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>
Sándor Kocsis Sándor Péter Kocsis (; 21 September 1929 – 22 July 1979) was a Hungarian footballer who played for Ferencváros TC, Budapest Honvéd, Young Fellows Zürich, FC Barcelona and Hungary as a striker. During the 1950s, along with Ferenc Puskás, Zoltán Czibor, József Bozsik and Nándor Hidegkuti, he was a member of the Mighty Magyars. After the 1956 Hungarian Revolution, he moved to Spain where he became a member of the FC Barcelona team of the late 1950s. Kocsis was a prolific goalscorer for both Budapest Honvéd and Hungary. While playing for Honvéd, he was the top goal scorer in any European league in both 1952 and 1954. He also scored 75 goals in 68 appearances for Hungary – a 1.10 goal/game average at the game's highest level. Kocsis was the top goal scorer in the 1954 World Cup with 11 goals, being the first player to score two hat tricks in a World Cup. His 2.2 goal/game average in the World Cup finals is second only to that of Ernst Wilimowski who scored four goals in his only World Cup match, and only Just Fontaine has scored more goals than Kocsis in a single World Cup. Kocsis was particularly known for scoring headers. His 1.103 goals/game average is ranked No.1 for players past 43 caps in FIFA class-A competition, closely followed by Gerd Müller with 1.097 goals/game (68 scores in 62 games), and are the only two players in history above a +1.0 goals/game average encompassing more than 43 internationals. Ferenc Puskás with .99 goals/game (84 goals in 85 matches) is currently ranked 3rd. Sándor Kocsis registered seven hat tricks for Hungary. Career Early years Kocsis was born in Budapest. He began his career as a junior with Kőbányai TC, before joining Ferencváros TC in 1946. There, he won his first Hungarian League title in 1949. He was then conscripted into the army and joined the army club, Honvéd. His team mates at Honvéd included Ferenc Puskás, Zoltán Czibor and József Bozsik. During his time at the club he won three more Hungarian League titles in 1952, 1954 and 1955. He finished as top goalscorer in the league on three occasions in 1951, 1952 and 1954 scoring 30, 36 and 33 goals respectively. On the latter two occasions he was also the top goalscorer in any European league. During the 1952 season at Honvéd, Kocsis was the world's top goalscorer in world 1st division football with 36 goals. He repeated that feat in 1954 with 33 goals. Kocsis made his debut for the senior Hungary team in 1948. Together with Ferenc Puskás, Zoltán Czibor, József Bozsik and Nándor Hidegkuti, he formed the offensive nucleus of the Golden Team that went unbeaten for 32 consecutive games. The Hungarian national team suffered no defeats in Class-A international matches between 4 June 1950 and 4 July 1954, in the 1954 FIFA World Cup Final. Kocsis scored his first international hat trick in a game against Sweden on 20 November 1949, and he scored a further one on 22 June 1952 against Finland. Kocsis also scored six goals at the Olympics in Helsinki as Hungary became Olympic Champions in 1952. On 19 October 1952, he scored his third international hat trick in a game against Czechoslovakia. In 1953, Hungary defeated England 6–3 at Wembley Stadium and then in 1954 by 7–1 in Budapest. During the latter game, Kocsis added a further two goals.

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.
