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>
capture of Cyrenaica in 641, reasserted Muslim influence in the Fezzan region, capturing the Zawila oasis and the Garamantes capital of Germa. He may have raided as far south as Kawar in modern-day Niger. The struggle over the succession of Constantine IV drew Byzantine focus away from the African front. In 670, Mu'awiya appointed Uqba as Egypt's deputy governor over the North African lands under Arab control west of Egypt and, at the head of a 10,000-strong force, Uqba commenced his expedition against the territories west of Cyrenaica. As he advanced, his army was joined by Islamized Luwata Berbers and their combined forces conquered Ghadamis, Gafsa and the Jarid. In the last region he established a permanent Arab garrison town called Kairouan a relatively safe distance from Carthage and the coastal areas, which had remained under Byzantine control, to serve as a base for further expeditions. It also aided Muslim conversion efforts among the Berber tribes that dominated the surrounding countryside. Mu'awiya dismissed Uqba in 673, likely out of concern that he would form an independent power base in the lucrative regions that he conquered. The new Arab province, Ifriqiya (modern-day Tunisia), remained subordinate to the governor of Egypt, who sent his mawlā (non-Arab, Muslim freedman) Abu al-Muhajir Dinar to replace Uqba, who was arrested and transferred to Mu'awiya's custody in Damascus. Abu al-Muhajir continued the westward campaigns as far as Tlemcen and defeated the Awraba Berber chief Kasila, who subsequently embraced Islam and joined his forces. In 678, a treaty between the Arabs and the Byzantines ceded Byzacena to the Caliphate, while forcing the Arabs to withdraw from the northern parts of the province. After Mu'awiya's death, his successor Yazid reappointed Uqba, Kasila defected and a Byzantine–Berber alliance ended Arab control over Ifriqiya, which was not reestablished until the reign of Caliph Abd al-Malik ibn Marwan (). Nomination of Yazid as successor In a move unprecedented in Islamic politics, Mu'awiya nominated his own son, Yazid, as his successor. The caliph likely held ambitions for his son's succession over a considerable period. In 666, he allegedly had his governor in Homs, Abd al-Rahman ibn Khalid, poisoned to remove him as a potential rival to Yazid. The Syrian Arabs, with whom Abd al-Rahman ibn Khalid was popular, had viewed the governor as the caliph's most suitable successor by dint of his military record and descent from Khalid ibn al-Walid. It was not until the latter half of his reign that Mu'awiya publicly declared Yazid heir apparent, though the traditional Muslim sources offer divergent details about the timing and location of the events relating to the decision. The accounts of al-Mada'ini (752–843) and Ibn al-Athir (1160–1232) agree that al-Mughira was the first to suggest that Yazid be acknowledged as Mu'awiya's successor and that Ziyad supported the nomination with the caveat that Yazid abandon impious activities which could arouse opposition from the Muslim polity. According to al-Tabari, Mu'awiya publicly announced his decision in 675/76 and demanded oaths of allegiance be given to Yazid. Ibn al-Athir alone relates that delegations from all the provinces were summoned to Damascus where Mu'awiya lectured them on his rights as ruler, their duties as subjects and Yazid's worthy qualities, which was followed by the calls of al-Dahhak ibn Qays and other courtiers that Yazid be recognized as the caliph's successor. The delegates lent their support, with the exception of the senior Basran nobleman al-Ahnaf ibn Qays, who was ultimately bribed into compliance. Al-Mas'udi (896–956) and al-Tabari do not mention provincial delegations other than a Basran embassy led by Ubayd Allah ibn Ziyad in 678/79 or 679/80, respectively, which

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.
