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>
D. M. Ananda Dissanayake Mudiyanselage Nandasena alias D. M. Ananda alias Amal Mahattaya (1954–1989) was a senior leader and a politburo member of the Jantha Vimukthi Peramuna (JVP) during the notorious 1987-89 insurrection. At some point he is rumored to have been in control of the JVP organisation. D.M. Ananda was captured by Sri Lankan government forces in 1989 and apparently died in captivity. Early life D.M. Ananda was a native of Wariyapola, North Central Province. He graduated in Arts form the University of Peradeniya in 1980. He entered the university as a Buddhist monk and later switched to engage in political activities. Student leader During his university days, D.M. Ananda was a student activist. He was President of the Socialist Students Union, the student arm of the JVP, and the Secretary of the Inter University Students' Federation (IUSF). He came into prominence in 1981 during the countrywide protest against the government White Paper on Educational Reforms. As the chief organizer of this campaign, which was largely steered by the JVP, thousands of university and other students demonstrated on the streets. As a result of this campaign, the JVP drew radical youths to the movement. Ananda was recognized as a capable organizer. He became the key link between the JVP and the university activists. They played the most vital part of the 1987-89 insurrection and many of the party’s leaders were students or former students. Rise in the party By 1985, some of the top leaders had left the party including Lionel Bopage, Daya Wanniarachchi, Vaas Thilakaratne and Mahinda Pathirana. As a result, young leaders, such as D.M. Ananda, H.B. Herath and Shantha Bandara had the opportunity to move up. Ananda was appointed to the politburo. He was installed as political leader of the Western Zone, which included Western and Sabaragamuwa provinces. In addition, three of the five frontal organisations of the party were under his leadership: students, Bhikku and women. Generally, the JVP politburo is at the apex of the party's hierarchy. It is the main decision-making body and consists of the 12 top most members. During the proscription, politburo members decided, as a safety measure, to convene only in groups of two or three. Ananda played a key role by conveying decisions from one gathering to another. During the 1987-89 insurrection, he was generally ranked third in the JVP after Rohana Wijeweera and Upatissa Gamanayake. However, the movements of Wijeweera and Gamanayake, then the only known leaders to the public, were severely restricted after the 1983 proscription of the party. They were not visible to junior party comrades. This left Ananda as the top person in the JVP. Wijeweera was not superseded as the charismatic leader of the party, but Ananda's scope was much larger than Wijeweera's. Capture and death The Rapid Deployment Force (RDF) of the Sri Lankan Army arrested Raja Mahattaya, the Colombo District division 2 leader, in October 1989. Ananda had been at the location where Mahattaya was captured, but had left several hours earlier. Through information received from Mahattaya, RDF arrested Ananda near Eheliyagoda. Ananda was held at Mattegoda Army camp. After weeks of interrogation and possibly torture, he divulged one important JVP hideout: Araliya Estate in Galaha. A party led by Col. Janaka Perera arrested politburo members Piyadasa Ranasinghe and H.B. Herath, which led to the subsequent arrest of Wijeweera in Ulapane. Ananda apparently died in captivity.

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.
