Given the task definition and input, reply with output. 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: While the 1981 season gave Petty 3 wins, he felt the season was a failure, and the Regals being ill-handling and poor in reliability. For 1982, he made the move to the Pontiac Grand Prix, with the promise of substantial factory support from Pontiac. 1982 was a repeat of 1978, and no victories were to be had. At first, the Grand Prix behaved much like the Dodge Magnum of 1978, with handling and speed problems. Toward the end of 1982 things improved with several top-10 finishes, which opened the door to a successful 1983 season with three victories, and several top-5 and top-10 finishes. In 1983, he broke his 43-race winless streak from 1982 with a win in the 1983 Carolina 500, barely edging out a young Bill Elliott. After a controversial win at Charlotte, North Carolina in October 1983 (win No. 198), Petty left the race team his father founded for the 1984 season. He spent 84 and 85 driving for Mike Curb before returning to Petty Enterprises in 1986.
How many years did he drive for Mike Curb?
