GWD 24-8

[Karen]

24-18 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.


Ans: D

請問 最後一句的句意為何? (On average, than do comparable households whose microwave oven is otherwise similar but has a built-in clock.)

hi KAREN : 醬清楚了吧 ^^

不要生氣 ets 要阻擾聰明的台灣人考太高

總要耍點陰險的手段咩 ;)

我覺得應該是作者打字打錯耶[on average]應該是插入句

另外想請教一下,為何D是原題的假設呀?
看完原題,我覺得假設應該是[擁有有無內建clock微波爐的家庭,每年使用量差不多之類的]在這樣基礎下比較
看不出來D為什麼對耶
煩請各位高手指點一下囉

哦哦...難怪看不懂最後一句是什麼意思...
我也覺得好像是作者打錯了！

這題我也思考了好久！
我覺得這題的第一句話是重點
Most household appliances use electricity only when in use.
許多家電用品用電當他們使用時。

D選項說
微波爐沒有內建clock的家庭，也不可能會再放一個要另外接電的clock，相較於本來有內建的。

因為第一句說...when in use
而D就是假設前提囉！
因為本來就沒內建了！表示當初就認為沒有使用的必要，於是也不會想再另外接clock，而剛好符合題目的first sentence
其他後面，都只是要影響思考的廢話。

有錯請指正 謝謝

I agree with you !!!!

When you compare two different items, other things/variables for these two items have to be the same.

In this question, it compares microwaves with built in clock vs. without built in clock, so when we consider an answer, we have to choose the one which mentions that microwaves without built in clocks can't have other ways to install other kind of clocks; otherwise, the electric clocks will also consume electricity, and this makes the comparison not valid.
