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>
WDAO WDAO "The Real Rhythm Of The City" is a daytime-only commercial AM radio station in Dayton, Ohio operating on the frequency of 1210 kHz with a power of 1,000 watts. Its studios are currently located on West Third Street with transmitter located in South Dayton. The WDAO calls came as a result of all stations East of the Mississippi which begins with "W", the "DA" is for Dayton and the "O" is for Ohio. FM history WDAO started in the fall of 1964 at 107.7 MHz on FM (currently home to WMMX "Mix 107.7") Not only was it the first R&B-formatted station in the Miami Valley, it was also the first FM station of its kind in America; it was the sister to AM daytimer WAVI, owned and operated by H.K. "Bud" Crowl its founder, (dba:WAVI Broadcasting Corp.) when its original studios were located adjacent to Interstate 75 at 1400 Cincinnati Street. Billed as "the soul of Dayton" it broadcast the hits of the Memphis and Motown soul era of the 1960s and into the Philadelphia disco sound of the 1970s. Like its Top 40 AM competitor WING, it also had a stable of on-air personalities including Kenny Ray Tevis, George Truehart, "Big Ray" Meaders, Bill "Biggie B.C." Carr, Robert "Bob" Patton, "Shotgun" Pleasant, Long John Silver, Lankford "The Man" Stevens, Mack J. Pettigrew, Jim Johnson, Dr. John "Turk" Logan, Michael Ecton, Brinda "Let's Rock" Carter, a graduate of the (dba: IBC)International College of Broadcasting of Dayton, Ohio and the late Rick Smith (later of WHIO-TV). WING alumnus Gene "By Golly" Barry also worked at WDAO as program director in the late 1970s in addition to hosting a weekend oldies program on WAVI in the early 1980s. WDAO-FM was the most popular of Crowl's stations, the other being "people power" WAVI with a talk format sometimes mixed with adult standards and a simulcast of WDAO-FM's Sunday evening jazz program. Sunday morning Gospel was hosted by Stanley Henry of Springfield and Sunday evening had a program called "Backpage", hosted by Raymond Graham and Ro-Nita Hawes (the latter would later go on to launch WROU in 1991, and would own that station until she sold it to Radio One in 2004). AM history Bud Crowl sold both WDAO-FM and WAVI to Stoner Broadcasting shortly before his death in 1985. Stoner chose to move WDAO to the former WAVI AM frequency and rebranding the FM as adult contemporary WWSN "Star 107.7" (now iHeart Media-owned WMMX "Mix 107.7.") where both remain to this day. WDAO's morning soul gospel DJ and WDAO's top salesperson, Jim Johnson became station manager of WDAO while Alan Gray became General Manager for both stations. Johnson eventually purchased WDAO from Stoner when they were no longer interested in the station. Stoner merged with Jacor in the 1990s and later with Clear Channel Communications in 1998. Clear Channel is now known as iHeart Media. In 1955, Crowl purchased the former WWSO (then licensed to and located in Springfield) after it went off the air a year earlier and successfully moved its city of license and entire operation to Dayton and given the WAVI calls that same year. (WAVI was short for "Aviation" to become synonymous with Dayton being known as the "Birthplace of Aviation" and that of Wilbur and Orville Wright.) The move to Dayton was practically coincidental with the move of AM daytimer WJEL from Dayton to Springfield where it became known as WBLY from 1954 to 2002. That station is now known as WULM. WAVI aired mostly adult standards in the 1950s and 60s before switching to 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.
