不明白啊这2题...太晕了脑子...

Research has shown that when speaking, individuals who have been blind from birth and have
thus never seen anyone gesture nonetheless make hand motions just as
frequently and in the same way as sighted people do, and that they will gesture even when conversing with another blind person.

 
(A)
have thus never seen anyone gesture nonetheless make hand motions just
as frequently and in the same way as sighted people do, and that

(B)
have thus never seen anyone gesture but nonetheless make hand motions
just as frequently and in the same way that sighted people do, and  (but 重复，as frequent as, in the same way as， 根据句意第三个 and 要与第一个that平行）

(C)
have thus never seen anyone gesture, that they nonetheless make hand
motions just as frequently and in the same way as sighted people do, and (that they前面是一个名词加定于从句修饰没有谓语，make得主语使individual， 根据句意第三个 and 要与第一个that平行）
            

(D)
thus they have never seen anyone gesture, but nonetheless they make
hand motions just as frequently and in the same way that sighted people
do, and that  （thus 后的结构仍然是在定于从句中，不需要they作主语，其他错误与A B同）

(E)
thus they have never seen anyone gesture nonetheless make hand motions
just as frequently and in the same way that sighted people do, and

(B) while at the same time introducing some 100,000 dangerous chemical pollutants that have （主局和从句主谓一致的时候，再while,as等引导的从句中，主语可以省，谓语用现在分词代替，表示同时发生的动作，that  从句紧跟修饰对象）

(C) while they have introduced some 100,000 dangerous chemical pollutants at the same time, which have （which指代不明确， 在这里修饰time)

(D) but introducing some 100,000 dangerous chemical pollutants at the same time that have ( that 在这里修饰time, but没有while地功能，后面一定要跟完整的句子或对等的结构)

(E) but at the same time introducing some 100,000 dangerous chemical pollutants, having
