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>
WTHK WTHK (100.7 FM; "The Peak") is a radio station broadcasting a classic rock format. It is licensed to Wilmington, Vermont. The station is currently owned by Jeffrey Shapiro's Great Eastern Radio, and currently simulcasts sister station WKKN (101.9 FM). History WTHK began its radio life as WVAY. The station was part of the 'wave' of upscale smooth jazz formatted stations that were very trendy in the mid to late 1980s. The station was owned and operated by Rothschild Broadcasting. Founding Program Director Roger Coryell left the station in 1990 for a position as morning host on San Francisco "Smooth Jazz" outlet KKSF. WVAY's slogan evolved from "Smooth Sounds - 100.7 WVAY" to 100.7 WVAY, Different by Design as the station evolved into more of a triple-A formatted radio station. At one time WVAY also had additional translators at 99.7 in Marlboro, Vermont, which was sold to Harvest Broadcasting, a religious broadcaster, and had an arrangement to operate a translator at 100.1 which helped WVAY have a stronger signal in Manchester, Vermont. At one time WVAY was positioned as 100.7/100.1 WVAY Different By Design. The station was sold to Dynacom Corporation in 1998, and wound up having many simulcast partners of the Dynacom stable which included being part of the soft AC, "Wish" stations (now WXLF), and AOR formatted Q 106 (WHDQ) from Claremont, New Hampshire. Eventually the simulcast partner became WRSI (then at 95.3 FM), an AAA station from Greenfield, Massachusetts. The WVAY call letters were shelved in favor of WMTT during this time. In October 2000, the WRSI simulcast with WMTT ended and was moved to WRSY (101.5 FM) in Marlboro, Vermont which had a better signal into Brattleboro, yet continued to serve the Deerfield Valley. WMTT's new simulcast partner became WEXP (101.5 FM) from Brandon, Vermont and together the stations were known on air as Classic Rock 101, The Fox. It was at that time that the WVAY call sign were restored to 100.7. In 2004 Nassau Broadcasting Partners purchased WEXP and WVAY as well as an entire portfolio of radio stations in Vermont and New Hampshire from the Vox Radio Group. While the station has evolved into "Rutland's Rock Station, 101.5 The Fox", the WVAY call sign went away again in favor of Nassau's warehousing of the WTHK call sign in 2006, where they remain to this day. The call sign was previously used on an 97.5 FM station in Trenton, New Jersey. WTHK, along with 29 other Nassau stations in northern New England, was purchased at bankruptcy auction by Carlisle Capital Corporation, a company controlled by Bill Binnie (owner of WBIN-TV in Derry), on May 22, 2012. The station, and 12 of the other stations, would then be acquired by Vertical Capital Partners, controlled by Jeff Shapiro; however, WTHK was not included in the subsequent sale of simulcast partner WEXP to Electromagnetic Company. The sale of WTHK and the other 12 stations was consummated on November 30, 2012, at a purchase price of $4.4 million. The Vertical Capital Partners stations were transferred to Shapiro's existing Great Eastern Radio group on January 1, 2013. On January 22, 2013, WTHK dropped its simulcast of WEXP and began simulcasting new sister station WXXK (100.5 FM). The WXXK simulcast ended on March 16, 2015, when WTHK, along with WKKN in Westminster (a station in the Keene, New Hampshire area that had also been serving as a WXXK simulcast), launched an adult album alternative format branded as "The Peak." Under the new format, the WTHK signal is marketed to the Bennington area. The stations switched to a classic rock format

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.
