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>
of a delay in the final paperwork for the revamped station. According to some reports, it may have still been using the WCHU call letters when it signed on at full power for the first time. The station moved from the Inman Hotel to its current studio facility on Country Fair Drive in 1978. In 1986, Plains Television sold WICS to Guy Gannett Broadcasting (no relation to the much larger Gannett Company), but retained WICD. The two stations operated as a regional network simulcasting most network and syndicated programming. This arrangement nearly brought down WICD, even though it was a very prosperous period for NBC as a whole. For much of the 1980s it looked like channel 15 would revert to being a full-time satellite of WICS. In 1994, Plains Television sold WICD to Guy Gannett, who pumped significant resources into the station, particularly its news department. Guy Gannett then sold most of its television properties, including WICD/WICS, to the Sinclair Broadcast Group in 1999. Soon after Sinclair took over, it turned around and announced it was selling WICS/WICD as well as KGAN in Cedar Rapids, Iowa to Sunrise Television. However, the FCC did not allow Sunrise to buy WICD/WICS due to Sunrise's ownership structure. Hicks, Muse, Tate & Furst (HMTF), an investment firm controlled by then-Texas Rangers and Dallas Stars owner Tom Hicks, owned a large block of Sunrise stock. HMTF is majority stockholder of the LIN TV Corporation, then-owner of WAND in Decatur. The FCC ruled HMTF held enough stock in Sunrise that an acquisition of WICD/WICS would result in a duopoly between two of the four highest-rated stations in the market, which is forbidden by FCC rules. Sinclair subsequently withdrew the offer to sell the three stations in 2000. The station's 46-year affiliation with NBC ended on September 5, 2005 when, as part of a larger national deal between LIN TV and NBC that also involved WDTN in Dayton, Ohio (who swapped affiliations with WICS/WICD's Dayton sister station WKEF the year before), WICD and WICS swapped affiliations with WAND and became ABC affiliates. With this switch, WICD replaced WAND as the default ABC affiliate for the Illinois side of the Terre Haute, Indiana market, which had not had an ABC affiliate of its own since longtime affiliate WBAK-TV switched to Fox in 1995. The network swap actually improved reception for ABC programming on the Illinois side of the market. WICD's transmitter is not far from the Indiana line, while WAND's transmitter in Argenta is near the middle of the state. Due to contracts with satellite providers, for a long time WICS was the only ABC station in the market uplinked on the Champaign/Urbana/Springfield local feeds. However, Dish Network's Champaign/Urbana/Springfield feed began airing WICD on February 23, 2013 alongside WICS. For the same reason, when Dish dropped WRTV from Indianapolis as the local ABC affiliate for the Terre Haute feed, it uplinked WICS rather than WICD. This ended at the start of the 2011–12 television season, when WAWV-TV rejoined ABC. In March 2011, WICD added music video channel TheCoolTV to its second digital subchannel and Comcast digital channel 807. On August 31, 2012, TheCoolTV was dropped from all Sinclair stations, including WICD. On December 31, 2012, Sinclair Broadcast Group closed on the purchase of the non-license assets of GOCOM's three television stations, WRSP/WCCU and sister station WBUI for approximately $25.6 million. Sinclair is providing sales and other non-programming services to the stations pursuant to shared services and joint sales agreements. Both WRSP/WCCU and WBUI were initially operated from separate facilities from WICS/WICD. However, WCCU quickly moved its advertising

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.
