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>
1999 and sited in an Art Nouveau building on Rua de Camões across from Parque D. Carlos I, contains exhibits on the history of cycling and bicycles. Traditions Caldas da Rainha is well known for its glazed ceramic pottery (louça das Caldas). The New York Times has called Caldas "[t]he capital of Portuguese pottery". The city is at "the center of a region rich in clay", where pottery has been made since the Neolithic Era. Caldas gained fame for its ceramic wares when Rafael Bordalo Pinheiro and his brother Feliciano founded their Fábrica de Faianças, now called Faianças Artísticas Bordallo Pinheiro. The factory's output includes large decorative pieces; tableware shaped like fruits, vegetables, and animals; and figurines of Zé Povinho, a bearded peasant everyman character. Caldas has a tradition of ceramic phalluses dating to the late 19th century. Caldas has a tradition of embroidery (bordado) possibly dating to the 15th century. Legend has it that Queen Leonor's handmaidens, seeing the monarch without her usual brilliance after selling off her jewellery, embroidered her cloak so that it appeared to have golden threads. Caldas embroidery is almost always made with three shades of molasses brown thread on white linen, and on rare occasion with white thread on brown linen. Known for its symmetry, the craft's common themes include arachnids, spirals, angles, birds, hearts, crowns, and shrimp nets. Caldas has several traditional sweets. Cavacas das Caldas are a small-bowl-sized, concave confection of flour and eggs, with a crunchy sugar covering. In June 2005, a pyramid containing 48,900 cavacas was erected on Praça 25 de Abril in front of the city hall. Beijinhos das Caldas ("little kisses") are similar, but are smaller and spherical. Other local sweets include trouxas de ovos (poached eggs), lampreias de ovos (egg lampreys), and pão-de-ló do Landal (Landal sponge cake). Savory dishes typical of Caldas include ensopado de enguias da lagoa (stewed lagoon eels), bacalhau à lagareiro (cod in olive oil), polvo à lagareiro (octopus in olive oil), and fatias de carne frita à moda do Landal (Landal-style sliced fried meat). Attractions City Igreja de Nossa Senhora do Pópulo (Church of Our Lady of the Populace), adjacent to the thermal hospital, is a late gothic church with Mudéjar and Manueline characteristics. It serves as the mother church (igreja matriz) of Caldas. It was built 1500 by order of Queen Leonor and designed by Mateus Fernandes. The church was declared a national monument (monumento nacional) in 1910. Igreja de Nossa Senhora da Conceição (Church of Our Lady of the Conception) is a 20th-century church located on Praça 25 de Abril, near the city hall and the courthouse, and surrounded on three sides by Hemiciclo João Paulo II (John Paul II Semicircle). The Cardinal–Patriarch of Lisbon broke ground on 20 August 1950, and the church was inaugurated on 21 October 1951. Ermida de São Sebastião (Hermitage of Saint Sebastian) is a mannerist and baroque 16th-century chapel located just off Praça da República. An 18th-century reconstruction added tiles about depicting the life of the chapel's namesake saint. The chapel was declared a property of public interest (imóvel de interesse público, IIP) in 1984. Ermida do Espírito Santo (Hermitage of the Holy Spirit) is a mannerist and baroque chapel located on Largo João de Deus, uphill from the thermal hospital. Originally built in the 16th century, the hermitage was rebuilt in the 18th century. The chapel was declared a property of public interest in 1984. Praça da República (Republic Square) is a public square in the centre of town. The plaza, popularly known as Praça da Fruta (Fruit Square), hosts Portugal's only daily

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.
