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>
Bom-Bane created 5 Down 20 Across, which turned the building itself into a puzzle. Audience members were invited to solve this by collecting clues from all the doors in the building. Each door had a black-and-white painting by a different artist. Merrily on High In 2013, Jane Bom-Bane wrote a Christmas musical, Merrily on High, which was performed throughout December. This featured puppetry by Daisy Jordan (Barely Human Puppets), with singing by the madrigal folk trio The Silver Swans, comprising Bom-Bane, Emma Kilbey and Eliza Skelton, who is also the café's chef. The Long Lost River Song Bom-Bane's 2014 May fringe show was inspired by Brighton's lost secret river, an intermittent stream called the Wellesbourne. Five audience members were invited to follow the river, as it flowed from its source in the attic to 'a sea-bound chorus in the cellar, followed by a feast of foods foraged en route.' Rachel Blackman described the show in Fringe Review: 'We are invited into her bedroom for one act and her bathroom for another. We trace the river through rooms in the house, all the way down to the restaurant level, gathering cast members as the river itself gathers momentum. Finally we land in the restaurant area where we are fed a three course meal of simple, delicious fare sourced locally.' For this show, the company comprised Jane Bom-Bane, Eliza Skelton, Foz Foster, Colin Uttley, Freya Bowyes, Martin Peters, Lynne Thomas, Sarah Angliss and Daisy Jordan. Saippuakivikauppias Bom-Bane's 2015 fringe show was called Saippuakivikauppias, which means 'The Soapstone Seller' in Finnish, and is also thought to the longest palindromic word. This was a second collaboration between Jane Bom-Bane and the puppeteer Daisy Jordan. The show dramatised a tale originally written, in verse, by Bom-Bane in 2002, the year of the Palindrome. The audience followed the Midgard Serpent down into the underbelly of the cafe, where 'the tale of a troubled craftsman driven and hampered by his compulsion to remain symmetrical was told through song, puppetry and animation.' The songs were sung by Bom-Bane, Martin Peters and Eliza Skelton. The performance was followed by a Finnish meal, created by André and Anna Schmidt, including mackerel pâté, Firewater (vodka and cranberry juice), meatballs (veggie meatball option included) and Mustikkapiirakka (blueberry pie).'An all-round sensory treat, this thoughtful existential fable effortlessly sucks the audience into its beautifully rendered world,' said Nick Aldwinckle in The Argus. Bom-Banimals Bom-Banimals, in May 2016, was an animal themed fantasia, again taking place throughout the building. An audience of six was invited to move from room to room, encountering a series of musical animals (Eliza Skelton, Foz Foster, Kate Daisy Grant, Raven Kaliana, Jo McDonagh, Sebas Contreras, Kate Vaughan, and Tom Walker). Rachel Blackman described the experience in Fringe Review: 'We barely manage to squeeze into each of the modest spaces with the performers who gradually accumulate and eventually outnumber us. In each room we meet a different animal, all of whom must sacrifice a beloved item in order to find their authentic voice....if there is a message to be had, it is a light one, but touches on the notion that if we love someone, giving a piece of ourselves is a risk, but can pay off one hundredfold....And a plea maybe for the ongoing existence of this kind of intimate, real time, unrepeatable experience, where the value to each of us is so much more rich, raw and indescribable than the price of a ticket.' The show was also reviewed in Total Theatre and received five stars from the Argus. Snow White and the Seven Sisters For Christmas 2018, Jane

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.
