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>
the Chakavian subdialects of the Southeastern group. Speaking area According to Pliško, the subdialect is spoken "from the very South (Premantura), along the Western coast of Istria until the delta of river Mirna (Tar), along Eastern line Muntrilj – Kringa – Sveti Petar u Šumi – Kanfanar until Sveti Ivan in Višnjan, along Western coast of river Raša until Barban, then line Rakalj – Marčana – Muntić – Valtura – and South Jadreški – Šišan – Ližnjan – Medulin". To this subdialect also belongs the so-called Vodice oasis of ten villages (Vodice, Jelovice, Dane, Trstenik, Rašpor, Črnehi located in municipality of Lanišće, and Golac, Brdo, Gojaki, Zagrad in municipality of Hrpelje-Kozina) in Northeastern part of Istria (Ćićarija), located in Croatia and Slovenia, which was described by Ribarić. It can be divided into smaller units: the main area in the Southwest, Premantura area in the South, and Vodice oasis in the Northeast. From the prosody perspective of accent, rhythm, intonation, etc., it can be divided into typological areas: central, border, northwestern, Vodice oasis, southern. Main features In this subdialect the yat is i (Ikavian): lip, divojka, mriža, srića, in comparison to Shtokavian Ijekavian lijep, djevojka, mreža, sreća. It has little Ekavian which is mainly a borrowing from neighbouring Istrian Chakavian subdialects or from Slovenes dialects. It is mostly Shtakavian ("ognjište", "dažditi"), but it is not generally because Šćakavian examples are not rare. Chakavian features are partly of Southeastern and Southwestern type, brought and received in Istria. Josip Lisac quotes these features; "sequence w + semitone give partly u- in Shtokavian way, which is also in Chakavian Southeast, for e.g. u, unuki. Partly is Vazam 'Uskrs', vajka 'uvijek', valje 'odmah', and that is Chakavian result, specifically Northwestern Chakavian subdialects. Dočetno -l mainly regularly gives a, which is Shtokavian feature, however, it is also well represented in Chakavian under strong influence of Shtokavian. Especially interesting are reflexes prsl. ď, was it j, đ, ď, ž, also type mlajži. Example of type mlaži actually are Shtokavian result (dž) spoken in a Chakavian way. J is Chakavian represented in many Western Shtokavian dialects. Phoneme h mainly is well conserved, but there are also deviations ... Usually, it is everywhere except around Premantura conserved čr-, as it is common in Chakavian, exceptionally in Shtokavian. Usually are a regular short plural of single-word nouns of masculinity, as it is in Chakavian and Kajkavian, sometimes also in Shtokavian. Generally is said for e.g. dva kantuna, tri kantuni, četiri kantuni, as it is common in Chakavian. Characteristically are substitute words ča i zašto, ča probably as acquired feature, zašto as old. Distinct Chakavian element bin, biš, bi, bimo, bite, bi characterize the subdialect, even in Premantura in the South there's bimo and bite". Accentuation is different depending on the place although there are some common features. It has a three-tone system, while in the area of Vodice oasis is two tonic (except in the village of Trstenik where is one tonic, similar to the Buzet dialect). According to general features, it is part of a dialectical continuum and the encounter of Western Shtokavian and Southern Chakavian, with several divisions within the subdialect older than the 16th-century migration to Istria. According to Lisac, it was primarily formed "in the hinterland of Makarska Riviera. That's the territory where predominantly was spoken Shtokavian, slightly Chakavian, and main features are Štakavism and "-a" in verb adjective in working, along non-Neoshtokavian accentuation ... The place of origination was not located by the sea (because it would be Šćakavian), but also not very far from the sea (because it would have "-l" instead of "-a").

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.
