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>
Xewkija Xewkija (, , pronounced and written as Casal Sceuchia) is a village on Gozo Island, Malta. The population of Xewkija is 3,300 as of March 2014, which is the fourth largest in Gozo, after Victoria (6,901), Xagħra (4,886) and Nadur (4,509). History Xewkija, which is situated between Għajnsielem and the capital city, Victoria, is the oldest village in Gozo. It became the first parish outside Victoria on 27 November 1678. It was separated from the Matrix by Bishop Glormu Molina and Dun Grezz Farrugia from Valletta, became its first parish priest. It became the first district 'contrada' to be known as 'casale' or village. The name is derived from the Maltese word "", meaning "thistles" or "thorns". Xewkija is famous for its church, The Rotunda of Xewkija, which is dedicated to St. John the Baptist. It is the Seat of the Knights of the Order of St. John, and was built from Maltese stone by local masons and craftsmen. It is the largest in Gozo and its dome dominates the village. Its architect was Joseph D'Amato. It replaced an older church. The titular statue of Saint John the Baptist was sculpted in wood by Pietro Paolo Azzopardi in 1845. On the site where the present church is, it was said that there was a stone known as 'Maqgħad ix-Xiħ'. Near it there is a small ancient chapel known as Madonna tal-Ħniena (Our Lady of Charity) which was dedicated to San Bartilimew. The Santa Cecilia Tower had been in the limits of Xewkija. There is another tower with the oldest sundial in Xewkija. Remains of Tinghi Tower disappeared in the 20th century. These towers date back to 1613. The Gourgion Tower, which was built in 1690, was demolished during the Second World War to make way for a temporary airstrip. The Majmuna Stone with an Arabic inscription dating back to 1174 was possibly found in Xewkija. It commemorates the death of an Arab girl named Maymūnah. The inscription is carved in a thick marble slab, on the underside of which there is a Roman symbol. Brother Gabrijel D'Alappo translated it into Italian and it was later translated into Maltese. It was sent to the Public Library in Malta in 1845 and brought to the Gozo Museum of Archaeology in 1960. The Banda Prekursur (Precursor Band) is the oldest organization in Xewkija. It was set up on 13 May 1929. Lorenzo Zammit Haber, Marcell Mercieca, Giuseppe Buttigieg, Giovanni Haber and Tomaso Attard were among its founders. Mr. Lorenzo Zammit Haber was first President and Secretary. The coat of arms of Xewkija is a shield on a gold background with a red horizontal strip between two thorns, one above and one below. The motto of Xewkija is 'Nemo me impune lacessit', that is, 'No one shall attack me with impunity'. A helicopter service once ran between Malta International Airport and the Xewkija Heliport. Facilities On the suburbs of the village there are the University of Malta (Gozo Campus) and the offices of the Employment & Training Corporation. There are also the Gozo Stadium, the Government Farm, St. Mary's Cemetery and Xewkija Cemetery. There is also an industrial estate which employs hundreds of Gozitan workers. The rising population in Xewkija needed more building sites for houses and housing estates have been developed at Tal-Barmil, Ta' Ġokk and Tal-Ħamrija. On entering the village from the main road, one sees the remains of the Tat-Tmien Kantunieri Windmill erected in the times of Grand Master Ramon Perellos y Roccaful. This is unique mill in Gozo because it has points which show the eight principal wind directions.

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.
