6.     James’s grade point average puts him in the top third of the graduating class of college A. Nestor is in the top tenth of the same class. Elizabeth had the same grade point average as Nestor. Nancy has a lower grade point average than Elizabeth.

请问highlight部分的表达同among the top three of 的表达意义是否一样？谢谢！

谢谢lawyer版主！不过这题是逻辑题，所以偶发在这里。

刚刚又看了一下原题，根据反证发，偶觉得这两种表达应该是一样的，请看题目：
6.     James’s grade point average puts him in the top third of the graduating class of college A. Nestor is in the top tenth of the same class. Elizabeth had the same grade point average as Nestor. Nancy has a lower grade point average than Elizabeth.

If the information above is true, which of the following must also be true?
(A) James has a higher grade point average than Elizabeth.
(B) James has a higher grade point average than Nancy.
(C) Nestor has a higher grade point average than Nancy.
(D) Elizabeth and Nancy both have a higher grade point average than James.（C）
(E) Nestor and James both have a higher grade point average than Nancy.

由正确答案是C，得出B选项是错误的。
1. 根据lawyer版主的理解in the top third是第三名，那么根据Nestor is in the top tenth of the same class，Nestor是同一班级里的第十名，推出James的成绩比Nestor高。James > Nestor.

2. 然后根据Elizabeth had the same grade point average as Nestor. Nancy has a lower grade point average than Elizabeth.推出Elizabeth的成绩同Nestor一样，且高于Nancy. Elizabeth = Nestor > Nancy.

结合1和2可以得出，James的成绩高于Nancy. (James > Nancy)即B选项。

因为B选项不是正确答案，所以原理解前提是错误的。

谢谢lawyer，激发换个角度看问题的灵感。
