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>
The Crüxshadows The Crüxshadows is an American dark wave and dark synthpop band currently based in Jacksonville, Florida, United States. The band has an international following of fans and has toured North America, Europe, and Asia. History The band was originally formed in 1992 by Rogue, Sean Flanagan and Tim Curry, in Tallahassee, Florida. 1990s 1992 - The Crüxshadows formed in Tallahassee, Florida by Rogue (vocals, words, concepts, drum-machines, songsmithing, & electric violins), Sean Flanagan (computers, drum machines, programming, and synthesis), and Tim Curry (computers, programming, equipment, & guitar work) during the summer. 1993 - The Crüxshadows self-released their debut album, ...night crawls in initially only as a cassette. 1994 - The Crüxshadows recorded and released ″Ballrooms on Mars″ on OLD SCHOOL RECORDS and re-recorded "Bloodline" from their '93 release. 1995 - The band recorded their second album Telemetry of a Fallen Angel. Initially it was simply a self released CD, but it was acquired and released by Nesak International/Kato Records, and later released & distributed by Dancing Ferret Discs. Years later it would be acquired by Rogue's own label Wishfire Records. 1996- Telemetry of a Fallen Angel was released nationally in the United States. 1997 - Both Sean Flanagan and Tim Curry left the band shortly after signing a record deal with Nesak International/KATO Records. Rogue absorbed their interest in the band as well as their commitments under the new contract, and became the only member of Crüxshadows for a time. Determined to not be dragged down by the comings and goings of other members, Rogue learned to use synthesizers & computers himself in order to maintain Cruxshadows' musical direction. 1998 - Rogue started working on new material for the band's follow-up album. He recruited several new players including Chris Brantley, Kevin Page, Rachel McDonnell, and Trevor Brown. The band resumed touring nationally and finished work on their third studio album. During this period The Cruxshadows signed an ill-fated deal with New England-based Mere Mortal Records to release The Mystery of the Whisper. A few months prior to putting out the disc, Mere Mortal was forced out of business due in part to its acquisition of a debt-heavy distributor. With a new album, but no label, The Cruxshadows eventually partnered with Patrick Rodgers' startup label Dancing Ferret Discs. The Cruxshadows would spend a little more than a decade signed to Dancing Ferret. 1999 - With their new label and a new lineup, the band released The Mystery of the Whisper, Until the Voices Fade..., and Paradox Addendum. By this time "Marilyn My Bitterness" and "Monsters" had become staples on the dance floors of a re-invigorated American Gothic-Industrial club scene. Capitalizing on the success of these songs, the band toured the United States relentlessly over the years that followed. The band's song "Eurydice" occupied the top position in the category of New Wave for several months on the charts of digital music pioneer MP3.com. 2000s 2000 - The band contributed a song titled "Deception" to Music from the Succubus Club, a disc sponsored by and based upon the popular whitewolf Vampire The Masquerade franchise. This song was also released in a German language version titled "Täuschung". Although "Deception" never charted, it became one of the band's most popular and enduring tracks. 2001 - They played their first tour of Europe and released a tour CD for their European live shows called Intercontinental Drift, later released as Echoes and Artifacts. 2002 - The EP Tears debuted at No 5 in the Deutsche Alternative Charts. The full length album Wishfire also placed at No. 2 on the DAC. The Crüxshadows toured both

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.
