标题: 请教一道大全逻辑题,困惑。。

18.   It’s time we stopped searching for new statistics to suggest that we are not spending enough on education. In fact, education spending increased 30 percent overall during the last decade.

Which of the following, if true, would most weaken the argument above?

(A) Despite increased spending on education, enrollment in our elementary and secondary schools declined about 4 percent during the last ten years.

(B) Our spending on gasoline increased more than 100 percent during the last decade.

(C) When adjusted for inflation, our per-pupil expenditure on education this year is less than it was ten years ago.

(D) Eleven other economically developed nations spend more on education than we do.C

(E) The achievement levels of our students have been declining steadily since 1960, and the last decade produced no reversal in this trend

题意说:不用再去寻找数据反驳我们在教育上的花费。事实上,我们的花费已经增长了30%。

逻辑就是花费增长了,那么就说明我们已经spend eough on education( 不知道对不对?)

 

不明白为什么是答案C

MM的逻辑没有错。
但是,花费真的增长了吗?可以统计花费总量,也可以统计平均个人花费。由于通货膨胀的抵消作用,平均个人花费没有增长反而更低了。这怎么能说明spending on education is enough呢?所以C是最佳答案。

就是C啊。首先是说增长了。 但是他说的增长是绝对数目的增长。 相对于比如通货膨胀,这个增长可能就可以忽略甚至还不如以前高。 你可以想想物价,如果不理解。

MM的意思是他因削弱,考虑了通货膨胀,举了一个通货膨胀的事实来削弱结论。

一开始没有看出来

明白了。谢谢
