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>
one of his trips, he met with the aging German sculptor Gerhard Marcks, who had been Wildenhain’s form master at the Bauhaus, and, in another, he and Geraldine Schwarz interviewed British potter Bernard Leach. These experiences, not unlike his earlier quest to visit the studios of famous potters, reflect his continuing interest in historical sleuthing, especially as it relates, non-exclusively, to the tradition of ceramic art. Related to those inclinations, he and/or Geraldine Schwarz (often in collaboration with others) have written, compiled and sometimes published books having to do with historic issues, both local and international. Among these, for example, are Conversations with the Recent Past (Luther College Press, 1975), a collection of oral history interviews with rural residents in the vicinity of Decorah, Iowa; and Paddled Tails from Tattled Tales: An Autobiography of a Family (South Bear Press, 2001), consisting of archival photographs and oral history interviews of their own family members. South Bear Press In the late 1970s, the Schwarz family launched a small book company called South Bear Press, the first consequence of which was the publication of the third and final book authored by Marguerite Wildenhain, titled …That We Look and See: An Admirer Looks at the Indians, edited by John Nellermoe and Dean Schwarz (South Bear Press, 1979). In 2004, nearly twenty years after Wildenhain’s death, they produced a second volume pertaining to her life, titled Marguerite A Diary to Franz Wildenhain, edited by Dean Schwarz, consisting of her diary-like letters (never posted) to her husband, Bauhaus potter Franz Wildenhain, during their wartime separation in 1940, when his whereabouts were unknown. More recently, in 2007, after more than a decade of research in Europe, UK and the US, Dean and Geraldine Schwarz compiled and edited a large format, 770-page anthology on the history and legacy of the German pottery tradition, titled Marguerite Wildenhain and the Bauhaus: An Eyewitness Anthology (South Bear Press). In this volume are essays, memoirs, diaries, letters, interviews and other written documents by or about such Bauhaus- or crafts-related persons as Josef Albers, Ruth Asawa, Theodor Bogler, Lyonel Feininger, Walter Gropius, Trude Guermonprez, Shoji Hamada, Bernard Leach, Otto Lindig, Gerhard Marcks, Daniel Rhodes, Peter Voulkos and Frans Wildenhain. In 2009, coincident with the 90th anniversary of the founding of the Bauhaus, Dean and Geraldine Schwarz published an essay in book form titled Centering Bauhaus Clay: A Potter's Perspective (South Bear Press).

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.
