HideShow timer Statistics

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?

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 separately 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.

My answer is D.

Author assume that households whose microwave oven has no built-in clock use less power because microwave is the only appliance used as a clock.

A. not important

B. out of scope

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 separately electric clock plugged in than households whose microwave oven has one.

E. not important

Between C and D, I go with D. D says that another electric clock is plugges in seperately, and if so, the difference would not be 45kwh per year but less.
