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>
Chazara briseis Chazara briseis, the hermit, is a butterfly species belonging to the family Nymphalidae. It can be found in North Africa, southern Europe, Asia Minor, the Caucasus, Kazakhstan, Central Asia through Afghanistan, and north-western China and Tuva.It is found on steppe and in other dry grassy places between 500 - 2,500 mtrs The wingspan is 45–60 mm. The butterflies fly from July to September depending on the location. The larvae feed on Sesleria coerulea and Gramineae, Sesleria, Festuca, Stipa, Poa, Brachypodium and Lolium species. Subspecies C. b. briseis includes pirata Esper, 1789 C. b. major (Oberthür, 1876) Morocco, Algeria, Tunisa C. b. meridionalis (Staudinger, 1886) South Europe, West Siberia, Saur, Tarbagatai, Altai, South Siberia C. b. hyrcana (Staudinger, 1886) Kopet-Dagh C. b. fergana (Staudinger, 1886) Ghissar, S.Ghissar, Darvaz, Alai includes marandica Staudinger, 1886 C. b. magna (Rühl, [1894]) North Tian-Shan, Dzhungarsky Alatau C. b. lyrnessus (Fruhstorfer, 1908) C. b. saga (Fruhstorfer, 1909) Dalmatia C. b. armena Jachontov, 1911 Caucasus, Armenian Highland C. b. suusamyra Korb, 2005 Description in Seitz S. briseis L. (= janthe Pall., daedale Bgstr.) {42b). Very variable in size and markings; recognizable by the flat triangular club of the antenna and the pale costal margin of the forewing. The dark wings are traversed by a band which is usually composed of narrow transverse spots, bearing a distinct apical ocellus and a second similar spot before and somewhat below the middle of the distal margin. Band of the hindwing sometimes shaded. On the underside the male has large dark angular spots at the base of both wings, the female having the hindwing beneath generally uniformly brownish or grey; North France, Germany,Austria, Hungary, and the adjacent districts of Russia. — meridionalis Stgr. (42b) is the South-European form, which is especially common on the Mediterranean coasts of Europe. The white spots composing the band of the forewing are broader than in specimens from Central Europe. — magna Stgr. is the from East Europe, which flies also in some districts of Asia Minor; in size like meridionalis , but the band somewhat broader and purer white, especially on the hindwing. — ab. pirata Esp. (42 f) has the size of the previous, but the band is ochreous ; occurs among white-banded specimens in South and East Europe , and Anterior Asia, being especially large in the last country. — major Oberth. (42 c) is still considerably larger than meridionalis, the band of the forewing being much narrower, and differs at a glance from all the other forms of briseis in the hindwing beneath, on which in the male the dark triangular spot at the middle of the hindmargin is wanting and the dark longitudinal spot above the middle of the cell is quite light green-grey and not sharply defined. This large form is locally not rare in North Africa, in the Aures Mts. and the Kabylie. — hyrcana Stgr. (42 b) is similar to magna, the white band on the upperside being very narrow and the underside very conspicuously variegated ; in Persia and various places of Anterior Asia, especially in the Achal-Tekke country. —fergana Stgr. (42c) is the largest form, which has a rather large white band and in the female a reddish grey underside; from Asia Minor and the Pamir. — turanica Stgr. is nearly as large, the band not being very broad and on the hindwing of the male distinctly tinged with red-brown. — maracandica Stgr. (42 b) , from Samarkand, is a medium-sized form which has very much white, the median band of both wings being very broad and in addition the distal margin of the

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.
