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>
Wells himself (Tom Ward) as the main protagonist in each story. In the Disney Channel Original Series Phil of the Future, which centres on time-travel, the present-day high school that the main characters attend is named "H. G. Wells". In the 2006 television docudrama H. G. Wells: War with the World, Wells is played by Michael Sheen. Television episode "World's End" of Cold Case (2007) is about the discovery of human remains in the bottom of a well leads to the reinvestigation of the case of a housewife who went missing during Orson Welles' radio broadcast of "War of the Worlds". On the science fiction television series Warehouse 13 (2009–2014), there is a female version Helena G. Wells. When she appeared she explained that her brother was her front for her writing because a female science fiction author would not be accepted. Comedian Paul F. Tompkins portrays a fictional Wells as the host of The Dead Authors Podcast, wherein Wells uses his time machine to bring dead authors (played by other comedians) to the present and interview them. H. G. Wells as a young boy appears in the Legends of Tomorrow episode "The Magnificent Eight". In this story, the boy Wells is dying of consumption but is cured by a time-travelling Martin Stein. In the four part series The Nightmare Worlds of H. G. Wells (2016), Wells is played by Ray Winstone. In the 2017 television series version of Time After Time, based on the 1979 film, H. G. Wells is portrayed by Freddie Stroma. In the 2019 television adaptation of The War of the Worlds, the character of 'George', played by Rafe Spall, demonstrates a number of elements of Wells' own life, including his estrangement from his wife and unmarried co-habitation with the character of 'Amy'. Literary papers In 1954, the University of Illinois at Urbana–Champaign purchased the H. G. Wells literary papers and correspondence collection. The University's Rare Book & Manuscript Library holds the largest collection of Wells manuscripts, correspondence, first editions and publications in the United States. Among these is unpublished material and the manuscripts of such works as The War of the Worlds and The Time Machine. The collection includes first editions, revisions, translations. The letters contain general family correspondence, communications from publishers, material regarding the Fabian Society, and letters from politicians and public figures, most notably George Bernard Shaw and Joseph Conrad.

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.
