试题详情
题目：
Most household appliances use electricity only when in use. Many microwave ovens, however, have built-in clocks and so use some electricity even when they are not in use. The clocks each consume about 45 kilowatt-hours per year. Therefore, households whose microwave oven has no built-in clock use 45 kilowatt-hours per year less, on average, than do comparable households whose microwave oven is otherwise similar but has a built-in clock.
Which of the following is an assumption on which the argument depends?
选项:
A、Households that do not have a microwave oven use less energy per year, on average, than do households that have a microwave oven.
B、Microwave ovens with a built-in clock do not generally cost more to buy than microwave ovens without a built-in clock.
C、All households that have a microwave oven also have either a gas oven or a conventional electric oven.
D、Households whose microwave oven does not have a built-in clock are no more likely to have a separate electric clock plugged in than households whose microwave oven has one.
E、There are more households that have a microwave oven with a built-in clock than there are households that have a microwave oven without a built-in clock.
答案:
D
提问：
读完文章后感觉应该和两类微波炉的区别有关， 于是剩下B和D。 因为看到原文里边谈到了cost的问题， 觉得B更近， 全了B。 请老师指点为什么不对
