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 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. 答案是D 其餘答案我都可以排除錯誤但我想知道 D取非有反駁嗎??? 謝謝 -- (1)問題____ (A)孬(B)奀(C)尖(D)奔 (2) 不離不棄被當____ (A)盲(B) 臬(C)皂(D)柏 (3) 時機若對我第一個 ___ (A)加入工會(B)加入大聯盟(C)退休(D)打入WWE (4)╰(‵◇ ′#)╯代表哪個單字(A)good job (b)Come on (c)fuck u (d) shit (5) 監督賞可拿到多少賞金(A)3萬鎂(B)一萬鎂(C)2千NT(D)一萬NT -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 67.171.108.168
