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>
Abyss & Apex Magazine Abyss & Apex Magazine (A&A) is a long-running, semi-pro online speculative fiction magazine. The title of the zine comes from a quote by Friedrich Nietzsche (1844-1900), "And if you gaze long into the abyss, the abyss gazes also into you." The stories and poetry therefore follow the pattern of "how would humans react?" if a new technology or a type of magic or supernatural power affected them. The magazine's title frequently gets confused with Jason Sizemore's Apex Magazine, even though the two magazines are very different. Apex will explore dark science fiction and horror; while Abyss & Apex publishes somewhat dark fiction, they will not publish horror. Instead, Abyss & Apex publishes about fifty percent each fantasy and science fiction. The magazine was issued bimonthly until #13 and thereafter quarterly. Subgenres Per Wendy S. Delmater, "A&A likes to show all the different things speculative fiction can be (except horror)." From their submissions page: "We look for the unique: stories that stand out in a genre that pushes the envelope of unusual. We take special delight in detailed world-building: we like slipstream, YA, hypertext fiction, dark fantasy, science fiction puzzle stories, magical realism, hard science fiction, soft science fiction, science fantasy, urban fantasy, military science fiction, ghost stories, space opera, cyberpunk, steampunk... there is very little we will not look at, although we have a severe allergy to zombies, elves, retold fairy tales, sports, westerns, vampires, and gratuitous sex and violence. We have no subject/topic preference, beyond a requirement that the work have a speculative element. We are happy to read stories that don't quite seem to fit elsewhere." Abyss & Apex has therefore published a rather broad range of subgenres of both science fiction and fantasy, everything from hypertext science fiction to YA fantasy. Past and present editors Abyss & Apex was founded by Carol Burrell, and published by Burrell under the ByrenLee Press imprint, Riverdale, New York. Elizabeth Bear was managing editor from the first issue (January/February 2003), to issue #7 (January/February 2004) with editor Leah Bobet, followed by Kathryn Allen (March/April 2004 #8), Aleta Daknis (to #16 October 2005). From issue #15 onward (January 2006) Wendy S. Delmater has been the managing editor; she also became publisher from #37 (January 2011) when the magazine moved to a WordPress format, via Abyss & Apex Publishing, Lexington, SC. Wendy S. Delmater continues as head editor. Poetry Editors have included Robin Mayhall, Trent Waters, Stephen A. Wilson, and John C. Mannone. Since 2010 Abyss & Apex has had a Flash Editor, Jennifer Dawson, with a staff dedicated to this very short form of fiction. Over the course of their history there have been several assistant editors, most notably Rob Campbell (New Zealand) as Science Fiction Editor and Jude-Marie Green as Associate Editor, and Tonya Liburd as Senior Editor – to date the genre's only Caribbean magazine editor. New and contributing writers Twenty-five percent of the stories Abyss & Apex have published are first-time publications for their authors. Publication in Abyss & Apex also became a cover letter credit for writers that later went on to be well known. Among other well-known names, Abyss & Apex published early Aliette de Bodard, Marie Brennan, Karl Bunker, Paul Carson, Rae Carson, J. Kathleen Cheney, N.K. Jemisin, Lisa Mantchev, Will McIntosh, Tony Pi, Mercurio D. Rivera, Lawrence M. Schoen, and Lavie Tidhar. Abyss & Apex has a policy of trying to publish veteran science fiction and fantasy writers to put their up-and-coming new authors on the same Table of Contents with established people in the genre, thereby giving a boost to

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.
