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>
Sausalito Summernight "Sausalito Summernight" is the title of a 1981 U.S. Top 40 hit by Nederpop band Diesel. It was fourth of four singles issued from the band's 1980 debut album Watts in a Tank, the final three of which became chart hits. It was the greatest hit from the LP (U.S. #25). The track became a #1 hit in Canada. It was also their only charting single there. Overview The song was written in 1979 by Diesel members Mark Boon and Rob Vunderink at Boon's parental home in the Hague: (Rob Vunderink quote:) "I came up with the riff, [Boon] added some chords, and then I came up with the melody", the song's tune being completed in roughly an hour's time. The lyrics were written the following day by Boon who in 1962 - at age 11 - had moved to Los Angeles and had lived in California until 1967,, and had also sojourned in California prior to joining Diesel in 1978: Boon would later recall that he had spent time in Sausalito the summer before writing the song. An ironic car ode, the lyrics of "Sausalito Summernight" focus on a couple driving a "clunker" north from Los Angeles to San Francisco who take a breather in Sausalito, four miles from San Francisco (and in fact to its north). In other countries, the track is known as "Sausolito Summernight", as a result of a misspelling on the Netherlands releases of the single and the album. This was corrected on the 1981 U.S. and Canadian releases. Although eventually afforded classic hit status in the Netherlands, "Sausalito Summernight" was only a modest chart success in its original 1980 local release, but did in 1981 became a U.S. Top 40 hit and also reach #1 in Canada: further international releases ensued but - apart from nicking the charts in a Netherlands re-release - with no further success. "Sausalito Summernight" was oft-cited as a Steve Miller Band soundalike: eg. "'Sausalito Summernight' is a top-notch number with power, melody and snap that sounds like the seemingly defunct Steve Miller Band at more than its best" (from Pittsburgh Press 18 October 1981). In fact "Sausalito Summernight" would reach the U.S. Top 40 a week prior to the 23 October 1981 release of Circle of Love, the first non-compilation Steve Miller Band album in four years, with the Top 40 tenure of that album's lead single: "Heart Like a Wheel", overlapping with that of "Sausalito Summernight" for four weeks in November 1981. It was reported in December 1981 that "Sausalito Summernight" had sold 600,000 units worldwide. Netherlands release and reception "Sausolito Summernight" was introduced on Diesel's debut album Watts in a Tank, whose producer Pim Koopman would recall that the recording of "Sausolito Summernight" cost half the budget for the entire album. Watts in a Tank had been recorded in 1979 subsequent to the band's first single: "Goin' Back to China", reaching #34 on the [Netherlands] Single Top 50: upon the album's March 1980 release - by which time the advance single: "Down in the Silvermine", had charted at #16 - Koopman and the band members all considered "Sausolito Summernight" the obvious choice for single release:however Diesel's label Polydor chose another album cut: "Alibi", and only after "Alibi" proved a flop did Polydor give single release to "Sausolito Summernight" - edited to 3:30 from the 5:06 album track - which afforded the group a modest chart comeback peaking at #33. The track's U.S. Top 40 success in the autumn of 1981 - see Section 3 below - would occasion its re-release in the Netherlands, with 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.
