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
C men and women需要用themselves指代
D of whom表述不佳
E 同C

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
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
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
himself和herself不对，前面是复数
时态和语态也不对，句意是要表达：以前被认为没有能力辨别真相的人登录 或 注册 后可以参加讨论
在本题的语境中，定语从句的表达比分词短语更清晰。分词短语既可做定语，又可表伴随。本题中，如果做定语，则时态错误，应该用过去(opened up)的过去(previsouly considered)，即过去完成时。若表伴随，having给伴随带了时效性，从时态上看也是错的，且伴随在这里的表达也不对。
who 前面不用加逗号的吗
