请教下 OG13 SC 35,对比了以下DUKB和OG的解释感觉有点不懂

题目OG35：

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

这里主要是有两个点不懂
1.earned和earning可以互换么？ OG说Ving和Ved是指代人和物的不同，DUKB的解释中说可以替换为Ving形式帖子，链接（http://forum.chasedream.com/thread-761205-1-1.html），从mahattan讲解的知识点（mahattan的SC的P90）来看的话，这个两句既没有因果关系，又没有同时发生，所以不用comma+Ving而用comma+Ved来修饰。

2.OG说D选项的the correct pronoun for time is when。但是mahattan上面说的都可以用（SC专册P79，下面有附图啦）


以上就是我的问题，怎么也没想明白，求大牛赐教

可以互换啊。做的多了，你会发现ving，ved都能修饰前面的名词，不那么care，这个时候你的关注点不应该是到底用ving还是ved，而是后面的成分。
when一般跟在time后面，in which也可以但是不如when更符合“习惯”罢了。
你问这些都不算绝对考点，只能这样，相对的比下去。就是说有些东西不是不行，是在这里不如别的好。

好的，谢牛牛，我刚才看了一下，每个选项的确除了这个点还有其他的问题，是我舍本逐末了，嘿嘿

所以B的错误不在earning，而在the time后面本来应该用when，但它用了that？
