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>
making it to the final where he defeated Tomohiro Ishii to win it. After winning the tournament, Takaiwa revealed to the fans in Korakuen Hall that he was actually Zainichi Korean, and said that while he was proud to be Korean, he was also proud to be able to say he was born and raised in Japan, which prompted loud cheers from the audience. On May 16, Takaiwa defeated Tony Stradlin to win the International Junior Heavyweight Championship. Shortly after, Takaiwa formed a tag team with Ishii, and the two defeated Leonardo Spanky and Low-Ki to win the NWA International Lightweight Tag Team Championship. Ishii and Takaiwa continued to defend the championships until September, when they were defeated by Spanky and Kaz Hayashi. Despite losing the tag team championships, Takaiwa continued to successfully defend the Junior Heavyweight Championship throughout 2004, defeating the likes of Minoru Fujita, Jun Kasai, Super Crazy and Spanky. On October 17, Takaiwa's match against Naohiro Hoshikawa was stopped early after Hoshikawa was legitimately knocked unconscious and fell into a coma after taking a powerbomb from the top of the cage by Takaiwa. Takaiwa would go on to hold the championship until December, when he was defeated by Super Crazy. On June 24, 2006, Takaiwa defeated Katsuhiko Nakajima to win the WWA World Junior Light Heavyweight Championship, and on July 27 defeated Takuya Sugawara to unify both the WWA and International Junior Heavyweight titles. In February 2007, while simultaneously holding the WWA, International and GHC Junior titles, Takaiwa beat Ikuto Hidaka to win the AWA World Junior Heavyweight Championship. After 7 years with the promotion, Takaiwa announced he was leaving Pro Wrestling Zero1 Max to become a freelancer on December 17, 2008. Return to NJPW/Black Tiger (2008–present) Takaiwa competed in his first Best of the Super Juniors tournament since 2000 in June 2008, finishing with four points and failing to advance. After going freelance in December 2008, Takaiwa debuted as the fifth Black Tiger on February 15, 2009, breaking the Black Tiger tradition of foreigners under the mask, by attacking Tiger Mask. On June 20, 2009, at Dominion 6.20 Tiger Mask defeated him in a mask vs. mask match and afterwards Takaiwa revealed his identity by removing his mask. Takaiwa lost his mask as Black Tiger V for the second time on May 14, 2011, when he was defeated at a Toryumon Mexico event by Último Dragón. Despite losing his mask twice, Takaiwa continues to make appearances as Black Tiger V. Pro Wrestling Noah (2001–2007, 2011–2014) Shortly after the formation of Zero1, Takaiwa also began making appearances in Pro Wrestling Noah, and in October 2001 defeated Yoshinobu Kanemaru to win the GHC Junior Heavyweight Championship. Takaiwa held on to the title until December, when he dropped it to Naomichi Marufuji. Takaiwa returned to Noah in 2003 to take part in the Differ Cup, a tag team tournament featuring junior heavyweights. Teaming with Zero1 trainee Yoshihito Sasaki, they made it to the finals where they were defeated by Toryumon representatives Ultimo Dragon and Yossino. On December 23, 2006, Takaiwa won the championship a second time, defeating Takashi Sugiura at a SEM event. He held the title until April 2007, dropping it to Mushiking Terry. Takaiwa returned to Noah again in 2011, taking part in the NTV G+ Cup Junior Heavyweight Tag League with his trainee Osamu Namiguchi. The two performed poorly, earning just two points and failing to advance. Takaiwa made another one off return to Noah in December 2013, unsuccessfully challenging Taiji Ishimori for the GHC Junior title. Freelancing (2009–2017) Originally aiming to step away from pro

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.
