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>
impetus of the poem derives from this tension. Representations of the lover's powerlessness to resist his feelings often include lyrically exaggerated violence. The beloved's power to captivate the speaker may be represented in extended metaphors about the "arrows of his eyes", or by referring to the beloved as an assassin or a killer. Take, for example, the following couplets from Amir Khusro's Persian ghazal Nemidanam che manzel būd shab: Sufism Many of the major historical ghazal poets were either avowed Sufis themselves (like Rumi or Hafiz), or were sympathizers with Sufi ideas. Most ghazals can be viewed in a spiritual context, with the Beloved being a metaphor for God or the poet's spiritual master. It is the intense Divine Love of Sufism that serves as a model for all the forms of love found in ghazal poetry. Most ghazal scholars today recognize that some ghazal couplets are exclusively about Divine Love (ishq-e-haqiqi). Others are about "earthly love" (ishq-e-majazi), but many of them can be interpreted in either context. Traditionally invoking melancholy, love, longing, and metaphysical questions, ghazals are often sung by Afghan, Pakistani, and Indian musicians. The form has roots in seventh-century Arabia, and gained prominence in the thirteenth- and fourteenth centuries, thanks to such Persian poets as Rumi and Hafiz, and later to Indian poets such as Mirza Ghalib. In the eighteenth-century, the ghazal was used by poets writing in Urdu. Among these poets, Ghalib is the recognized master. Important ghazal poets Ghazals were written by Rumi, Hafiz and Saadi Shirazi of Persia; the Azerbaijani Turkish poet Fuzûlî in the Ottoman Empire; Mirza Ghalib and Muhammad Iqbal of North India; and Kazi Nazrul Islam of Bengal. Through the influence of Goethe (1749–1832), the ghazal became very popular in Germany during the 19th century; the form was used extensively by Friedrich Rückert (1788–1866) and August von Platen (1796–1835). The Kashmiri poet Agha Shahid Ali was a proponent of the form, both in English and in other languages; he edited a volume of "real Ghazals in English". Ghazals were also written by Moti Ram Bhatta (1866–1896), the pioneer of Nepali ghazal writing in Nepali. Ghazals were also written by Hamza Shinwari, He is known as the father of Pashto Ghazals. Important poets of Persian ghazal In Persian, prominent and acclaimed ghazal poets include Hafiz, Rumi, Saadi Shirazi, Fakhr-al-Din Iraqi, Khwaju Kermani, Saib Tabrizi, Hossein Monzavi, Maryam Jafari Azarmani, Wali Mohammed Wali, Mirza Ghalib, Mir Taqi Mir, Momin Khan Momin, Daagh Dehlvi, Khwaja Haidar Ali Aatish, Jan Nisar Akhtar, Khwaja Mir Dard, Jaun Elia, Faiz Ahmad Faiz, Ahmad Faraz, Firaq Gorakhpuri, Muhammad Iqbal, Syed Amin Ashraf, Qamar Jalalabadi, Shakeb Jalali, Nasir Kazmi, Sahir Ludhianvi, Hasrat Mohani, Makhdoom Mohiuddin, Jigar Moradabadi, Khumar Barabankvi Saghar Siddiqui, Munir Niazi, Mirza Rafi Sauda, Qateel Shifai, Majrooh Sultanpuri, Dushyant Kumar, Syed Waheed Ashraf, Mohammad Ibrahim Zauq, Madan Pal,, Ghulam Abbas Saghar and Kashmiri Lal Zakir, Khumar Barabankvi. Translations and performance of classical ghazal Enormous collections of ghazal have been created by hundreds of well-known poets over the past thousand years in Persian, Turkish, and Urdu as well as in the Central Asian Turkic languages. Ghazal poems are performed in Uzbek-Tajik Shashmakom, Turkish Makam, Persian Dastgah and Uyghur Muqam. There are many published translations from Persian and Turkish by Annemarie Schimmel, Arthur John Arberry and many others. Ghazal "Gayaki", the art of singing or performing the ghazal in the Indian classical tradition, is very old. Singers like Ustad Barkat Ali and many other singers in the past used to practice it, but the lack of historical records make many names anonymous. It was with Begum Akhtar and later

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.
