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>
2014, Hamasaki announced through her official Facebook page that she had started recording new material composed by Tetsuya Komuro, Kunio Tago and Tetsuya Yukumi for a "winter ballad trilogy" single. On November 6, 2014, the title of the single was revealed to be "Zutto.../Last Minute/Walk", and its release date was set for December 24, 2014. On November 10, 2014, it was announced that Hamasaki would be collaborating in a tribute cover album for Hikaru Utada, entitled Utada Hikaru no Uta, to be released on December 9, 2014. For the album she contributed with a cover of Utada's 1998 single "Movin' on Without You", which was arranged by the RedOne production team. The winter ballad trilogy single, "Zutto.../Last Minute/Walk", was released on December 24, 2014, and peaked at number five on the Oricon charts. With this achievement, Hamasaki became the first solo artist in Japan's history to have 50 singles within the Top 10 of the Oricon charts. As for artists in general, Hamasaki became the third artist with more Top ten singles since Oricon's foundation in 1968—being surpassed by groups Morning Musume and SMAP, with 57 and 53 Top ten singles respectively In December 2014 Hamasaki announced that she would be not attending the New Year show Kōhaku Uta Gassen for the first time in 15 years. She explained her decision stating that she wanted to lower her responsibilities and things she felt pressured to do, in order to focus on the projects she had for her career, mainly regarding her plans to expand her influence throughout Asia. On February 15, 2015, Hamasaki made a surprise guest appearance during Singaporean singer JJ Lin's concert in Taipei, Taiwan. They performed a duet version of Hamasaki's 2000 single "Seasons", and announced that JJ Lin would be producing a song for Hamasaki's next studio album, A One. The album was released on April 8, 2015, including singles "Zutto...", "Last Minute", "Walk", Utada's cover "Movin' on Without You", and JJ Lin-produced song "The Gift", for which a promotional music video was also made. Between April and July 2015, Hamasaki embarked on her Arena Tour 2015 A Cirque de Minuit tour throughout Japan, which was planned as an expanded version of her previous Countdown Live concerts held in late 2014. The tour consisted of a 34-song setlist show with a duration of 3 hours and 45 minutes, her longest concert held to date. At the final show of the aforementioned tour, Hamasaki announced that she would start another tour in September, this time exclusively for members of her official fan club, TeamAyu.

She also recorded a cover

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.
