35. By 1940, the pilot Jacqueline Cochran heldseventeen official national and international speed records, and she earnedthem at a time when aviation was still so new for many of the planes she flewto be of dangerously experimental design.
(A) and she earned them at a time when aviation wasstill so new for many of the planes she flew to be
(B) earning them at a time that aviation was still sonew for many of the planes she flew to be
(C) earning these at a time where aviation was stillso new that many of the planes she flew were
(D) earned at a time in which aviation was still sonew such that many of the planes she flew were
(E) earned at a time when aviation was still so newthat many of the planes she flew were
我就是想问一下，BC两个选项，抛开其他错误不谈，光看前面的earning......这个结构，如果说是做伴随状语修饰主句可不可以？
因为OG的解释是，earning不能修饰records，就默认了这个ing结构是做定语的了，理解为做状语不行吗？
