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>
I Am a Bird Now I Am a Bird Now is the second album by New York City band Antony and the Johnsons. It won the Mercury Prize on September 6, 2005. After winning the prize, the album shot up the UK albums chart from #135 to #16 in one week, the biggest jump in the history of the Mercury Music Prize. As of September 2011, UK sales stood at 220,000 copies. The album features guest appearances by Rufus Wainwright ("What Can I Do?"), Devendra Banhart, Joan Wasser and by lead singer Anohni's childhood heroes Boy George and Lou Reed. The cover is a photograph by Peter Hujar of Warhol Superstar Candy Darling on her deathbed (aptly titled "Candy Darling on Her Deathbed"). Reception I Am a Bird Now received very positive reviews. On the review aggregate site Metacritic, the album has a score of 88 out of 100, indicating "universal acclaim." Drowned in Sounds Anthony Gibbons gave the album a score of 10/10, writing "It's not an exaggeration. This isn't hype. I Am A Bird Now is a beautiful, emotive, glorious, and sometimes sinister album that will top many a critic's list come the end-of-year polls, and justifiably so." Tiny Mix Tapes also gave the album a perfect score, writing "This music grabs a hold of you and doesn't let go. It feels timeless and gorgeous and bigger than life. It may not be 'soul' in the strict, music appreciation 101 sense, but it could make even the most jaded atheist approach a metaphysical regard... I'd put on my critic's cap and dive into scrutiny, but I am too enraptured by this artist's music." Pitchforks Brandon Stosuy praised the vocals, writing "The ultimate draw is Antony's voice, and within the first two seconds of the album, it should be very clear to even the most unaware newbies that Antony has an amazing Nina Simone/Brian Ferry [sic]/Jimmy Scott vibrato, a multi-octave siren that would sound painfully lovely no matter what he was saying." The album has appeared on several end of year lists. Mojo named I Am a Bird Now the best album of 2005. Pitchfork ranked the album #5 on its list of the top 50 albums of 2005. On the same website, the track "Hope There's Someone" was ranked #28 on their list of the Top 500 Songs of the 2000s and was selected as 2005's best single. In 2019, the album was ranked 40th on The Guardian'''s 100 Best Albums of the 21st Century list.

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.

  c. Make sure there are no missing or misplaced tags.
 
Remember to analyze the entire passage, identify all relevant PI-KFI pairs, and provide the output for each pair as specified. After completing the analysis, present the original passage with the <|retrieval|> tokens inserted in their appropriate positions as part of a new key in the JSON file. Only Ouput the JSON File.
