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>
Eastern Pennsylvania Conference (PIAA) The Eastern Pennsylvania Conference (known informally as EPC, EPC18 and East Penn Conference) is an athletic conference consisting of 18 large high schools from Lehigh, Monroe, Northampton, and Pike counties in the Lehigh Valley and Pocono Mountains regions of Pennsylvania, in the United States. It is a part of District XI of the Pennsylvania Interscholastic Athletic Association (PIAA). The East Penn Conference is broadly considered one of the most competitive athletic divisions in the nation, holding many Pennsylvania and national records and milestones in high school athletic competition. Many East Penn Conference athletes have gone on to compete in the Olympics and in professional sports, including the MLB, NBA, and NFL, and its high school wrestling programs have been labeled "among the nation’s best in the sport for nearly three decades." History See also: Lehigh Valley Conference & Mountain Valley Conference On October 2, 2013, the Lehigh Valley Conference, consisting of 12 schools from the Lehigh Valley, voted to invite the six remaining Mountain Valley Conference schools to the conference, expanding it to a large 18-school "super conference." With the merger taking place, the EPC was officially introduced on June 4, 2014, with play starting in the 2014-15 school year. High schools The 18 high school teams in the Eastern Pennsylvania Conference (with location in parentheses) are: Mountain Division East Stroudsburg High School North Timberwolves (Lehman Township) East Stroudsburg High School South Cavaliers (East Stroudsburg) Pleasant Valley High School Bears (Chestnuthill Township) Pocono Mountain East High School Cardinals (Paradise Township) Pocono Mountain West High School Panthers (Tobyhanna Township) Stroudsburg High School Mountaineers (Stroudsburg) Skyline Division Allentown Central Catholic High School Vikings (Allentown) Emmaus High School Green Hornets (Emmaus) Nazareth Area High School Blue Eagles (Nazareth) Northampton Area High School Konkrete Kids (Northampton) Parkland High School Trojans (South Whitehall Township) Whitehall High School Zephyrs (Whitehall Township) Steel Division Bethlehem Catholic High School Golden Hawks (Bethlehem) Dieruff High School Huskies (Allentown) Easton Area High School Red Rovers (Easton) Freedom High School Patriots (Bethlehem) Liberty High School Hurricanes (Bethlehem) William Allen High School Canaries (Allentown) Current Champions Below is a list of EPC Champions for the 2017–18 school year.

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.
