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>
1857. Along with an increased centralization of the administration under the new regime of Qaym-maqiyamatayn (1842–1860), it contributed to the weakening of the political and economical powers of the sheikhs in the region in general leaving no economic perspectives to the young people. Also, the opening of a school in the neighbouring village of Bane in 1806 by the Lebanese Maronite Order for the basic instruction of the children of Kfarsghab and Bane served as a channel of detection and recruitment of talents and workforce for the Order. The effect was a reduction in the Kfarsghab population. According to a recent study, 344 males lived in Kfarsghab in 1862, that is to say 1,720 inhabitants. The emigration (1870–1899) In the 1870s, vocations among the natives of Kfarsghab started to decrease. Between 1875 and 1900, only 3 vocations were recorded for Kfarsghab. Vocations from Kfarsghab ceased on 17 December 1898 when Br Ephraim Saliba Abboud II joined. Brother Ephraim died on 9 April 1947. Overall, the Lebanese Maronite Order attracted 43 young people from Kfarsghab, making this village the 15th most important contributor to the Order, among the 382 villages that counted monks among their sons. Still in 1900, Kfarsghab counted 13 monks among its sons, representing 4% of the adult male population compared to 0.8% for the average of the region of Jebbet Bsharri. Looking at the names and the monasteries of the monks from Kfarsghab, 75% of them were assigned to monasteries located in North Lebanon, most of them being in Qozhaya. The objective of the reform that took place after the revolt of Qozhaya in 1875 was to assign the monks in a different region from their region of origin. 4 monks of Kfarsghab participated in the 1875 revolt, one of them, brother Boutros, being among its leaders. As a result, the power of Qozhaya was broken, its lands divided between several monasteries and its monks (around 200 at its height) distributed in different Monasteries. It is possible, according to some historians, that this reform could have had a negative impact on the vocations from Jebbet Bsharri. The special status of Mount Lebanon during the Regime of Mutasarrifiah (1861–1914) changed the administration of Kfarsghab which was attached to the distant district of Batroun. The collapse of the prices of silk from the 1870s and onward deteriorated the economic situation. Politically and economically, the Sheikhs of Kfarsghab were weakened. Finally, the loss of interest in the monks order was replaced soon by the emigration to the US and to Australia. Emigration from Kfarsghab to the United States started in 1885, followed by an emigration to Australia in 1887. It resulted in a dramatic decrease in the Kfarsghab population. In 1889, the number of inhabitants was estimated to 1,100. For the year 1900, it is reported 330 male adults, 950 inhabitants and 150 emigrants for Kfarsghab. Kfarsghab lost to the emigration 20% of its population in less than 15 years. This trend will continue in the 20th century.

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.
