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>
Duncan McGuire Duncan Hazlett McGuire (died 10 July 1989), was an Australian musician, songwriter, recording engineer and producer. He was associated with vocalist, Doug Parkinson, in various groups during the 1960s and 1970s; McGuire was also a founding member of the jazz fusion band, Ayers Rock from 1973 until he left in 1976. As a bass guitarist he appeared in several of Parkinson's groups including The Questions (1965–68), Doug Parkinson In Focus (1968–1969) and The Southern Star Band (1978–81). He went into music production in the early 1980s, in October 1980 he co-produced and engineered the debut self-titled album by Australian rock band, INXS. He died of a brain tumour in July 1989. Early life and career Duncan McGuire's music career began in 1959 with his first band, The Phantoms, in Sydney. By 1963, on bass guitar, he had joined Roland Storm and The Statesmen, which included Storm on lead vocals, Mike Allen on drums, Peter Maxworthy on lead guitar, and Mark Rigney on drums. They recorded two singles, "It's the Stomp" (1963) and "The Swingaroo" (1964) for HMV Records. Without Storm, The Statesmen also recorded two of their own singles for HMV, "Beach Comber" (1963) and "Slow Stompin'" (1964). In 1964, band member Rigney left The Statesmen and Billy Green (aka Wil Greenstreet) joined on guitar as the group became Roland Storm and The Epics, which recorded a single, "Zip a Dee Doo Dah" (1964), and then became simply known as The Epics when Storm also left. The Epics also issued their own singles, "Caravan" (September 1964) and "Too Late" (June 1965). As a member of The Statesmen or The Epics, McGuire backed Little Pattie live, as well as on her early singles and her first album, as well as backing other artists including Reg Lindsay, Johnny Ashcroft, Bryan Davies, Jay Justin and Johnny O'Keefe. Bands - The Question and Doug Parkinson From late 1965 to 1968 McGuire was the bass guitarist, alongside Green on guitar, in The Questions, which were a "musically substantial bunch" and they released their debut album, What Is a Question?, in October 1966. Australian musicologist, Ian McFarlane, described it as containing "sub-Herb Alpert pastiches [which] failed to chart". Early in 1967 Doug Parkinson joined on lead vocals, it was his first major band, the line up also included Ray Burton on guitar and Doug Lavery on drums – both later joined The Valentines and Axiom – and Rory Thomas on Hammond organ. The Questions entered the 1967 Hoadley's Battle of the Sounds and won the New South Wales state final, they competed in Melbourne for the Australian final finishing second to The Groop. McFarlane described The Questions' first three singles with Parkinson as "minor psychedelic pop classics": "Sally Go Round the Roses" (July 1967), "And Things Unsaid" (October) and "Something Wonderful" (February 1968). By January 1968 McGuire and Green had left the group. In March 1968 McGuire and Green returned to work with Parkinson for another group, Doug Parkinson In Focus, which also included Lavery and Thomas. That group also won the New South Wales state final of the Hoadley's Battle of the Sounds, and finished third nationally: behind The Groove and The Masters Apprentices. McGuire, as a member of Doug Parkinson In Focus, shifted to Melbourne where the band "were perfectly in sync with the tempo of the times ... [they] became one of the most popular outfits on the Melbourne suburban dance / inner-city discotheque circuit". In May 1969 they issued a cover version of The Beatles' track, "Dear Prudence", which reached No. 5 on the Go-Set National Top 40 singles chart.

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.
