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>
like the Fairy Tale Forest, located in West. When the park reorganized its infrastructure in the late 1990s, adding the Pardoes Promenade (named after Efteling's mascot Pardoes, a court jester) and a central hub called Efteling Brink, it also changed the areas' names. North was changed to Reizenrijk (Travel Realm), West became Marerijk (Fairy Realm), East became Ruigrijk (Adventure Realm), and South became Anderrijk (Other Realm). In 2017 a fifth realm opened in the center of the park called Fantasierijk (Fantasy Realm). Although the park was not built with these divisions in mind and the names may seem cryptic, they do make sense. Perhaps the area most suited to its name is Ruigrijk, where most fast rides like the double-loop roller coaster Python (constructed in 1981) are located. Marerijk is the home to the Fairy Tale Forest and the Fairies of the Droomvlucht, Anderrijk has some rides that are inspired by non-Western cultures (e.g. Fata Morgana and Piraña), while Reizenrijk has the Carnaval Festival ride, which travels through several different 'countries'. The nw Fantasierijk got its name from the new darkride Symbolica: Palace of Fantasy. Efteling was largely built in an existing pine forest located in a rural area, giving it a 'nature park' feeling. Together with its large ponds and gardens, its abundant green space is rather unusual among the world's leading theme parks. Attractions and rides in Efteling and their designers Attractions not operating in winter or when weather is freezing are marked with 1952 - Fairytale Forest (Dutch: Sprookjesbos; Anton Pieck, Peter Reijnders, Ton van de Ven, Henny Knoet, Michel den Dulk, Karel Willemen and Pim-Martijn Sanders) 1954 - Children's Railway (Dutch: Kinderspoor), (pedal trains, Anton Pieck and Peter Reijnders) 1954 - Anton Pieck Square (Dutch: Anton Pieckplein), (square with nostalgic rides, Anton Pieck and Michel den Dulk) 1956 - Stoomcarrousel (carousel, bought from L.

</passage>

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.
