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>
WMXZ WMXZ (95.9 FM, "Mix 95.9") is a radio station licensed to Isle of Palms, South Carolina, United States, serving the South Carolina Lowcountry. The station is owned by Saga Communications, Inc. WMXZ airs a Top 40/CHR format. The station's studios are located in Charleston (east of the Cooper River) and the transmitter tower is in West Ashley, South Carolina. In 2012, WMXZ commenced HD Radio service with 99.3 The Box on the HD2 channel, featuring Urban and R&B music. History Vic Whetstone owned WWBD in Bamberg, South Carolina for 25 years. Miller Communications, a company based in Sumter, South Carolina, acquired it in 2003. It then became a classic rock station as "Bad Dog 95.7". In September 2005, WWBD upgraded from 6,000 to 25,000 watts with a new 500-foot tower in Canaan. In 2006, WWBD changed to country music as "Outlaw 95.7" but listeners overwhelmingly demanded that Bad Dog return, so it did after four months. In June 2007, Miller applied for a change in the city of license to Isle of Palms near Charleston but said Bad Dog would stay in Orangeburg. Apex Broadcasting, owner of WXTC, WIHB, and WXST, purchased WWBD from Miller in a deal announced in July 2008. The power had been increased to 50,000 watts. WSPO was part of a large frequency swap in Charleston and Myrtle Beach. The 96.1 frequency in Charleston moved to the Myrtle Beach market and became the new home of WKZQ-FM. WKZQ's former 101.7 frequency moved to Hanahan and is owned by Apex Broadcasting. This allowed the Charleston metro area to get a new station, as WWBD moved to Isle of Palms with Apex as its new owner. The Bad Dog format began simulcasting with Miller's 105.1 WGFG on January 14, 2009. The simulcast stopped and 95.7 FM is now silent, with WQKI-FM expected to take over the frequency. The station was assigned the WSPO call letters by the Federal Communications Commission on February 25, 2009. They were switched to WIOP in June 2009 when the WSPO calls went to the sister station at 1390 AM with its new sports talk format. On June 18, 2009, FM 95.9 launched in the Charleston area with a classic hits format, last heard on WXLY before it dropped the format in favor of adult contemporary in late 2007. The station re-imaged as "95-9 IOP" in August 2010, and switched to country music on September 15, 2010 as "Kickin 95.9, Real Country Variety". On May 31, 2011, WIHB (now WCKN) began simulcasting WIOP. On June 13, 2011 WIOP stopped simulcasting and began stunting with construction sounds. On June 15, 2011 WIOP ended stunting and changed their format to soft adult contemporary, branded as "Lite 95.9". The station featured a blend of light AC hits, softer rock oldies, and some adult standards from the 1960s through the early 2000s but was entirely gold-based, playing no current product. Artists heard on Lite 95.9 included Lionel Richie, Elton John, Billy Joel, Carly Simon, Mariah Carey, Olivia Newton-John, Josh Groban, Eric Clapton, Celine Dion, Kenny Rogers, and Barbra Streisand. On March 5, 2012, WIOP became the "New Mix 95.9", with hot adult contemporary, and changed their call letters to WMXZ on March 14, 2012. In 2014, "Mix 95.9" became "Mix 96" and while still CHR the station is trying to compete with Charleston's Cumulus-owned WSSX "95-SX.", the only other CHR in the market. That all changed in April 2017, when Mediabase moved the station to the Top 40/CHR panel. In July 2017, WMXZ reverted to the "Mix 95.9" branding. On September 6, 2017, the sale of the

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.
