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>
Tony Hrkac Anthony John Hrkac (; born July 7, 1966) is a Canadian former professional ice hockey player of Croatian and Ukrainian ancestry who played eighteen seasons of professional hockey. Playing career College Hrkac was drafted in the second round, 32nd overall, by the St. Louis Blues in the 1984 NHL Entry Draft. Hrkac played collegiately at the University of North Dakota, and was the recipient of the Hobey Baker Award for top men's collegiate hockey player during the 1986–87 season. He led the team (along with future Chicago Blackhawks teammate and Hockey Hall of Fame inductee Ed Belfour) —widely known during this period as the "Hrkac Circus" (the name rhymes) — to a national championship and his 116 points that season still stands as the NCAA single-season scoring mark. National Hockey League He made his National Hockey League debut with the Blues during the 1987 NHL playoffs, appearing in three games. After two-plus seasons with the Blues, he was traded (along with Greg Millen) to the Quebec Nordiques in exchange for Jeff Brown. In his NHL career, Hrkac would play for the Blues, Nordiques, San Jose Sharks, Chicago Blackhawks, Dallas Stars, Edmonton Oilers, New York Islanders, Mighty Ducks of Anaheim, and Atlanta Thrashers. Hrkac's rights were also briefly owned by the Pittsburgh Penguins when they acquired him and Bobby Dollas from the Edmonton Oilers for forward Josef Beranek. On June 26, ten days after initially acquiring Hrkac, the Penguins lost Hrkac to the Nashville Predators in the 1998 NHL Expansion Draft. Less than two weeks later, Hrkac was moved; this time to the Dallas Stars. He was traded on July 9, 1998 for future considerations. In 758 career NHL games, Hrkac scored 132 goals and added 239 assists. He also appeared in 41 playoff games, scoring seven goals and adding seven assists. Four of those seven goals came in one game against the Chicago Blackhawks on April 10, 1988, setting a St. Louis Blues record for most goals scored in a playoff game by one player. Hrkac was a member of the 1998–99 Dallas Stars team which won the Stanley Cup. American Hockey League Hrkac returned to the minor leagues in 2003 after he was unable to sign with an NHL club. He was a key player on the Calder Cup champion Milwaukee Admirals in 2003–04. While there were rumors that the St. Louis Blues were seeking to sign him for one last stint with his original team, Hrkac retired after the 2004–05 season. Hrkac came out of retirement for the 2008–09 season, at the age of 42, by signing with the AHL's Houston Aeros on March 11, 2009. Awards and honours 1986-87, Hobey Baker Award, NCAA 1992-93, James Gatschene Memorial Trophy, awarded to the Most Valuable Player who showed sportsmanship, IHL 1992-93, Leo P.

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.
