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>
In the second rubber of the first zonal tie against China, Tomic was victorious against Wu Di. In the second zonal tie of 2012, he recorded two straight sets victories in a 5–0 rout of South Korea. In the 2012 Davis Cup World Group Playoffs, Tomic was victorious in his first rubber against Cedrik-Marcel Stebe in four sets but fell to Florian Mayer in straight sets which would see Australia lose to Germany 3–2 overall. Following poor off court behaviour in late 2012, Tomic was suspended from playing for Australia in the first round of the 2013 Davis Cup competition. After serving a one tie ban, Tomic returned to the Australian Davis Cup team in their 2013 zonal semifinal against Uzbekistan and later that year was instrumental in Australia's return to the World Group after an away playoff victory over Poland. Injuries prevented Tomic from competing in the Davis Cup competition in 2014 but he returned for Australia's first round of the 2015 Davis Cup against the Czech Republic. Despite facing the two-time defending champions away, Tomic secured two crucial singles victories and led Australia to a 3–2 victory over the Czech Republic. It was the first time Australia had reached the second round of the Davis Cup world group since 2006. Tomic was then once again suspended from the Australian Davis Cup team for an outburst during a Wimbledon press conference. Tomic returned to the team once again in the 2015 semifinal against Great Britain and scored a crucial four set victory over Dan Evans in the second rubber. Tomic played for Australia at the 2016 Davis Cup where they faced the United States. He won his first match against Jack Sock in four sets. However, he lost the reverse singles to John Isner which meant Australia lost in the first round. Olympics (0–1) Tomic represented Australia in his maiden Olympics at London 2012. He competed in the singles competition against Japan's 15th seed Kei Nishikori in the first round, but fell in two straight tiebreaks. Hopman Cup (5–1) At the 2013 Hopman Cup Tomic defeated Tommy Haas (7–6, 3–6, 7–5), World No. 1 Novak Djokovic (6–4, 6–4) and Andreas Seppi (6–3, 7–5). Australia finished in 2nd place in the group. At the 2014 Hopman Cup Tomic lost to Milos Raonic (6–7, 1–6) but then he defeated Andreas Seppi (4–6, 6–3, 6–2) and Grzegorz Panfil (6–1, 6–4). Australia team finished in last place in the group. World Tennis Challenge (3–0) In 2010, Tomic won the World Tennis Challenge for the Australasia team. Tomic won all three singles matches, defeating Gilles Simon, Radek Štěpánek and Robby Ginepri. Fast 4 Tennis Showdown (1–0) On 9 January 2017, Bernard Tomic defeated Dominic Thiem 3–4 4–2 4–3 3–4 5–3 to win the event. Before this match, Nick Kyrgios defeated Rafael Nadal 4–3, 2–4, 4–3 4–3. With Australia leading 2–0, the doubles were not played. Coaching Tomic was first coached by Gold Coast tennis instructor Neil Guiney at age 7. As a child Tomic was officially coached by his father, John, at Queens Park Tennis Centre on the Gold Coast. Despite his father never having played tennis, he continues to coach Tomic. In November 2012 it was revealed that Tomic had approached Australian tennis legend Pat Cash to coach him on a full-time basis. Cash declined the offer. As of 2016, Tomic was training out of Koza World of sports tennis academy with Australian coach Gavin Hopper. Equipment and sponsors In March 2006, a 13-year-old Tomic signed a six-figure deal with sports marketing and management giant IMG. Prior to joining the ITF juniors tour

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.
