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>
texts for the piece, which is based on a collection of Irish prayers and poems. It was performed for the first time in Dublin in November 2008. Ó Lionáird collaborated with Donnacha Dennehy during Dennehy's research for and composition of Grá agus Bás, a work that "incorporates traditional sean nos singing within a contemporary music idiom". Commissioned by Trinity College, Dublin, the work was first performed in Dublin in February 2007 by Ó Lionáird and the Crash Ensemble with Alan Pierson conducting. It had its United States premiere at the Merkin Concert Hall in New York City in March 2007, in what the New York Times called a "powerful account" of a "magnificently energetic, wildly cacophonous vocal work". Ó Lionáird sang the piece at Carnegie Hall in May 2013 in a concert of Dennehy's music with the Crash Ensemble and Dawn Upshaw. Nonesuch Records released a CD recording entitled Grá Agus Bás containing this and other works by Dennehy in May 2011. Along with fiddlers Martin Hayes and Caoimhín Ó Raghallaigh, guitarist Dennis Cahill, and pianist Doveman, Ó Lionáird is a member of The Gloaming, an Irish-American supergroup whose self-titled first album was released in 2014, winning the Meteor Choice Music Prize for Irish album of the year. From September 2016 Ó Lionáird appeared in The Hunger, an opera by Donnacha Dennehy about the Great Famine. Other work In 2013 University College Cork appointed Ó Lionáird the School of Music and Theatre's first Traditional Artist in Residence. In that capacity he gave lectures and taught sean-nós singing, as well as performing. Ó Lionáird appears in the 2015 film Brooklyn. He has said that he was reluctant to take the role "because I'm not an actor" but that he decided to accept when he learned that Colm Tóibín, the author of the novel on which the film was based, had asked the film's director to ask him. Ó Lionáird plays Frankie Doran, a poor workingman who sings the traditional song "Casadh an tSúgáin" (Twisting the Rope) during Christmas dinner at a soup kitchen. In May 2015 Ó Lionáird hosted a five-part radio documentary series about singing entitled Vocal Chords, which drew on "personal experience, academic contributions and a global cast of vocalists" including Sinéad O'Connor and Christy Moore. Personal life Ó Lionáird earned a Master of Arts degree in ethnomusicology from the University of Limerick in 2003. He lives in Inistioge in County Kilkenny with his wife Eimear and their three children.

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.
