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>
settled in Kutenai territory in the mid-19th century. They were eventually incorporated into the group and intermarried with them, and spoke the Kutenai language. They departed the Ktunaxa nation in 2004 and are now part of the Shuswap Nation Tribal Council. They are located near Invermere, just northeast of Windermere Lake; their reserves include: St. Mary's #1A, Shuswap IR, ca. 12 km2, population: 244). United States - Idaho Kootenai Tribe of Idaho (ʔaq̓anqmi or ʔa·kaq̓ⱡahaⱡxu, also called Idaho Ksanka). A Lower Kutenai group, they govern the Kootenai Indian Reservation in Boundary County. Their population is 75. United States - Montana Kootenai (K̓upawi¢q̓nuk or Ksanka) are members of the Confederated Salish and Kootenai Tribes, along with Bitterroot Salish and Pend d'Oreilles bands. An Upper Kutenai group, they live mostly on the Flathead Reservation in western Montana. A total population of about 6,800 live on the reservation, while 3,700 live outside the reservation nearby. History The Kutenai today live in southeastern British Columbia, Idaho, and Montana. They are loosely divided into two groups: the Upper Kutenai and the Lower Kutenai, referring to the different sections of the Kootenay River (spelled "Kootenai" in the U.S.) where the bands live. The Upper Kutenai are the Akisqnuk First Nation (Columbia Lake Band), the St. Mary's Band, and the Tobacco Plains Indian Band in British Columbia, as well as the Montana Kootenai. The Lower Kutenai are the Lower Kootenay First Nation of British Columbia and the Kootenai Tribe of Idaho. Origins Scholars have numerous ideas about the origins of the Ktunaxa. One theory is that they originally lived on the prairies, and were driven across the Rockies by the competing Blackfoot people or by famine and disease. Some Upper Kootenay participated in a Plains Native lifestyle for part of the year, crossing the Rockies to the east for the bison hunt. They were relatively well known to the Blackfoot, and sometimes their relations with them were in the form of violent confrontation over food competition. Some Ktunaxa remained on or returned to the prairies year round; they had a settlement near Fort Macleod, Alberta. This group of Ktunaxa suffered high mortality rates, partly because of the depredations of the Blackfoot, and partly because of smallpox epidemics. With numbers sharply reduced, these Plains Ktunaxa returned to the Kootenay region of British Columbia. Some of the Ktunaxa say that their ancestors came originally from the Great Lakes region of Michigan. To date, scholars have not found either archeological or historic evidence to support this account. The Ktunaxa territory in British Columbia has archeological sites with some of the oldest human-made artifacts in Canada, dated to 11,500 before the present (BP). It has not been proven whether these artifacts were left by ancestors of the Ktunaxa or by another, possibly Salishan, group. Human occupation of the Kootenay Rockies has been demonstrated by dated sites with evidence of quarrying and flint-knapping, especially of quartzite and tourmaline. This oldest assemblage of artifacts is known as the Goatfell Complex, named after the Goatfell region about 40 km east of Creston, British Columbia on Highway 3. These artifacts have been found at quarries in Goatfell, Harvey Mountain, Idaho, Negro Lake and Kiakho Lake (both near Lumberton and Cranbrook), North Star Mountain just west of Creston on Highway 3, and at Blue Ridge. All these sites are within 50 km of Creston, with the exception of Blue Ridge, which is near the village of Kaslo, quite a distance north on the west side of Kootenay Lake. Archaeologist Dr. Wayne Choquette believes that the artifacts represented in the Goatfell Complex, dated from 11,500 BP up

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.
