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>
Jorden van Foreest Jhr. Jorden van Foreest (born 30 April 1999) is a Dutch chess grandmaster. He was Dutch Chess Champion in 2016. Chess career Introduced to the game by his father, Van Foreest learned to play chess at the age of six but did not play regularly until he was nine. 2013–2016 In 2013, Van Foreest won the European U14 Chess Championship with a score of 7½/9 (+6–0=3). He earned his international master title in 2014 at the age of 15 and secured all the norms needed for the grandmaster title in 2015 at the age of 16. He was officially awarded his grandmaster title by FIDE in 2016. This makes him the Netherlands' youngest ever grandmaster (Anish Giri was awarded the title at a younger age but was not a Dutch player at the time). In September 2015, he competed in the World Junior Chess Championship. He finished sixth, scoring 8/13 (+5–2=6).

From 28 October to 6 November, he competed for the Netherlands on board 4 at the 2017 European Team Chess Championship. He scored 5/7 (+4–1=2) for a performance rating of 2723. From 13 to 25 November, he competed at the World Junior Chess Championship. He placed fifth with a score of 8/11 (+7–2=2), half a point behind the winner Aryan Tari. From 13 to 28 January 2018, Van Foreest competed in the Tata Steel Challengers. He finished fifth, scoring 7½/13 (+4–2=7). He competed in the 81st Tata Steel Masters in January 2019, placing thirteenth with 4½/13 (+3–7=3). In July, Van Foreest shared first in the 2019 Dutch Championship with 5/7 (+3–0=4), losing on tiebreak to his younger brother Lucas van Foreest. At the 82nd Tata Steel Masters in January 2020, Van Foreest placed fourth with 7/13 (+3–2=8). Personal life Born in Utrecht on 30 April 1999 and raised in Groningen, Van Foreest comes from the noble Van Foreest family and has the honorific of jonkheer. He is the great-great grandson of Arnold van Foreest and great-great grandnephew of Dirk van Foreest. Both Arnold and Dirk were three-time Dutch Chess Champions (Arnold: 1889, 1893, 1902; Dirk: 1885, 1886, 1887). Jorden is the eldest child of his family and has five siblings: four brothers and one sister. His father Nicky van Foreest works the Faculty of Economics and Business of the University of Groningen, and his mother Shiela Timp is a medical doctor and computer programmer. His younger brother, Lucas (born 2001), earned the title of grandmaster in 2018.

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.
