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>
Marek Janowski Marek Janowski (born 18 February 1939 in Warsaw) is a Polish-born German conductor. Janowski grew up in Wuppertal near Cologne, after his mother traveled there at the start of World War II to be with her parents. His father disappeared in Poland during the war. Janowski has served as music director in Freiburg and at the Dortmund Opera conducting the Dortmunder Philharmoniker, the latter from 1973 to 1979. From 1983 to 1987 he was principal conductor of the Royal Liverpool Philharmonic Orchestra. He served as Kapellmeister of the Gürzenich Orchestra in Cologne, from 1986 to 1990. Earlier, in 1984, he became the music director of the Orchestre Philharmonique de Radio France (then called the Nouvel Orchestre Philharmonique) in Paris, a position he held until 2000. From 2000 to 2009, Janowski served as Principal Conductor of the Monte-Carlo Philharmonic Orchestra. He was also Principal Conductor of the Dresden Philharmonic from 2001 to 2004. From 2002 through 2016, Janowski was chief conductor of the Berlin Radio Symphony Orchestra, initially with a contract for life with the orchestra at the time. In the 2005/06 season, Janowski began his tenure as Artistic and Music Director of the Orchestre de la Suisse Romande (OSR), with an initial contract of five years. In September 2008, his contract with the OSR was extended to 2015. However, in January 2010, in a change to the September 2008 contract extension, Janowski and the OSR mutually agreed on the scheduled conclusion of his directorship of the OSR after the 2011-2012 season. Janowski had served as chief conductor of the Dresden Philharmonic from 2001 to 2003. In September 2018, the Dresden Philharmonic announced the re-appointment of Janowski as its chief conductor, effective with the 2019-2020 season, with an initial contract of 3 seasons. In the USA, beginning in 2005, Janowski served as one of the conductors in a "triumvirate" of conductor leadership with the Pittsburgh Symphony Orchestra (PSO), with Sir Andrew Davis and Yan Pascal Tortelier, providing artistic guidance for the orchestra in the absence of a single music director. This arrangement ended in 2008 after the accession of Manfred Honeck as the PSO's music director. Janowski now holds the Otto Klemperer Guest Conductor Chair with the PSO. He has recorded the four symphonies of Johannes Brahms with the PSO. Janowski has made a number of operatic recordings, including the first digital recording of the complete Ring Cycle of Richard Wagner between 1980 and 1983 for RCA, with the Staatskapelle Dresden. He and that orchestra had earlier made the first recordings of Die schweigsame Frau by Richard Strauss, in 1976 for EMI, and of Euryanthe by Carl Maria von Weber, in 1974 for EMI, with Jessye Norman and Nicolai Gedda singing the lead roles. Another operatic first recording was of Krzysztof Penderecki's The Devils of Loudun with the Hamburg State Opera, shortly after he led the world premiere of the work in 1969.

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.
