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>
Maggie Rita's Maggie Rita's Tex-Mex Grill & Bar is a Tex-Mex restaurant in Houston. For several years, Maggie Rita's was a restaurant chain with a license co-owned by Carlos Mencia and Santiago Moreno of Suave Restaurant. In January 2013, Moreno closed the last two locations they owned. Tony Shannard owns the only remaining Maggie Rita's restaurant, which is situated in Houston's JPMorgan Chase Tower. History Carlos Mencia had an interest in food, and his friends suggested that he make a business out of it. Mencia met Santiago Moreno, a restaurateur, who suggested that the two of them start a restaurant chain. Mencia partnered with Moreno, who along with David Quintanilla, was one of the two principals of the Restaurant Resource Management Group, to open Maggie Rita's. The first Maggie Rita's opened was located in the Galleria area of Houston. T.J. Aulds of the Galveston County Daily News characterized the opening as a "test run" and Mencia said that "We learned a lot from that experience. We tweaked a lot of things from what we learned there." Shortly after Hurricane Katrina hit New Orleans, Maggie Rita's opened in that city. Around 2007 a former Houlihan's location in Houston was replaced with Maggie Rita's. Allison Wollam of the Houston Business Journal called the restaurant "a new upscale Mexican food concept." In 2009 Syd Kearney of 29-95 said that Maggie Rita's was an "upscale Tex-Mex sports bar." The Maggie Rita's in Galveston, Texas opened on July 29, 2010 in the Armour & Co. building in The Strand district. The Galveston location was the number three Maggie Rita's. Maggie Rita's had replaced a Fuddrucker's location. Laura Elder of The Galveston County Daily News said "some saw it as a strong sign of Hurricane Ike recovery and welcome investment in the island’s downtown." By January 2012 the restaurant in Galveston had closed. In mid-2012, the three remaining franchised Ninfa's locations owned by Santiago Moreno, in the Kirby Drive area, the Galleria area, and the Interstate 45 Gulf Freeway area, were converted into Maggie Rita's. Katharine Shilcutt of the Houston Press rated the food at the new restaurants negatively and said that "[i]t represents a new nadir for a once-respected and beloved Houston Tex-Mex institution." Shilcutt further added that the takeover caused an "uproar" in Houston and that "to many longtime Houstonians (me [​⁠sic​⁠] included), the deal with interloper Maggie Rita's may as well have been a pact with the devil." As of April 2013 only one Maggie Rita's restaurant remains in operation. Locations The chain had locations in Houston, Galveston, and New Orleans. The Galveston and New Orleans locations closed by 2012. The restaurant's Houston locations included Travis Street/Downtown (the J.P. Morgan Chase Tower in Downtown Houston), Galleria (Uptown Houston, near The Galleria), Hobby (near Hobby Airport), Heights (on Shepherd Drive, near Houston Heights), and Upper Kirby. The Kirby location closed in November 2012. The Galleria location closed the following month. In January 2013, due to rising rents, the Heights location closed. The closures led to 60 employees losing their jobs. Tony Shannard operates the Maggie Rita's in Downtown under a licensing agreement. As of that month, he planned to open another Downtown Maggie Rita's within 30 days, but as of January 2019 the Maggie Rita's website lists only one location. The former Kirby location became the new location of the Houston-area Tex-Mex restaurant Pico's. Concept Santiago Moreno said that the chain differs heavily from Ninfa's, with emphasis on less-filling food and margaritas. Moreno said that the customers "are old Taco Bell clients who grew up with Taco Bell as Mexican food" and that "[t]heir

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.
