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>
Claverdon Claverdon is a village and civil parish in the Stratford district of Warwickshire, England, about west of the county town of Warwick. Claverdon's toponym comes from the Old English for "clover hill". The hill is near the centre of the scattered parish which includes the township of Langley to the south, and formerly comprised the manors of Claverdon, Langley, Kington (to the south-west), and Songar (in the south-east). There are hamlets near the church and at Yarningale, Kington, Lye Green, and Gannaway; and there is also a group of houses near the school. It includes modern development along with historic buildings: the forge; The Stone Building; St Michael's Church; and 16th and 17th century half-timbered cottages. History The Manor of Claverdon is recorded in the Domesday Book as part of the lands of the Count of Meulan, Robert of Beaumont who had inherited Meulan through his mother. It states; "In Ferncombe Hundred, (Clavendone) Claverdon, Bovi held it; he was a free man. 3 hides. Land for 5 ploughs. In lordship 1. 12 villages with a priest and 14 smallholders have 5 ploughs. 3 slaves. Meadow, 16 acres; woodland, 1 league; when exploited, value 10s. The value was 40s; now £4." The estate passed to the Earls of Warwick when Robert's brother, Henry, keeper of Warwick Castle since 1068, was created Earl of Warwick soon after 1086 and was granted Robert's Warwickshire lands, shortly after supplemented again by those of Thorkell of Arden. It was forfeited in 1397 by Thomas de Beauchamp, 12th Earl of Warwick, for treason and granted, to Thomas, Earl of Kent, but restored to the Earl on the accession of Henry IV. In 1487 it came to the Crown and passed through various hands, being leased in 1517 for 21 years to Thomas Sherwyn, and its demesnes to Roger Walford, In, December 1547, the lordship was granted to John Dudley, Earl of Warwick, after whose execution the manor, in June 1554, was assigned to his widow Joan for life. Ambrose Dudley, fourth son of the Duke of Northumberland, was created Earl of Warwick in 1561 and received the Warwick estates, including the manor of Claverdon, which he sold in 1568 to Sir John Spencer, a member of a branch of the Spencer family, from whom Diana Princess of Wales was descended. They remained Lords of the Manor until 1716. Sir John died 8 November 1586, having settled the manor on his second son Thomas, who died in 1630 and Claverdon passed, to his greatnephew Sir William Spencer of Yarnton,Oxfordshire, Baronet. Sir William in 1635 married Constance daughter of Sir Thomas Lucy and Alice Lucy (née Spencer) of Charlecote Park, and dying in 1647 was succeeded by his son Sir Thomas Spencer, Baronet, M.P. Sir Thomas died on 6 March 1685 at the age of 46 years without surviving male issue, his widow Jane survived till 20 April 1712 as lady of the manor, but after her death the manor was sold about the year 1716 by the four surviving daughters, to Andrew Archer of Tanworth. Upon the death of Andrew Archer in 1741 the larger portion of his estate including the manor of Claverdon and the chief farms therein known as Park, Lodge, Breach, Gannaway, and the Reddings descended to his eldest son Thomas, created first Baron Archer of Umberslade in 1747. Economy Whilst there are no large employers in the area, most residents commuting to larger towns nearby, there are a number of small businesses locally.

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.
