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>
in an all-cash offer to an American private equity and hedge fund North Street Capital, for €32 million (US$41 million). In January 2012, Swedish Automobile again offered Spyker cars up for sale, but this sale did not actually occur. Saab was eventually sold in June 2012 to a Chinese-Swedish investment group called National Electric Vehicle Sweden (NEVS). In August 2012, Spyker announced that Youngman Ltd. acquired a 29.9% stake in its parent company Spyker N.V. for €10 million (US$12.5 million). Spyker after Saab In March 2013, the B6 Venator was unveiled at the Geneva Motor Show, the B6 Venator was noted as Spyker's first concept car in nearly four years. On September 16, 2013, Spyker Cars' parent Spyker N.V. lost its listing on Euronext Amsterdam after failing to undergo a restructuring agreement. On November 5, 2014, the Dutch Court "Midden Nederland" ordered Spyker to leave, within seven days, the factory they rented and to pay 152.000 euro in overdue rent. The claim was made by Jacques Walch, the owner of the factory rented by Spyker. Despite this, CEO Victor Muller insisted the company would be able to pay its bills "in a matter of days." On 2 December 2014 Spyker NV was granted a moratorium of payment (financial restructuring) by the Dutch court "Midden Nederland". Spyker needed protection from creditors for its liquidity problems. Victor R. Muller, Spyker founder and chief executive, said "Over the past few years, Spyker has faced a number of serious difficulties and challenges resulting from, among others, the legacy of the F1 era and the acquisition of Saab Automobile AB,". On 18 December 2014 Spyker NV was declared bankrupt by the Dutch court "Midden Nederland". Victor R. Muller, Spyker's founder and chief executive, said "In 2000 our objective was to found a global sports car manufacturer, and we did just that. During this time we deployed several challenging activities. These have affected the company, and contributed to our decline,". Spyker appealed the bankruptcy declaration, and on 29 January 2015, the court reversed the declaration. This meant that Spyker NV was protected from creditors, while solving its financial difficulties. This allowed Muller to pursue plans to merge Spyker with an unnamed "US based manufacturer of high performance electric aircraft." This proposed merger partner was eventually discovered to be a company called Volta Volare. On May 13 of that year, Spyker NV closed a deal with the creditors. Spyker owed 44 million euro and agreed to pay 12.000 euro per creditor. The curator of Saab GB was the largest creditor; it claimed 24,9 million euro. Saab GB agreed to receive a payment of 61.000 euro. A following attempt by the Latvian bank Lizings to claim more money, was declined by the court. On July 29, 2015, Spyker exited moratorium of payment (restructuring), and resumed business operations. In March 2016, Spyker announced the production of a new model, the C8 Preliator, at the Geneva Motor Show. Models Produced Spyker C8 The C8 Spyder was the original base model with an Audi 4.2 litre V8 engine. Since the start of its production in 2000, twelve different variants have been sold. A long wheelbase version was presented at the 2008 Geneva Motor Show, called the C8 Aileron. A year later, a convertible version was presented. Horsepower ranges from 400 for the original C8 Spyder to 620 for the C8 Double 12S. The most recent model, the C8 Preliator, was officially announced at the 2016 Geneva Motor Show. Only 50 vehicles will be produced. The car has a 4.2l supercharged Audi V8 producing 525 hp, resulting in a 0–100 km/h time

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.
