标题: 逻辑难题请教牛人

答案好想错了,我感觉明明是C啊,为什么是A?

Top college graduates are having more difficulty demonstrating their superiority to prospective employers than did the top students of twenty years ago when an honors degree was distinction enough. Today’s employers are less impressed with the honors degree. Twenty years ago no more than 10 percent of a given class graduated with honors. Today, however, because of grade inflation, the honors degree goes to more than 50 percent of a graduating class. Therefore, to restore confidence in the degrees they award, colleges must take steps to control grade inflation.

Which one of the following is an assumption that, if true, would support the conclusion in the passage?

(A) Today’s students are not higher achievers than the students of twenty years ago.

(B) Awarding too many honors degrees causes colleges to inflate grades.

(C) Today’s employers rely on honors ranking in making their hiring decisions.

(D) It is not easy for students with low grades to obtain jobs.A

(E) Colleges must make employers aware of the criteria used to determine who receives an honors degree.

首先根据做假设题的原理,优先关注带有否定词的选择.恰好A.

那就看看A的内容,我们对A进行取反.

可以取成当今的学生要比20年前的学生水平高.

那么这肯定是对结论的削弱.因为当今学生水平高的话就不存在grade inflation的问题.结论提出的政策也就没有了意义....

allfar的方法很对   基本上现在看到assumption的题  就把选项取反  试试  当有一个是weaken的时候  答案就出来了
