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>
Reaction Hero Reaction Hero is a remix double-CD release, sourced from and reinterpreting original tracks on Little Nobody's preceding album Action Hero (2000). It features new mixes from Little Nobody, as well as from international producers Si Begg, Tal (Sub Rosa), Tobias Schmidt (Tresor), Vocoderman, Brixton, Magnet Toy, and Yamaoka . The Australian producers involved include Steve Law (Melbourne's Zen Paradox), Digital Primate, Pnau, Sameer Sengupta (Sydney producer Pocket), Schlock Tactile, the LN Elektronische Ensemble, Cinnaman from Adelaide's Dirty House, Isnod, Son Of Zev, Nicole Skeltys (Artificial), 5000 Fingers of Dr. T, Brewster B, Zog, Beam Up (Noodles Discotheque), DJ Tweaka, The Alcoiids, Kandyman, and vocalist Marcella Brassett. Critical reception "Take one Little Nobody, a notorious indie electronic label, and a whole lot of remixers and the result is a double-CD of the most eclectic remixes around," wrote Chloe Sasson in her review that appeared in Sydney's 3D World in 2001. "Little Nobody, aka Andrez Bergen, has been a man around town for years. Beginning his days as electronic music editor for industrial's Dark Angel, Andrez has paid his dues as remixer, editor, journo and all round nice guy. Being such a top cat, Andrez had the idea of inviting established local producers (Son of Zev, 5000 Fingers of Dr T and Nod), convincing overseas big guns (Tobias Schmidt, Si Begg) and extending the chance to a few talented no-names (The Alcoiids) to take their hand at reworking some of his original tracks. The result is a pleasing hodge-podge that travels the electronic train through the sounds of techno, drum and bass and way-out electronica. While the addictive Cocaine Speaking appears as complete remix or tasty sample in many of the 32 tracks featured, the individuality of each producer dominates, producing one of the most interesting and unique remix albums around." "Fans of a little leftfield electronic indulgence should look no further than this latest release from Melbourne's If? Records and label founder Little Nobody," wrote Dan Stinton, the former editor of Perth's Hype magazine, that same year. "Featuring 2 CDs and some 46 tracks, Reaction Hero follows on from Little Nobody's recent album Action Hero with remixes from some of the world's most respected electronic artists. The release spans twisted hip-hop rhythms, weird breaks and quirky techno featuring names such as Tobias Schmidt, Si Begg and Yamaoka as well as new material from Mr Nobody himself. This is certainly a diverse and difficult listen, but well worth checking out for its innovation and forward thinking sounds." Track listing "Buffed Up & Then Some" (Little Nobody) "Devolution Maybe?

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.
