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>
players and children in the match entrance. The stadium mascot was reintroduced with a new costume in 2005, named Galo Doido ("Crazy Rooster") by the supporters. Kits The club's home kit has always consisted of a black-and-white vertically striped shirt, with black shorts and white or black socks. The width of the black and white stripes has varied from season to season, as has the colour of the shirt numbers, which have usually been red, black, white or yellow. Atlético's traditional away kit is all-white shirts, shorts and socks, but has had slight variations. An all-black third kit was introduced in the 2000 season, being used again in 2015. In 2008, a black-and-gold vertically striped third kit was launched to commemorate the club's centenary, featuring the first crest. Squad number 12 is retired from the club's kits, dedicated to the fans. Since the 1981 season, the club has had its kits manufactured by sportswear corporations, the first one being Brazilian company Rainha. Since 2017, Atlético's kits are manufactured by Topper, a company which previously provided apparel for the club from 2010 to 2012. Other previous suppliers were Adidas (1983–85), Penalty (1986–90, 1992–93 and 1997–2001), Dell'erba (1991), Umbro (1994–96 and 2002–04), Diadora (2005–07), Lotto (2008–09), Lupo (2013), Puma (2014–2015) and Dryworld (2016). In 1982, bank Credireal was Atlético's first shirt sponsor. After one sponsorless season in 1983, Precon, a construction company, appeared on the shirts in 1984 and 1985; it was replaced by Agrimisa bank in 1986. In 1987, Coca-Cola sponsored all participating clubs of Copa União, and the brand remained on Atlético's kits until 1994. The club was subsequently sponsored by TAM Airlines (1995–96), Tenda (1997–98), and had temporary deals with Fiat and Telemar in 1999. Two sponsorless years followed, before permanent deals were signed with Fiat (2002–03), MRV Engenharia (2004–07) and Fiat again in 2008. After one more season without a brand on the club's shirts, BMG, a bank that was owned by the former club president Ricardo Annes Guimarães, was the main sponsor from 2010 to 2014. MRV returned as the club's main shirt sponsor in 2015, being replaced by state-owned bank Caixa Econômica Federal in 2016. Grounds Atlético had its first home ground built in 1912 at Paraopeba Avenue, in downtown Belo Horizonte, across the street from América's first stadium. The club's main ground for most of its early years, however, was the Presidente Antônio Carlos stadium, which held 5,000 people; it was nicknamed Estádio de Lourdes for the quarter in which it was located. The Antônio Carlos was one of the first stadiums in Brazil to feature floodlights, and opened on 30 May 1929 with a friendly against Corinthians, won by Atlético 4–2. The following year, the stadium was visited by FIFA president Jules Rimet, who watched a night game for the first time. The stadium fell out of favour when the larger Independência was built in 1950, and remained largely unused by the first team; eventually it was sold by the club to the Belo Horizonte municipality in the 1960s. After decades of legal disputes with the municipal government, the property returned to the club in 1991. It was leased to a shopping mall in 1995, which was built in the following year where the stadium once was, across the street from Atlético's administrative headquarters. Construction for the Independência (officially Estádio Raimundo Sampaio) started in 1947 in preparation for the 1950 FIFA World Cup, during which its first match was played. Originally the property of the State Government of Minas Gerais, ownership was transferred to Sete de Setembro FC in 1965, when the Mineirão was

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.
