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>
task became to secure storage for the museum's collections, which were found in the salt mines of the Salzkammergut. After the war, American officials transferred all the Salzkammergut art objects to Munich, mixing the stolen German objects with the meticulously cataloged Austrian ones, so Spitzmüller was required to go there to sort through them. On March 13, 1945, an Allied bomb struck the Albertina. Spitzmüller recalls that she and her colleagues were repairing the resulting hole in the museum's roof on the day Perry Blythe Cott (one of the "Monuments Men") visited them. With Cott, she went to Munich to retrieve the paintings and graphic art that had been stored before the war; she was able to see many of the Jewish artworks confiscated by the Nazis. During the war, she had met Otto Benesch's family, and through his father, Heinrich Benesch, an important art dealer and friend of Egon Schiele, had secured for the Albertina the Roessler collection of Schiele’s graphic art. After the war, she spent much time in Vienna's French zone, organizing exhibitions and finally travelling to France to reestablish art contacts there. In 1946, she mounted a cooperative exhibition with the French, highlighting artworks in the Albertina's holdings. Her catalogue of the show, Französische Phantastik, was one of the first art publications produced in Vienna after the war. Later life In 1948, Spitzmüller was appointed to the highest level of Curator in the governmental rankings, and remained at the Albertina until 1954. During this time, she worked on some of the first "little guides" to the Albertina’s collections, part of her ongoing efforts to make the collections more accessible. In 1953, she traveled to the United States to study graphic collections there; she once again saw Cott, and became lifelong friends with Agnes Mongan, curator of drawings at Harvard's Fogg Art Museum. Returning to Vienna, she left the Albertina to move to the Kunsthistorisches Museum, where she worked to make the museum more accessible to the public, to encourage school visits, and to sponsor symposiums and lecture series; she also was a founding member of the Austrian chapter of Zonta International. When she reached mandatory retirement age in 1969, she was given the title of Hofrat and made an honorary member of the Österreichischen Kunsthistorikerband; she also received the Chevalier ribbon of France's Ordre des Arts et des Lettres. In that same year, she gave a talk at the Library of Congress in Washington, D.C., on Bruegel's paintings. In retirement, Spitzmüller continued teaching groups of American students through the Austro-American Institute of Education, which she had done since the 1930s (except during the war). In particular, she established a relationship with Hope College in Michigan, which brought groups of students to Vienna for summer school. In 1987, Hope College honored her in conjunction with an exhibition of Viennese art at the school. Spitzmüller was also a talented musician, and participated in many activities involving the Vienna Philharmonic. In 1993, the Albertina, as part of a video history of the institution, interviewed her with special focus on her time there. She died September 25, 2001, at the Heim der Kaufmannschaft in Vienna.

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.
