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>
¡Mayday! ¡Mayday! is an American hip hop group from Miami, Florida. The group consists of rappers (Bernz) Bernardo Garcia and Ben Miller (a.k.a. Wrekonize) along with producer, and percussionist Andrews Mujica (a.k.a. NonMS); keyboard player and guitarist Aaron Eckhart (a.k.a. Plex Luthor), drummer Terrel (a.k.a. L T Hopkins), and bassist Gianni Perocapi (a.k.a. Gianni Ca$h) were part of the group until 2015. The band is currently signed to Tech N9ne's Strange Music label. Career Foundation and Early Days (2003-2009) The group was founded by Plex Luthor and Bernz in Miami, 2003. The band is known for its Miami-underground hit "Quicksand", which earned them a deal with SouthBeat Records, and their first single and 2006 music video "Groundhog Day", featuring Cee-Lo Green (directed by Jokes) which received over 2 million views on the online video site YouTube within only a day of being added. The band released their first studio album, ¡Mayday!, in September 2006. In 2008, producer Gianni Ca$h joined the group. In 2009, vocalist and producer Wrekonize, percussionist NonMS, and drummer L.T. Hopkins joined ¡Mayday!, bringing the number of members to 6. In February 2009, ¡Mayday! released their first EP "The Thinnest Line". A few months later, in June 2009, they released a follow-up EP titled "Technology". Lords of the Fly & Stuck on an Island (2010) Lil Wayne worked with the group for two unofficial videos; both videos - "Da Da Da" and "Get a Life", were filmed on the roof of a building in the middle of the day, with spectators apparently attending a free concert. Shortly after working with Lil Wayne, remixes of both tracks, plus another Lil Wayne track "On Fire" were released on ¡Mayday!'s first mixtape "Lords of the Fly". The mixtape included new tracks, remixes, and freestyles to serve as a prelude to their next album Stuck on an Island, which released shortly after. Signing with Strange Music (2011 - Present) In early 2011 independent label frontman Tech N9ne reached out to ¡Mayday!, and featured them on two tracks of his album Welcome to Strangeland. Bernz and Wrekonize were also featured on a bonus track of the album. On June 3, 2011, Mayday signed with Strange Music. Their third studio album, Take Me to Your Leader was their first major album released under Strange Music on March 26, 2012. The lead single from that album titled "Badlands" and featuring Tech N9ne received over half a million views on YouTube within the first two months. On August 27, 2012, Miami New Times uploaded a list of the 50 Best Miami Bands of All Time where ¡Mayday! was listed as #27. Along with their placement on the list, Miami New Times stated that "¡Mayday! just might be Miami rap's future." On August 7, 2012, ¡Mayday! released their first EP under Strange Music, "Thrift Store Halos". On July 16, 2013, Mayday released their fourth studio album Believers. They also featured on Tech N9ne's single "Fragile", along with Kendrick Lamar, which was released shortly after Believers. In 2013, the band went on tour with Tech N9ne during his Something Else Tour. In 2014 on June 10, Members of ¡Mayday! teamed up with newly signed Strange Music artist Murs to bring together ¡Mursday!. Shortly after the release of ¡Mursday!, ¡Mayday! and Murs released a free EP on Soundcloud presented by Boost Mobile titled "Ready 2 Run". Shortly before ¡Mayday! released their sixth studio album Future Vintage on September 18, 2015, Plex Luthor formally departed the group on good terms. After the album release, the group toured all around the country. Along with touring, rappers Bernz and Wrekonize have

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.
