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>
Kunsthalle Mannheim The Kunsthalle Mannheim is a museum of modern and contemporary art, build in 1907, established in 1909 and located in Mannheim, Germany. Since then it has housed the city's art collections as well as temporary exhibitions - and up to 1927 those of the local Mannheimer Kunstverein as well as its administration. Collection The Kunsthalle’s own collection comprises around 1,500 works by artists including Édouard Manet, Paul Cézanne, George Grosz and Wassily Kandinsky. The extension building from 2018 shows a major collection of works by Anselm Kiefer, 38 pieces on long-term loan from the businessman Hans Grothe. Architecture Designed by Hermann Billing, the building was erected as a temporary structure to serve an "International Art Exhibition" of 1907, commemorating the 300th anniversary of the foundation of the city. Originally meant to be torn down after this exhibition, the building was later transformed into a municipal art gallery. In 1909 the museum and the collection were opened under the first director Fritz Wichert. In 1983 Heinz Fuchs, Director of the Kunsthalle from 1959, handed over an extension building, designed especially for the sculpture collection by architect Hans Mitzlaff, to his successor Manfred Fath. A new building, in size with seven exhibition halls and a 22m-high glass-roofed atrium designed by the Hamburg-based architects Gerkan, Marg and Partners opened in 2018. The concrete, glass and steel structure is enveloped in a bronze mesh. Directors of Kunsthalle Mannheim 1909-1923 Fritz Wichert 1923-1923 Gustav Friedrich Hartlaub 1933-1959 Walter Passarge 1959-1983 Heinz Fuchs 1984-2002 Manfred Fath 2002-2007 Rolf Lauter 2008-2019 Ulrike Lorenz Since 2019 Johan Holten Fritz Wichert (1909-1923) Fritz Wichert, who completed his doctorate in 1907 in Freiburg, became director of the Kunsthalle in Mannheim as early as 1909, where he expanded the collection to include paintings from the 19th century with a focus on French Modernism. In the First World War Wichert belonged to the diplomatic service. After the war, he returned to the Mannheim Kunsthalle and now put the collection focus on the Expressionists. In 1923, Wichert was appointed as director of the Städelschule in Frankfurt. Gustav Friedrich Hartlaub (1923-1923) Fritz Wichert brought Hartlaub 1913 as an employee to the Kunsthalle Mannheim. In 1923 he became its director. He was particularly committed to promoting contemporary art and expressionism. With the exhibition "Neue Sachlichkeit - Deutsche Malerei seit dem Expressionismus” (New Objectivity - German Painting since Expressionism), which opened on June 14, 1925, he coined the term New Objectivity. On March 20, 1933, he was dismissed in the course of National Socialist cultural policy. Walter Passarge (1933-1959) From July 1, 1936 until his death Passarge was director of the Kunsthalle Mannheim. From 1937 until 1945 he dealt mainly with the second wave of seizures by the National Socialists and he saw himself exposed to the "purification of the museums of degenerate art." At that time he shifted the focus of the Kunsthalle on the politically less tangible arts and crafts. After World War II, it was up to him to rebuild the Kunsthalle's holdings, which had been severely curtailed by the effects of National Socialism and the World War, paying special attention to German and modern art as well as the collections of the 19th and 20th centuries. Only from 1949 parts of the collection could be shown again after the repair of the heavily damaged main building. Heinz Fuchs (1959-1983) Fuchs received his doctorate in art history in 1939 and worked as a curator since 1947 at the Kunsthalle Mannheim under the director Walter Passarge. From 1959 to 1984 he was director of the Kunsthalle. During this time he was able

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.
