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>
recovery system faults with their two GT-R LM Nismos and resume their testing programme in the United States. LMP2 consisted of eight cars with 24 drivers. Starting at the Nürburgring, Strakka Racing switched from running a Dome S103 to a Gibson 015S for the rest of the season. This was so the team could use the Dome S103 for testing and developing in preparation for a planned entry to LMP1 in 2017. OAK Racing pulled their No. 35 Ligier JS P2 Nissan from the entry list for unspecified reasons. Zoël Amberg was withdrawn on medical grounds which were believed to be related from an crash he suffered at the Monaco GP2 Series round three months prior. Amberg's place in the 43 Team SARD Morand Morgan was taken by the International GT Open driver Archie Hamilton. After driving the No. 19 Porsche 919 Hybrid at Spa-Francorchamps and Le Mans, Nick Tandy returned to KCMG for the first time since the season-opening round at Silverstone. The Le Mans Grand Touring Endurance Professional (LMGTE Pro) field consisted of three manufacturers (Aston Martin, Ferrari and Porsche), while the Le Mans Grand Touring Endurance Amateur (LMGTE Am) entrants were six teams: Aston Martin Racing, AF Corse, Larbre Compétition, Dempsey-Racing Proton, Porsche Team Manthley, and SMP Racing. British GT racer Jonathan Adam made his first appearance in the season in the No. 97 Aston Martin Vantage GTE and he was paired with regular drivers Darren Turner and Stefan Mücke. Le Mans outright winner and United SportsCar Championship competitor Earl Bamber returned to the World Endurance Championship to drive the No. 88 Proton Racing Porsche 911 RSR, replacing Klaus Bachler, who had an ADAC GT Masters commitment at the Sachsenring. After fracturing two vertebrae in a heavy accident at Le Mans, Roald Goethe, the co-driver of the No. 96 Aston Martin, was declared fit to compete at the Nürburgring. Preview The 6 Hours of Nürburgring was confirmed as part of the FIA World Endurance Championship's 2015 schedule in an FIA World Motor Sport Council meeting in Doha on 3 December 2014. It was the fourth of eight scheduled endurance sports car races of the 2015 FIA World Endurance Championship, and the inaugural running of the race as part of the championship. It was held on 30 August 2015 at the Nürburgring GP-Strecke circuit in Nürburg, Germany following two days of practice and qualifying. The race was the first world sports car championship round to be held at the circuit since the 1991 430 km of Nürburgring, and took place on a modified version of the sixteen-turn layout which lacked the Veedol chicane. Before the race Audi Sport Team Joest drivers André Lotterer, Benoît Tréluyer and Marcel Fässler led the Drivers' Championship with 80 points, twenty ahead of nearest rival Tandy in second place, and a further two in front of Bamber and the non-competing Nico Hülkenberg. Marc Lieb, Romain Dumas and Neel Jani were fourth on 57 points and Timo Bernhard, Mark Webber and Brendon Hartley followed in fifth position on 53 points. Porsche led the Manufacturers' Championship with 140 points, sixteen points ahead of their rival Audi in second place. The third-placed manufacturer Toyota had scored 71 points and Nissan rounded out the top four but had yet to accumulate any points. Audi dominated the season's opening two rounds and Porsche won the 24 Hours of Le Mans. The trio of Lieb, Dumas and Jani secured two consecutive second-place finishes and their teammates Bernhard, Webber and Hartley placed second at Le Mans. After Le Mans, the FIA Endurance Committee altered the balance of performance in the

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.
