You will be given a definition of a task first, then some input of the task.
This task involves creating questions from a given passage that involve some kind of complex reasoning (including numerical reasoning).
The generated questions must require looking at more than one part of the passage to answer. Try to use a variety of reasoning types in your questions (some of the sample reasoning types are illustrated in the 'positive examples' field) and also have a variety of answer types (spans, numbers, dates). A span is a continuous phrase taken directly from the passage or question. In such questions, the answer spans are recommended to be five words. Questions with answer type "number", are expected to start with "How many". For instance, "How long did an event last?" can be phrased as "How many years did an event last?". To increase diversity, try to create more questions for which the answer will be multiple spans. Please create questions that require AT LEAST 2 arithmetic operations as illustrated in the 'positive examples' field. You are encouraged to try DIFFERENT COMBINATIONS of operations and not just limit to the combinations shown in those examples. The more challenging questions you create, the better it is.

Passage: In 1993, Porsche Motorsports at Weissach briefly produced a Turbocharger 968 Turbo S, a fairly odd naming choice for Porsche which usually reserves the added "S" moniker for models that have been tuned for more power over a "lesser" counterpart, such as with the 911 Turbo. The 968 Turbo S shared the same body and interior as the Club Sport and visually can be identified by the NACA bonnet hood scoops, adjustable rear wing and deeper front spoiler. Powered by a large 8 valve SOHC cylinder head (944 Turbo S) with a 3.0 L 944S2 style engine block. Tests conducted in 1993 produced a 0 to time of 4.7 seconds and a top speed of , performance comparable to the much newer Porsche 996 911. It generated at 5,600 rpm with a maximum torque of at 3,000 rpm. Only 16 were produced in total and only for sale in mainland Europe.
Output:
How many Porsche model 968 Turbo S were made?
