OG13-35
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 aviation
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 to be
(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
答案是E。
我选的A，A哪里不对呢？ 本人语法极弱，求别拍，求解释xiexie

and是并列结构，但这个句子其实有点算是补充前面的句子，而不是交代一个新的东西，不知道这样解释对不对

我觉得，第一，这里用的是so....that结构，A选项中把that给省略了，不然应该放在she前面的。
其次，我就觉得to be of 这个句型挺奇怪的。一般to引导的不定式是表示目的吧，但是这里只是陈述一个事实，应该用符合原句时态的simple  past tense

skyemotion的回答：wordy的原因应该是增加了she，从句和主句主语一直时，从句主语需要省略。
后面的那个for可以理解成为连词，因为。我觉得很有道理。
