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>
Anna Spitzmüller Anna Spitzmüller (September 6, 1903 – September 25, 2001) was an Austrian art historian, curator, and educator. She taught art history to generations of American college students through the Austro-American Institute of Education, and was the first woman curator in Vienna. Early life Spitzmüller was born September 6, 1903, in the Moravian town of Znaim (now Znojmo, Czech Republic), the daughter of an old Austro-Hungarian military family. Her mother also came from an aristocratic background, and her ancestral home still stands in Znojmo. Her father was Amadeo Spitzmüller von Tonalwehr (18711945), a high-ranking Imperial Army officer, and her "beloved uncle" was Alexander Spitzmüller, Freiherr von und zu Spitzmüller-Harmersbach (18621953), a well-known economist and banker who was the last imperial finance minister for the Austro-Hungarian Empire. Her grandfather originally came from Bukovina, one of the furthest regions of Austro-Hungary. She spent her earliest years in Prague, then a time in Olmütz. She learned to speak Czech among other languages. Her father was then stationed permanently at the War Ministry in Vienna, where she remained for the rest of her life. She later described her upbringing as "completely free and open", with an active social life among Austria's cultural elite. Dinner conversations were learned and scholarly; her father was very educated, and her mother was very musical. She was privately tutored as a girl, and learned French and English from governesses. She then attended the Rahlgasse Mädchengymnasium, the first academic school for girls in Vienna. In 1920, impressed by an exhibition of tapestries at the Belvedere, she decided she wanted to be an art historian. In 1921, she enrolled at the University of Vienna to study with Josef Stryzgowski, controversial antagonist of the so-called Vienna School of Art History led by Max Dvořák and Julius von Schlosser. She received her degree in 1926 with her dissertation Die Brüder Strudel als Plastiker. Ein Beitrag zur Geschichte der Hofkunst Kaiser Leopold I ("The Strudel brothers as sculptors: A Contribution to the History of the Court Art of Emperor Leopold I"; Paul Strudel and Peter Strudel were the late 17th-century sculptors who created the oldest artists' academy in Central Europe). Career Her first project after finishing her degree was an inventory of the major monuments of Carinthia, the southernmost province of present-day Austria, for the Dehio Handbuch der deutschen Kunstdenkmäler Österreichs. Lack of transportation meant she completed the inventory on foot. Returning to Vienna in the fall of 1926, Spitzmüller went to the office of Otto Benesch, curator at the Albertina, and (according to her own account) announced Gruss Gott, ich möchte hier arbeiten! ("Hello, I would like to work here!"). Benesch made her the first woman curator in Vienna. Spitzmüller worked under the Albertina's director (18821957), in one position or another, for the rest of her career. With Stix, she prepared the complete catalogue of the Albertina's drawings (Beschreibender Katalog der Handzeichnungen in der graphischen Sammlung Albertina); she was especially responsible for volume 6, Die Schulen von Ferrara, Bologna, Parma u. Modena, d. Lombardei, Genuas, Neapels u. Siziliens, on the collection's Italian works. When Stix was appointed to the Kunsthistorisches Museum in 1934, Spitzmüller's position at the Albertina became more important. Nazi period With the Nazi takeover of Austria, Stix and Benesch lost their positions. Stix stayed in Vienna and worked, apparently surreptitiously, with Spitzmüller in the Albertina collections. Nazi directors were appointed at all the Viennese museums, but according to Spitzmüller, they were figureheads who had little impact on the running of the institutions. "We continued our research, but couldn’t publish anything", she recalled. As war became imminent, her most important

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.
