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>
the Royal Lincolnshire Regiment and the Sherwood Foresters (Nottinghamshire and Derbyshire Regiment). Glen Parva was downgraded to regimental headquarters. The 1st Battalion served in the Korean War from 1951 to 1952. They subsequently moved to England (exercising the freedom of the City of Leicester in 1952), Germany, Sudan, where they operated with the Sudan Defence Force and departed on 16 August 1955, Cyprus, Brunei and Aden. The Territorial units were reformed in 1947 as 579 (The Royal Leicestershire Regiment) Light Anti-Aircraft Regiment, RA and 5th Battalion Royal Leicesters. In 1961 they merged to become the 4th/5th Battalion. In 1963 the Forester Brigade was dissolved, with the Royal Leicesters and Royal Lincolns moving to the East Anglian Brigade where they joined the 1st, 2nd and 3rd East Anglian Regiments. Amalgamation into the Royal Anglian Regiment On 1 September 1964 the regiments of the East Anglian Brigade became The Royal Anglian Regiment. The 1st Battalion, Royal Leicestershire Regiment became the 4th (Leicestershire) Battalion, The Royal Anglian Regiment. The "Leicestershire" subtitle was removed on 1 July 1968 and the battalion was disbanded in 1975. The Royal Leicestershire heritage was included in the new regiment's button design, which features the royal tiger within an unbroken wreath. When the Territorial Army was converted into the Territorial and Army Volunteer Reserve (TAVR) in 1967, 4/5th Battalion provided two elements: 4th (Leicestershire) Company, 5th (Volunteer) Battalion, Royal Anglian Regiment in TAVR II (units with a NATO role) The Royal Leicestershire Regiment (Territorials) in TAVR III (home defence units). The TAVR regiment was later reduced to B (Royal Leicestershire) Company, 7th (Volunteer) Battalion in the Royal Anglians. In 1978, 4th Coy 5th Bn and B Coy 7th Bn were amalgamated to form HQ (The Royal Leicestershire) Company of 7th Bn Royal Anglians A further reduction in the TA in 1999 saw HQ Company merged with C (Northamptonshire Regiment) Company to form C (Leicestershire and Northamptonshire) Company of the East of England Regiment, which was redesignated 3rd Bn Royal Anglian regiment in 2006. Under the 2020 plans for the Army Reserve, C Company at Leicester will absorb B (Lincolnshire) Company by the end of 2016. Regimental museum The Royal Leicestershire Regiment Museum is part of Newarke Houses Museum in Leicester.

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.
