Question

Quizplus · Accepted Answer

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.
