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>
When Dasgupta returned after his release from jail, the relations with the former RWP cadres deteriorated. Dasgupta had evolved into a Nehru supporter. In the Indo-China war of 1962 RCPI supported the Nehru government, a move the Trotskyists opposed. As a result of the dispute over the Indo-China war, the Trotskyists broke with RCPI in 1963. Dasgupta himself parted ways with RCPI, moving towards a Gandhian position. 1967 elections Kumar served as convenor of the United Front formed ahead of the 1967 West Bengal Legislative Assembly election. Anadi Das lost his assembly seat in the election. During the protests against the dismissal of the first United Front cabinet in 1967, Kumar was arrested under the Preventive Detention Act. RCPI won 3 seats in the first Howrah Municipal Corporation polls, held in 1967. Md. Shamsul Huda of RCPI won the Dhing seat in the 1967 Assam Legislative Assembly election. In the Second United Front government After the 1969 West Bengal Legislative Assembly election Kumar was named Food and Supplies Minister in the second United Front state government. The Food Minister had been given to the Communist Party of India (Marxist) in the coalition government, but CPI(M) opted to name Kumar as its choice for the post. The RCPI won two seats in the 1969 West Bengal Legislative Assembly election. Kumar was named convenor of the United Front as well as being named Food Minister in the Second United Front Cabinet. After Kumar's entry into the West Bengal state cabinet, the two RCPI legislators, Anadi Das and M. Mokshed Ali, revolted against Kumar's leadership. In July 1969 the two legislators were expelled from RCPI, accused of "anti-Party and anti-UF activities". The expulsion provoked a split in RCPI, with Anadi Das leading his own RCPI faction. 1970s After the fall of the United Front cabinet, the RCPI joined the CPI(M)-led United Left Front. The front, which was formally constituted in May 1970, had Kumar as its convenor. In the 1971 West Bengal Legislative Assembly election RCPI won three seats; Bimalananda Mukherjee in Santipur, Sudhindranath Kumar in Howrah Central and Trilochan Mal in Hansan. In the 1971 Indian general election RCPI and CPI(M) had an electoral understanding in Assam. RCPI fielded three candidates in the 1971 Lok Sabha election; two in Assam and one in Bihar. In the Nowgong constituency Baneswar Saikia obtained 32,619 votes (14.34%). In the Jorhat constituency Khogen Bar Barua finished in second place with 31,810 votes (17.10%), challenging Tarun Gogoi. In Bihar, Lakshmi Narayan Singh contested the Katihar seat and obtained 1,193 votes (0.43%). In the 1972 West Bengal Legislative Assembly election RCPI fielded its three incumbent legislators; Mukherjee, Kumar and Mal. All three were defeated, gathering 47038 votes (0.35% of the statewide vote). Whilst RCPI lost its Dhing seat in the 1972 Assam Legislative Assembly election, it managed to score an impressive victory against Dharanidar Chowdhury in Bhabanipur constituency. The Bhabanipur legislator was Ghanakanta Boro. As of the mid-1970s RCPI published the Bengali weekly Mat-o-Path and the Bengali fortnightly Janasadharan, both issued from Calcutta. RCPI fielded a single candidate in the 1974 Orissa Legislative Assembly election. Sarangdhar Muduli, a trade unionist, contested the Sukinda seat and obtained 478 votes (1.21%) 1977 elections Ahead of the 1977 Indian general election RCPI was one of the six founding parties of the CPI(M)-led West Bengal Left Front. The Left Front contested the general election in West Bengal with an electoral understanding with the Janata Party. But whilst CPI(M) was supportive of the Janata Party in Assam in the 1977 Lok Sabha election, RCPI considered the Janata Party and the Congress(I) equally dangerous.

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.
