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>
Jörg Berger Jörg Berger (13 October 1944 – 23 June 2010) was a German football manager and player, who last managed Arminia Bielefeld. Career As an active he played for 1.FC Lok Leipzig. Coaching career In 1970, Berger was forced to retire due to a muscle injury and started his managing career after the studying at the DHfK Leipzig. Berger was a reputable manager in East Germany who was planned to manage the East Germany national football team as successor of longtime manager Georg Buschner some day. Berger managed the youth team of the GDR. In 1979, he used a match in Yugoslavia to flee to West Germany. He signed with Second Bundesliga side SV Darmstadt 98. As a GDR refugee he suffered many threats by the East German secret police Stasi. He survived being poisoned whilst managing KSV Hessen Kassel in the mid-1980s. Evidence of the threats to his life were not available until 1990 when Germany was reunified, after which he was able to search his Stasi files. He was renowned as a great motivator, helping clubs threatened with relegation, but with little chance to build up teams over a longer period. Berger became the ’’fireman’’ of the Bundesliga after he twice failed to gain promotion to the Bundesliga with KSV Hessen Kassel, ending up in fourth position in the Second division of the Bundesliga (1984 and 1985). His greatest achievements were two third positions with Eintracht Frankfurt in 1990 and with FC Schalke 04 in 1996. He was replaced as manager of Schalke by Huub Stevens in October 1996 shortly before they won the UEFA Cup in 1997. Berger's last big success was reaching the DFB-Pokal final with Alemannia Aachen, a side from the Second division of the Bundesliga. However his contract was cancelled, by mutual agreement, after they lost to the then current champions (SV Werder Bremen) and failed to gain promotion to the Bundesliga. From 17 November 2004 until 14 August 2005, he was the manager of FC Hansa Rostock. He was fired after a 1–4 defeat by TSV 1860 München. On 18 May 2009, was named as the new Head Coach from DSC Arminia Bielefeld. His contract ran until 30 June 2009. He left the club on this date. Personal life Berger was the father of three children. In 2002, he had to interrupt his time as Alemannia Aachen manager due to an operation on an intestinal tumour. In 2005, he was operated on again, this time on liver metastasis. He released his biography "Meine zwei Halbzeiten: Ein Leben in Ost und West" (English: My Two Halves: A Life in the East and in the West) over the Leipzig based Rowohlt Verlag in March 2009. Berger died on 23 June 2010 of an enteric tumor.

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.
