题目分析：
本题很长，但是长度和难度是没有关系的。搞清楚题目中各个小句之间的关系方可解决这个问题。
选项分析：
A选项：Correct. 本选项在语法上和逻辑上均是正确的。
B选项：时态有误。make hand motions应该和sighted people do保证时态相同，且由于两者均表示一般性的真理，都应该用一般现在时。
C选项：时态问题同(B)；individuals gesture even when conversing with another blind person应该也是调查者发现的现象，因此应该和individuals make hand motions在语法上平行。
D选项：时态问题同(B)；平行问题同(C)。
E选项：本选项没有谓语动词。
那c的as well as gesturing 是对的吗？ as well as +doing 是一种用法，但是这里需要和made hand motion的时态平行吗？
D、E选项的“thus never having seen anyone gesture”的having seen有问题吗？这里的动词前面加一个have 是否可以理解成为先时性，在已经看不到任何人的手势的情况下，也会做手势？
可以。

B还有一个地方也有问题，就是 never saw， 用了过去式，莫名其妙
