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>
Museum Boijmans Van Beuningen Museum Boijmans Van Beuningen () is an art museum in Rotterdam in the Netherlands. It is located at the Museumpark in the district Rotterdam Centrum, close to the Kunsthal and the Natural History Museum. The museum opened in 1849. It houses the collections of Frans Jacob Otto Boijmans (1767–1847) and Daniël George van Beuningen (1877–1955). In the collection, ranging from medieval to contemporary art, are works of Rembrandt, Claude Monet, Vincent van Gogh, and Salvador Dalí. In 2013, the museum had 292,711 visitors and was the 14th most visited museum in the Netherlands. History The museum was established in 1849 as Museum Boymans with the collection of Frans Jacob Otto Boijmans (1767–1847). The painter and art dealer, Arie Johannes Lamme, was named the museum's first Director. Much of the museum's original collection was destroyed in a fire in 1864. The collection of businessman Daniël George van Beuningen (1877–1955) was added in 1958, at which point the museum acquired the name Museum Boymans-van Beuningen. The spelling was changed to Museum Boijmans Van Beuningen in 1996. Collection The museum has a diverse collection ranging from medieval to contemporary art, with somewhat of a focus on Dutch art. Much of the collection came to the museum through the two private collections mentioned above, but many others have contributed throughout the years. Among the best-known artists that are exhibited in the permanent exhibition of the museum are Hieronymus Bosch, Pieter Bruegel the Elder, Rembrandt, Claude Monet, Wassily Kandinsky, Vincent van Gogh, Maurizio Cattelan, Paul Cézanne, René Magritte, Salvador Dalí, Mark Rothko, Edvard Munch, Willem de Kooning, and Yayoi Kusama. The collection also includes one of the richest assembly of works on paper (etchings, drawings, lithographs, etc.) in the world from the Middle Ages to the present times. Selected works The Glorification of the Virgin (c. 1490–95) by Geertgen tot Sint Jans The Wayfarer () by Hieronymus Bosch Nest of Owls () by Hieronymus Bosch The "Little" Tower of Babel () by Pieter Bruegel the Elder Titus at his Desk (1655) by Rembrandt Hut of the Douaniers with Varengeville (1882) Claude Monet Portrait of Armand Roulin (1888) by Vincent van Gogh On the Threshold of Liberty (1929) by René Magritte Not to be Reproduced (1937) René Magritte Impressions of Africa (1938) Salvador Dalí Shirley Temple, The Youngest, Most Sacred Monster of the Cinema in Her Time (1939) Salvador Dalí The Face of War (1940) Salvador Dalí Activities The Education Department of the Museum organises children's activities, courses, lectures and tours. ARTtube ARTtube is a website with videos about art and design. ARTtube is produced by Museum Boijmans Van Beuningen, M HKA Antwerp, Gemeentemuseum Den Haag, Stedelijk Museum Amsterdam, De Pont, Centraal Museum Utrecht, Museum Jan Cunen and Rotterdam. Television Museum Boijmans Van Beuningen produces, together with TV Rijnmond, a television series on art. Boijmans TV is based on an idea by Wilfried de Jong. Boijmans TV is created by a team of creative specialists in different disciplines. It is more than an art magazine; apart from the artists, the museum visitor, the attendant and the employee of technical services appear on the series. Each episode of Boijmans TV can be viewed on ArtTube after it has been broadcast. Administration Sjarel Ex has been the museum director since 2004. The museum had 292,711 visitors in 2013. That year it was the most visited museum in Rotterdam and the 14th most visited museum in the Netherlands. It had an estimated 270,000 visitors in 2015.

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.
