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>
Yirandhali The Yirandhali were an indigenous Australian people, who lived in the area of the present day Shire of Flinders in the state of Queensland. Language Yirandhali may possibly. according to Robert Dixon, belong to the Maric branch of the Pama–Nyungan language family. According to Peter Sutton, the list of words given by an early settler, M. Armstrong of the language of the Upper Cape River, which Tindale ascribes to the Yilba, actually refers to the Yirandhali language. Country The Yirandhali had an estimated territorial estate, according to Norman Tindale, of around . The heartland of their country lay west of the Great Dividing Range, around the upper Dutton and Flinders rivers and stretched from near Mount Sturgeon southwards as far as Caledonia. Their western limits lay close to Richmond, Corfield, and the area east of Winton. The Yirandhali were the indigenous peoples of Torrens, Tower Hill, and Landsborough Creeks, of Lammermoor, Hughenden and Tangorin. Watering on Yirandhali territory was in good part based on the resources of Towerhill Creek, which, running south, provided 12 'reaches' or watering holes: Pilmunny, Beroota, Marrikanna, Narrkooroo, Narkool, Newjenna, Turrummina, Mattamundukka, Teekalamungga, Teekaloonda, Kooroorinya, and Bogunda,. The wells had been dug, maintained and kept in good repair by the tribe 'since time immemorial'. Social organization The Yirandhali marriage system recognized 4 classes: Ko-bro. Woonggo. Bunberry. Koorookill. History of contact Yirandhali lands were expropriated for running sheep and cattle, after the Scottish immigrant William Landsborough passed through their land. Our main informant for the earliest period is Robert Christison who took up an extensive tract of land for pastoral purposes between the Landsborough and Thomson rivers, reckoned their numbers at about 300. The editor of his papers, and his biographer, his daughter Mary Montgomerie Bennett, writing in 1927 states however that when Christison took up the Yirandhali lands in 1863, they numbered 500. His daughter describes his first contact in the following terms: One day, with Gailbury, overtaking some blacks, he chose a fine-looking young fellow and rode after him, heading him back from the scrub that he was making for to the open plain. In desperation the black fellow ran up a tree. Christison dismounted and signed to him to come down, else he would cut down the tree. Thereupon the black fellow sprang to the ground and threw his arms round the horse's neck, supplicating the terrified animal that snorted and backed, broke the reins, and galloped off. Christison had a difficult task to hold the black fellow, for he was very strong, with muscle like whipcord, slippery with emu oil, and wriggled like an eel. However, he secured the black fellow and brought him home and chained him to a verandah post. He fed him, gave him a blanket, taught him to smoke, and succeeded in convincing him of his friendly intentions, while he picked up what he could of the black fellow's language and learnt the name of the tribe-Dalleburra-and of the black fellow - Ko-bro.' In Dr. J. Beddoe's account, Christison was, uncharacteristically, for the time, much impressed by the capacities and intelligence of the people on whose lands he established his station:- Within a few years of his settlement on the lands he occupies, where he was the earliest European invader, he succeeded in establishing friendly relations with a tribe who had dwelt there, called Dalleyburra.. and by a judicious mixture of firmness, justice and kindness, established himself as their ruler. Considerable numbers of them have been employed since then, in tending herds, sheep and cattle, in sheep-washing, bark-stripping, timber- cutting, and various other occupations. Beddoe, Christison's brother-in-law, reports

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.
