbestosdeath released two EPs in 1990. Sleep Following Choi's departure, Cisneros, Hakius and Pike recruited Justin Marler on guitar and renamed themselves Sleep. Cisneros jokingly called himself "Luke" in the early days of Sleep, in homage to 'Luke's Wall', the title of the outro section of War Pigs. In 1991 Sleep released their first album, Volume One. They soon gained a devoted underground following in the doom metal scene. In 1992 they released their next album, Sleep's Holy Mountain an influential album in the early development of stoner metal. Between 1995 and 1998, Sleep worked extensively on their next album, Dopesmoker, a single song lasting one hour. However, their record label at the time refused to release it, and in 1998 Sleep disbanded. An abridged form was released in 1999 under the title Jerusalem. Dopesmoker in its entirety was first officially released by Tee Pee Records on April 22, 2003. On November 26, 2012, it was reported that Sleep had recently announced their own status as a "full, reunited band". OM In 2003, Cisneros and Hakius decided to form their own band named OM, with Cisneros on bass and vocals and Hakius on drums. As a duo OM released the albums Variations on a Theme in 2005, Conference of the Birds in 2006, and Pilgrimage in 2007. In January 2008, Hakius decided to leave the band and was replaced by Emil Amos on drums. Since then, OM has released the two full-length studio albums God is Good and Advaitic Songs on the Drag City label, a 7" for Sub Pop entitled Gebel Barkal, and the live vinyl-only LP Conference Live on Important Records. OM's 2012 tour for the Advaitic Songs album included Robert Lowe on backing vocals, guitar, synthesizer and tambura. Lowe had previously appeared on vocals and tambura on God Is Good. Solo In December 2012 Cisneros released his first solo record Dismas on the band's own Sinai imprint, following the religious tones themed in OM but with more of a dub approach. A second solo record Teresa of Avila followed in March 2013. A 10" EP featuring two longer songs, "Ark Procession" and "Jericho", was also released in 2013. In January 2014 a 12" EP featuring five songs was released and in October 2014 a 7" featuring two songs and artwork by David V. D'Andrea will be released by Samaritan Press. Another 7" on the Sinai imprint followed the next month under the title "Lantern of the Soul".

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.
