Most drivers drive fewer than 30,000 miles per year. Some drivers also purchase car insurance or pay for oil changes every 5,000 miles. A few drivers have a car accident each year. If a driver drives less than 30,000 miles per year, they receive a discount on their car insurance. All drivers must be licensed by one or more states.
If the preceding passage is true, then which of the following MUST be true?
Explanation
Answer: C - A few drivers receive a discount on car insurance every year. The question asks what MUST be true, not what could be true. Answers A, B, D, and E all could be true, but do not have to be. Answer A does not have to be true, because it is not stated that each person purchasing car insurance is also paying for an oil change; some drivers may only do one or the other. Answer B need not be true because only some, not necessarily most, drivers pay for car insurance. Answer D is incorrect because those drivers who pay for an oil change every 5,000 miles are not necessarily the same as those who drive less than 30,000 miles. Answer E is also incorrect because while all drivers must be licensed, only some drive less than 30,000 miles or purchase car insurance. C is the only answer that MUST be true. Most drivers drive fewer than 30,000 miles per year, and these drivers receive a discount. Thus, at least a few drivers are receiving a discount on car insurance every year.
