59. 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.

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

答案是A , 不明白为什么，请教详解，谢谢先！

honors degree的颁发率由20年前的10%提高到现在50%————》乱给高分导致文凭缩水了，雇主不像以前那么看重honors degree了。所以学校应该控制乱给高分，从而提高文凭的质量。

assumption: 现在的学生并不比以前的厉害。这样就去除了另外的导致高分的可能性

恩，排除它因。解不了题的根源还是在于没读懂原文的line of reasoning，绕进去了，哎。。。

谢谢LZ回复.

这样的思路的确是GMAT的思路，但是我觉得这题其实有问题。雇主并不看重的honors的原因是现在颁得太多了（50％），但是他要招的人一定是要在当时top10%的，这样的话，其实当代学生是否比20年前更厉害，其实是无关的吧。只有当雇主在招人的时候，只以honor为标准，那么学校为了增加honor的含金量，也就是说筛选出top10％，才需要把award的标准提高。

谢谢,明白为什么a对了。

我当时选的b（颁发太多degrees导致grade inflation）。再看看最后一句话：为了使颁发的degree值钱，就要控制grade inflation. 所以应当是grade inflation导致degree不值钱。所以b错。

如果不该这样分析，请指正。

To uibewsj 这种assumption的题还是向lawyer说的用取反然后能weaken原文的

就是选项（用来检查也是很好的） b取反显然不能weaken

一点拙见，大家探讨

这里其实并不是他因排除的假设，因为在结论里（to restore confidence in the degrees they award, colleges must take steps to control grade inflation）根本就没有因果关系，这样，何来他因排除？

偶以为，这题应该还是典型的assumption做法：搭桥法。文中的envidence是：twenty years ago no more than 10 percent of a given class graduated with honors；而conclusion是：... take steps to control grade inflation (grade inflation导致the hornors degree goes to more than 50 percent of a graduating class)；因此，我们需要搭桥的是在过去（20 years ago）和现今（today）之间建立桥梁关系，其实只有A是进行了这样的搭桥，所以A是正确答案
