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>
and Dormammu are ultimately imprisoned in Dormammu's dimension. In the series finale, its second host appeared as Spider-Carnage. The Carnage symbiote appears in the Spider-Man Unlimited animated series, voiced by Michael Donovan (Cletus Kasady). Like Venom, this version had the ability to change into a somewhat liquid form while the default appearance changes to appear taller, skinnier, and with boney protrusions. The Carnage symbiote was originally slated to appear if The Spectacular Spider-Man animated series had been renewed for a third season, but never appeared. Cletus Kasady however, does make a cameo in the Ravencroft Institute during a therapy session with other patients while wearing a Santa Claus hat. The Carnage symbiote appears in the Ultimate Spider-Man animated series, voiced by Dee Bradley Baker (humanoid form), and by Fred Tatasciore (various hosts and giant form). The first version is a mutated form of the Venom symbiote. In its self-titled episode "Carnage", the original version is created when the Green Goblin injects Peter Parker with a symbiote sample to be a perfect Venom but Peter's spider cells makes an unstable organism that has a spiked tongue, makes screeching noises and can cause spikes to protrude from all over his body until Harry Osborn's sacrifice. The second iteration later appears in Ultimate Spider-Man vs. The Sinister Six as a completely different creature. This version is the main focus in "The Symbiote Saga" three-parter as a weaponized symbiote for HYDRA. Created by Michael Morbius, the Carnage symbiote envelops Doctor Octopus as a host after Morbius is injected with Doc Ock's vampire bat serum, eventually being separated by Spider-Man and Flash Thompson. Upon gaining its own sentience as a hostless symbiote, Carnage fights with Spider-Man and Agent Venom which results in a symbiote bomb to spread to possesses multiple hosts (such as the Hulk and Shriek) until the Anti-Venom symbiote ultimately neutralized Carnage's swarm. However, Carnage's regenerated in a giant form that turned in a hive that Spider-Man, Agent Venom, and Patrioteer fought through in order to find the Carnage Queen in the center. The Carnage symbiote appears in the Guardians of the Galaxy animated series. It's seen in the episodes "Back in the New York Groove" and "Drive My Carnage". The Carnage symbiote alludes in the live-action series Jessica Jones; Karl Malus wears a pair of red glasses, which is a reference to Superior Carnage. Film Woody Harrelson will portray the Cletus Kasady version of Carnage in Venom 2, which is scheduled for release in the United States on October 2, 2020. Video games The Cletus Kasady version of Carnage was a boss character in The Amazing Spider-Man 2 (1992), Spider-Man/X-Men: Arcade's Revenge, The Amazing Spider-Man: Lethal Foes, and Spider-Man and Venom: Maximum Carnage, Venom/Spider-Man: Separation Anxiety, and Spider-Man (2000) (voiced by Dee Bradley Baker). In the 2000 Spider-Man video game, Carnage (Cletus Kasady) is helping Doctor Octopus with his plan to infest New York with symbiotes, which are cloned from Carnage's symbiote. Carnage serves as the game's penultimate boss and is fought immediately after defeating Doc Ock. After Spider-Man defeats Carnage using sonics, the symbiote attaches to Doctor Octopus instead, turning him into an out-of-control monster called Monster-Ock, which serves as the game's final boss. Monster Ock is too powerful to be fought directly, so Spider-Man is forced to run away from him through the underwater base. After a long chase, Monster Ock ends up destroying the entire base and is caught in the explosion, which removes the symbiote from Doctor Octopus. The Ultimate Marvel iteration of the Carnage symbiote appears as the penultimate boss in the Ultimate Spider-Man video game. Unlike

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.
