題目如下:

Each of the following,if true,weakens the argument above EXCEPT:

a)Europeans are more likely to wear safety belts than are people in the Unite States.

b)Unlike United States drivers,European drivers receive training in how best to react in the event of an accident to minimize injuries to themselves and to their passengers.

c)Cares built for the European market tend to have more study construction than do cars built for the United Statesmarket.

answer 請解惑

According to a 1980 survey,ten percent of all United States citizens over the age of sixteen are functionally illiterate.Therefore,if the projection that there will be 250 million United States citizens over sixteen in the year 2000 is correct,we project that 25 million of these citizen will be functionally illiterate.

which of following,if true,would most weaken the conclusion drawn by the author of the passage above?

答案是B

B)from 1975 to 1980 there was a three-percent decrease in the rate of functionally illiterate among United States citizens over the age of sixteen.

我在想為什麼答案說1975~1980文盲比率下降3%,這樣跟題目結論所要求的2000年不同也能夠有weaken效果嗎?

2000年說不定文盲率跟1980年代一樣,好像也不是不可能,即使在1975~1980年時曾降低3%過

請解惑

我觉得第一题的话ABCE都说明了safety belt不是造成美国有more severe injuries to passengers 的原因

而D它只说了美国从统计上看车祸率高，而车祸率高有很多原因，可能就是由于safety belt standard的原因，所以它不能weaken

第二题，因为你没给出别的选项，所以很难判断出一个“最好”的答案是什么
