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>
Richard Grosvenor, 1st Earl Grosvenor Richard Grosvenor, 1st Earl Grosvenor (; 18 June 1731 – 5 August 1802), known as Sir Richard Grosvenor, Bt between 1755 and 1761 and as The Lord Grosvenor between 1761 and 1784, was a British peer, racehorse owner and art collector. He was created Baron Grosvenor in 1761 and in 1784 became both Viscount Belgrave and Earl Grosvenor. Early life Richard Grosvenor was born at Eaton Hall, Cheshire, the elder son of Sir Robert Grosvenor, 6th Baronet. He was educated at Oriel College, Oxford, graduating MA in 1751 and DCL in 1754. Political life He became Member of Parliament for Chester in 1754 and continued to represent the city until 1761, when he became Baron Grosvenor and was elevated to the House of Lords. He was mayor of Chester in 1759 and in 1769 he paid for the building of the Eastgate in the city. Grosvenor extended his estate by the purchase of the village of Belgrave, and the manor of Eccleston in 1769. He succeeded as 7th baronet on the death of his father in 1755. Initially, Grosvenor was, like his father, a Tory, but later he came to support the ideas of William Pitt the elder. In 1758 he declared himself in favour of the Pitt–Newcastle ministry and following this he was created Baron Grosvenor in 1761. However, when the Tory Earl of Bute became Prime Minister the following year, Grosvenor changed his allegiance. Then, when Pitt was returned to power in the Chatham Ministry of 1766–68, Grosvenor returned to support him. During the 1770s he supported Lord North during the American War of Independence. He voted against Fox's India Bill in 1783 and was rewarded by William Pitt the Younger with title of Earl Grosvenor the following year. Personal interests Otherwise, Grosvenor was interested in the acquisition of art and in horse racing. He was also the principal patron of the satirist and journalist William Gifford. For his art collection he acquired works from Italy, and also bought paintings from Benjamin West (including his painting of The Death of General Wolfe), Thomas Gainsborough, Richard Wilson and George Stubbs. In 1788 a collection of literary pieces composed at Eaton was published as The Eaton Chronicle, or The Salt-Box. Grosvenor was appointed as a Fellow of the Royal Society in 1777. To breed his race horses Grosvenor established studs at Wallasey and at Eaton. His horses won the Derby on three occasions and the Oaks six times. His racing silks were yellow, with a black cap. In the 1760s, Grosvenor occupied Aubrey House, in the Campden Hill area of Holland Park. A London County Council blue plaque commemorates Grosvenor and other residents of the house. Family On 19 July 1764 Grosvenor married Henrietta Vernon, daughter of Henry Vernon of Hilton Park, Staffordshire; they had four sons. However the marriage was not happy, and Henrietta had an affair with Henry, Duke of Cumberland, the younger brother of George III. The couple were discovered in flagrante delicto in 1769, which led to Grosvenor bringing an action against the Duke for "criminal conversation" (that is, adultery). He was awarded damages of £10,000, which together with costs, amounted to an award of £13,000 (£ in 2015). But Grosvenor was also known to be guilty of adultery himself, regularly seeking out prostitutes around Leicester Square, so he could not sue for divorce. The couple separated and he settled an annual allowance of £1,200 (£ in 2015) on his estranged wife, who entered the demi-monde and was a leading member of The New Female Coterie. Death Grosvenor died at Earls

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.
