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>
Chad–Libya relations Chad–Libya relations have arisen out of centuries of ethnic, religious, and commercial ties. History 1960s Under French and Italian colonial domination, respectively, Chad and Libya had diverged in orientation and development. But even after Chad's independence in 1960, many northerners still identified more closely with people in Libya than with the southern-dominated government in N'Djamena. After seizing power in 1969, Libyan head of state Muammar Gaddafi reasserted Libya's claim to the Aozou Strip, a 100,000-square-kilometer portion of northern Chad that included the small town of Aozou. Libya based its claim on one of several preindependence agreements regarding colonial boundaries, and it bolstered these claims by stationing troops in the Aozou Strip beginning in 1972. Gaddafi's desire to annex the Aozou Strip grew out of an array of concerns, including the region's reported mineral wealth, including uranium. He also hoped to establish a friendly government in Chad and to extend Islamic influence into the Sahel through Chad and Sudan.. Chad's president Hissène Habré was vigorously helped by the ex colonial power, France, which desired to put a limit on Libya's expansion projects in an area with close ties with Paris. French support included sending troops to combat the Libyans in Chadian territory. In doing so, France was politically backed by the United States, also concerned with the increasing expansionism of Gaddafi. A complex set of symbolic interests also underlay Libya's pursuit of territory and influence in the Sahel. Gaddafi's anticolonial and anti-imperialist rhetoric vacillated between attacks on the United States and a campaign focused on the postcolonial European presence in Africa. He hoped to weaken Chad's ties with the West and thereby reduce Africa's incorporation into the Western-dominated nation-state system. Forcing the revision of one of the colonially devised boundaries affirmed by the OAU in 1963 was a step in this direction—one that seemed possible in the context of the troubled nation of Chad, which OAU members dubbed the continent's "weakest link." 1970s Gaddafi attempted alliances with a number of antigovernment rebel leaders in Chad during the 1970s, including Goukouni, Siddick, Acyl Ahmat (a Chadian of Arab descent), and Kamougué, a southerner. Goukouni and Acyl were most sympathetic to Gaddafi's regional ambitions, but these two men clashed in 1979, leading Acyl to form the CDR. After Acyl's death in 1982, Libyan support swung strongly to Goukouni's GUNT. Libya intervened militarily in Chad in 1978 and 1979, starting the Chadian–Libyan conflict. 1980s In 1980, Libya intervened again in Chad's civil war, occupying most of the country including the capital of N'Djamena in December. On 6 January 1981, a joint communiqué was issued in Tripoli by Libyan Brotherly Leader Gaddafi and Chadian rebel leader Goukouni that Libya and Chad had decided "to work to achieve full unity between the two countries". Faced with both strong international condemnation and internal opposition from Chadian rebels, Gaddafi and Goukouni backpedaled, and their relations soon deteriorated when Goukouni tried to accommodate international and internal pressure to end the Libyan military presence. Eventually, on 29 October Goukouni demanded the Libyan forces be retreated by the year's end, and surprisingly quickly Gaddafi complied and had withdrawn all Libyan troops to the Aouzou Strip by 16 November. The FAN rebel faction led by Hissène Habré rose to power and in 1982 ousted Goukouni from N'Djamena, forcing his GUNT faction back to the north. Habré was repelled by GUNT in December and January 1983, however, and eventually Gaddafi decided to support Goukouni's GUNT once more. A new Libyan intervention followed in June, though it was largely through material support of the GUNT offensive. France (under Operation Manta), the US

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.
