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>
Robin Hanbury-Tenison Airling Robin Hanbury-Tenison OBE, FLS, FRGS (born 7 May 1936) is an explorer based in Cornwall. He is President of the charity Survival International and was previously Chief Executive of The Countryside Alliance. Life Hanbury-Tenison grew up on an Anglo-Irish estate in County Monaghan in Ireland, the youngest of five children. In 1959, he married Marika Hopkinson. She became well known for her cookery books. They had two children, Lucy (b. 1960) and Rupert (b. 1970). Marika died in 1982. Hanbury-Tenison and his second wife Louella (née Williams) own a 14th century farmhouse, Cabilla Manor, on Bodmin Moor, which is both their home and a bed and breakfast business. They have a son, Merlin (b. 1985). In 1957 Hanbury-Tenison was the first person to travel overland by jeep from London to Sri Lanka (Ceylon). In 1958 he and Richard Mason became the first to cross South America overland at its widest point. In 1964–65 he made the first river crossing of S America from north to south from the Orinoco to Buenos Aires (at first with Sebastian Snow). In 1968 he took part in the Geographical Magazine Amazonas Expedition by Hovercraft from Manaus to Trinidad. Discussions with the ethnobotanist Conrad Gorinsky led to the foundation of the charity Survival International. In 1971, as Chairman of Survival (and with Marika), he visited 33 Indian tribes in Brazil at the invitation of the Brazilian government and reported on their condition. In 1977–78 he led the Royal Geographical Society's Gunung Mulu expedition to Sarawak, the Society's largest expedition at that time, taking 115 scientists into the rainforest for 15 months. Since 1960 Hanbury-Tenison has farmed over 2000 acres of hill farm on Bodmin Moor in Cornwall with sheep and cattle, diversified with Angora goats, red deer and wild boar from Russia, and later farming energy from wind, solar, water and biomass. In 1982 and 1983 he organised Capital Radio's Venture Days in Battersea Park. From 1995 to 1998 he was CEO of the British Field Sports Society, now the Countryside Alliance. He organised the Countryside Rally, which brought 130,000 people to Hyde Park in July 1997, and the Countryside March when 300,000 marched through London in 1998. In 2015–16 he celebrated his 80th year by undertaking eight challenges, starting with the London Marathon, which raised over £80,000 for Survival International.

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.
