错选A，AB之间主要有个时态的差别，A也是做定语修饰men and women， 相比较B多了一层含义，就是时态，过去完成时。

aving done 结构肯定是做状语的修饰主句的动作的，不是定语来修饰名词的。如果你having done结构只是来修饰一个名词的，那何谈和名词的先后顺序的？ 那什么时候 现在分词doing 做定语呢？在GMAT中 如果 doing结构不加逗号直接放在名词后面，往往都是做定语的，所以我们可以推断出: having done 是永远不会做定语的。具体来说 也就是永远不会没有逗号而存在。
1. men and women，所以要用themselves，排除CE
2. D选项还原 it had previously been considered of men and women they were incapable of discerning truth for themselves ，首先引导从句省略了that，其次句意完全读不通，所以排除
3. having been done只能做状语

A having 作定语不当
C men and women需要用themselves指代
D of whom表述不佳
E 同C

himself or herself指代单数，men and women为复数

In order to act as an action modifier, the having modifier must be preceded by a comma. But there is none in the original sentence.

Choice A does not stand as a correct answer because the intention of the sentence is to show the sequencing of the events. But the having modifier now just presents the additional information about men and women. It is not really associated with the action opened up as such.

用动名词修饰名词，没有用定语从句好，现在完成时也不可以充当修饰成分

A选项：用动名词修饰名词，没有用定语从句好
C选项：himself or herself不能指代men or women
D选项：of whom多余，造成冗杂
E选项：问题同C

a, having been 修饰不对，现在完成时不可以充当修饰成分
c, himself or herself指代不对，主语是men and women, himself，herself只能用来指代单数
d,whom是宾格形式，所以从句没有主语
e，错误同c

ABDE

A有伴随嫌疑，B直接用定语从句更好

OG2017V-SC-211请问c错在哪里

为什么一定要用从句？A不正确？
