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>
current Mandrake daily comic strip from King Features. Dragon Lady Press reprinted a 1937 Mandrake daily story in Classic Adventure Strips #1. Pacific Comics Club reprinted two Mandrake daily stories from 1938 Feature Books #18 and #23. Nostalgia Press published a hardback book reprinting two 1938 daily stories. Pioneer Comics reprinted a large number of Mandrake stories in comic book form. Comics Revue has reprinted several Mandrake daily and Sunday stories, including first Mandrake daily story and the first Mandrake Sunday story. JAL Publications has reprinted several Mandrake stories Hermes Press has begun reprinting the King comic book series, which will be published in two volumes. Titan Books reprinted the earliest Mandrake Sunday strips in 2016. Titan Books has also started to reprint the daily strips, by Phil Davis, and by Fred Fredericks. In other media Radio Mandrake the Magician was a 15-minute radio serial, which aired on the Mutual Broadcasting System from November 11, 1940, until February 6, 1942. Films In 1939, Columbia produced a 12-part Mandrake the Magician serial, based on the King Features strip, starring Warren Hull as Mandrake and Al Kikume as Lothar. The serial is available on DVD. An unauthorized Mandrake movie produced in Turkey was made in 1967, Mandrake Killing'in Peşinde (Mandrake Chasing Killing) was also known as Mandrake Killing'e Karşı / Mandrake Against Killing), directed by Oksal Pekmezoğlu and starring Güven Erte as Mandrake. Anthony Herrera had the title role in the TV movie Mandrake (1979) with Ji-Tu Cumbuka as Lothar. Magician Harry Blackstone Jr. was featured in the cast. In 2007, Baldwin Entertainment Group and Hyde Park Entertainment purchased rights to make a Mandrake movie to be directed by Mimi Leder. The two companies own the rights to Lee Falk's The Phantom. Jonathan Rhys Meyers was origianally to play the title character with Chuck Russell as director. In 2009, However, Hayden Christensen replaced Rhys Meyers in the title role of the film with Djimon Honsou co-starring and Mimi Leder directing. Warner Bros announced that they are developing the film version of Mandrake. In June 2016, Sascha Baron Cohen was cast as Mandrake. Unproduced films In the 1960s, Federico Fellini, a close friend of Falk, intended to make a Mandrake movie, but the project was never realized. In the early 1980s, within two weeks of signing with his first agent, American filmmaker Michael Almereyda was hired by Embassy Pictures to rewrite a script for Mandrake the Magician. He told Filmmaker magazine that, upon receiving the assignment, he flew to New York City and checked himself into the Chelsea Hotel to work on the rewrite. Three weeks later, he emerged with a new draft, but by then the studio had changed heads, and, in as little time as his revision took, the project was dropped. Television NBC made a pilot for a Mandrake the Magician TV series in 1954, but no other episodes were made. Stage magician Coe Norton starred as Mandrake and Woody Strode as Lothar. Mandrake and Lothar first appeared in animated form with the Phantom, Flash Gordon, and Steve Canyon in 1972 television special The Man Who Hated Laughter. In the animated series Defenders of the Earth (1986–87), Mandrake the Magician teams with fellow King Features adventurers Flash Gordon and The Phantom. Mandrake's best friend and crime-fighting partner Lothar also has a prominent role, as well as a teenage son nicknamed L.J. (Lothar Jr.) who is a martial artist. Mandrake has an adopted son of Asian blood named Kshin, whom he is training as his apprentice and heir. Peter Renaday provided the voice of Mandrake and Buster Jones provided Lothar's. 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.
