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:

are another dominant product group with car batteries and wiring installations as the most important products. Also, the production of engine components, mostly cast, is very significant, along with forged and machined parts like camshafts, brake discs, valves and flywheels. Among these manufacturing companies are: Tigar Tyres, Leoni Wiring Systems Southeast, Yura Corporation, Cooper Tire & Rubber Company Serbia, Trayal Corporation and IGB Automotive. Active manufacturers BIK Bus industries Kragujevac (BIK), in collaboration with Belorussian truck and bus manufacturer MAZ, began production by the late 2000s of gas-powered buses named BIK-203 which are based on the platform of the MAZ-203 model. These buses have been delivered to several Serbian towns to be in use in public transportation companies. FAP In 1952 Fabrika automobila Priboj (FAP) was founded and a year later the first trucks were produced based on a licence from Saurer. First domestically designed vehicles where introduced in serial production by 1965. In 1970 a production, technical and financial cooperation contract was signed by FAP with Daimler-Benz. In 1978 FAP began its collaboration with the Military Technical Institute Belgrade and started developing and producing special military vehicles. Since the 2010-s, FAP has military oriented and heavily limited production. FCA Srbija In 2008, FIAT entered a joint venture (JV) with the Republic of Serbia, creating what would become known as FCA Srbija. The JV extensively renovated and remodeled the former headquarters facility and assembly plant of Zastava Automobiles, and now manufactures the Fiat 500L, with an annual capacity of 85,000 cars (as of 2016). Ikarbus Ikarbus is a bus manufacturer based in Belgrade. The company was first founded in 1923 as "Ikarus A.D." to manufacture aircraft. After World War II the company was nationalised and two other Serbian aircraft manufacturers, Rogožarski and Zmaj aircraft, were merged into Ikarus. However, during the 1950s most of the personal and infrastructure of the aircraft factory were relocated to SOKO, and since then Ikarus has focused completely on bus production, first under licence, originally with Saurer and MAN designs, and later with the company's own. In 1992 the company was privatized, but due to a name dispute with Hungarian bus manufacturer Ikarus Bus, it changed name to Ikarbus. Zastava TERVO Part of Zastava conglomerate company in Kragujevac, TERVO was formed on 1 September 2017 with all fixed and current assets of Zastava Trucks including most of its former employees. Produces terrain vehicles for military and civilian use and armored cabins and parts for military vehicles. Defunct manufacturers IDA-Opel IDA-Opel was a car manufacturer based in Kikinda which produced Opel models under license between 1977 and 1992. It produced 38,700 vehicles.

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.
