OG-35：
By 1940, the pilot Jacqueline Cochran held seventeen official national and international speed records, and she earned them at a time when aviation was still so new for many of the planes she flew to be of dangerously experimental design.

A and she earned them at a time when avation was still so new for many of the planes she flew to be
B earning them at a time that aviation was still so new for many of the planes she flew were
C earning these at a time where aviation was still so new that many of the planes she flew were
D earned at a time in which aviation was still so new such that many of the planes she flew were
E earned at a time when aviation was still so new that many of the planes she flew were

OG-41
In 1850 Lucretia Mott published her Discourse on Women, arguing in a treatise for women to have equal political and legal rights and for changes in the married women’s property laws.

A.        arguing in a treatise for women to have equal political and legal rights
B.        arguing in a treatise for equal political and legal rights for women
C.        a treatise that advocates women’s equal political and legal rights
D.        a treatise advocating women’s equal political and legal rights
E.        a treatise that argued for equal political and legal rights for women

35题中的B,C 选项，OG 给出的解释为 earning就近修饰speed records，所以应该使用earned
41题中的AB 选项，OG 又说arguing的主语是Lucretia Mott （.. and it is redundant and confusing to present her as bothing publishing her Discourse and arguing in a treatise)

但是感觉主句的结构都是一样的啊， 都是谁做了什么，那为什么后面的V-ing修饰的主语就不同了？ 谢谢各位NN指导！！
