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>
Juan dela Cruz (TV series) Juan dela Cruz is a 2013 Philippine superhero television series starring Coco Martin. The drama series is broadcast in full high definition and is dubbed to be ABS-CBN's "most expensive and biggest drama" to date. It is created by Rondel P.

A TV special titled "Juan dela Cruz: Ang Simula (The Beginning)" was aired on February 1, 2013 featuring exclusive behind-the-scenes footage and cast interviews of the highly anticipated drama, hosted by Kim Atienza. Plot The Tagabantay (Guardian) is a hero coming from an ancient lineage of defenders using the Bakal na Krus (Iron Cross) to protect the humans from the Aswang, who are strange creatures that appear as ordinary people to hide their real identities; they spread evil, kill, and eat people. The Bakal na Krus transforms into five weapons, namely: Espada ng Katapangan (Sword of Bravery), Pana ng Karunungan (Bow of Wisdom), Latigo ng Katarungan (Whip of Justice), Sibat ng Kagitingan (Spear of Courage), and the Kalasag ng Anking Galing (Shield of Aptitude). The Aswangs and Tagabantay are mortal enemies. The story begins when Samuel Alejandro (Albert Martinez), the Haring Aswang (King Aswang), plans to make Amelia (Mylene Dizon), a Tagabantay, fall for him so he could kill her and finally provide triumph for his race. However, he falls in love with her as well, betraying his entire race. Upon knowing his secret, Amelia and Samuel try to kill each other but Samuel chooses to escape instead of killing her—even if that’s what he should do as an Aswang. Juan's Beginnings Samuel has no idea that he has a child with Amelia, who dies right away after giving birth to her son. Before she dies, she managed to tell the boy’s real identity as a half-Tagabantay and half-Aswang to a Roman Catholic parish priest named Father Cito (Jaime Fabregas). She strictly reminded him to raise the child in goodness, to be far from his father’s evil influence that he carries within his

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.
