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>
Ritt Bjerregaard Ritt Bjerregaard (full name Jytte Ritt Bjerregaard, born 19 May 1941) is a former Danish politician. She is a member of the Danish Social Democrats, and was Lord Mayor of Copenhagen from 1 January 2006 to 2010. Bjerregaard was Education Minister from 27 September to 19 December and again from 13 February 1975 to 22 December 1978. 1973 and from 1975 to 1978 in the Cabinets of Anker Jørgensen I, II and III, and Social Minister from 1979 to 1981 in Anker Jørgensen's fourth cabinet. She was European Commissioner for the Environment from 1994 to 1999 and Minister for Food, Agriculture and Fisheries in the Cabinet of Poul Nyrup Rasmussen IV from 2000 to 2001. Political career She was a member of the Danish parliament (Folketinget) from 21 September 1971 to 22 January 1995 and from 20 November 2001 until 8 February 2005. She was a minister of various cabinets under Anker Jørgensen, and Poul Nyrup Rasmussen. In 1971 she was elected to the Odense City Council where she served just one term and resigned in 1973. In 1971 and 1975-1978 she held the position as minister of education, where she changed the Primary School Act in 1975 with the support from the majority of the other parties. On 5 November 1975 Bjerregaard hired an external chancellor for Roskilde University. Venstre and Conservative People's Party wanted to abolish the university, but thanks to the independent politician, former Conservative People's Party member Hans Jørgen Lembourn, the university was saved. In 1976 she introduced restricted admission at the universities meanwhile secured the protection of minorities. In 1977 Bjerregaard got the law about Erhvervsfaglige Grunduddannelser - EFG (Vocational basic training) approved. With former head of department Erik Ib Schmidt she launched the ambitious, complete education plan U 90 from 1978. After the fall of the Berlin Wall, Ritt changed her stance on EU. After being an opponent for many years, she became chairman The Danish European Movement (Den Danske Europabevægelse). Bjerregaard was the European Commissioner for Environment, Nuclear Safety and Civil Protection in the Santer Commission from 1995 to 1999, representing Denmark. She has attended at least one Bilderberg Group meeting on 8–11 June 1995. She has also attended Trilateral Commission meetings in 1992, 1998 and 2002. She has been involved with various organisations. She was vice-president of both OSCE's Parliamentary Assembly and Socialist International Women (SIW) from 1992 to 1994. Four days after Bjerregaard was appointed minister of food in February 2000, the first case of mad cow disease, a dangerous brain disease, occurred. With the ministry Bjerregaard acted fast and consistently. The butchering methods were changed and a ban on risk products was installed. These consistent measures were first not received well, neither by the farmers nor the food industry. Especially the initiative to withdraw certain foods from the retailers was criticised. But later on the industry realized that the measures protected the consumers and created great confidence in Danish food products at the export market. In 2001 Bjerregaard introduced the Smiley system. It made occasion for big discussions but today the system is generally recognized. Bjerregaard won the election for Lord Mayor of Copenhagen for the Social Democrats on 16 November 2005, a position she acquired through a high number of personal votes. During her time as Lord Mayor of Copenhagen, Ritt invited mayors of cities around the world to a summit about the climate in the cities. The summit was a prelude to COP15, which took place in Copenhagen. At the summit, Ritt Bjerregaard wished to discuss what the big cities could do to lower CO2-emissions. The

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.
