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>
2013 Isle of Man TT The 2013 Isle of Man TT Races were held between the Saturday 25 May and Friday 7 June 2013 on the 37.73-mile Isle of Man TT Mountain Course in the Isle of Man. The event celebrated the 90th anniversary of the first Sidecar TT with a special parade lap for racing sidecar outfits. The 2013 Isle of Man TT Festival also included the Pre-TT Classic Races on 24, 25 & 27 May 2013 and the Post-TT Races on 8 June 2013 and both events held on the Billown Circuit. The Blue Riband event of race meeting the Senior TT race was won by John McGuinness and raising his tally of victories to 20 Isle of Man TT wins and also breaking the outright course record in the Superbike TT with a lap at an average speed of 131.671. The event was dominated by Michael Dunlop winning the Superbike TT race, Supersport TT Races 1 & 2, the Superstock TT and the Joey Dunlop TT Championship with 120 points from John McGuinness and Bruce Anstey in third place. The Sidecar TT race produced a maiden Isle of Man TT wins for the two former Sidecar World Champions with Tim Reeves / Dan Sayle winning Sidecar TT Race 1 and Ben Birchall / Tim Birchall winning Sidecar TT Race 2. The Lightweight TT for 650cc twin-cylinder motor-cycles produced another maiden win for James Hillier and Michael Rutter scored a hattrick or wins in the TT Zero class for electric powered motor-cycles after winning for the third consecutive year. The Senior TT race was red-flagged on the first lap after Isle of Man TT newcomer Jonathan Howarth crashed at the bottom of Bray Hill and 10 spectators were injured in the incident. Practice Week The first part of practice week was dominated by inclement weather with Monday and the Wednesday evening practice run as untimed sessions. The Tuesday session cancelled due to heavy rain showers and the Friday evening was session red-flagged for 50 minutes for the Isle of Man Fire Service to attend a house fire in Kirk Michael village. To provide sufficient practice for competitors the first part of Saturday race day was run as an extended practice session. The first race of the 2013 Isle of Man TT races was the rescheduled Sidecar TT Race 1 and the Superbike TT held over to next day and run on Sunday afternoon for the first time since 2005. The Japanese competitor Yoshinari Matsushita crashed fatally at Ballacrye Corner near Ballaugh during the Monday evening practice causing the session to be abandoned.

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.
