没搜到PP 69（即GWD-TN-24中Q7）的讨论

In human hearing, subtle differences in how the two ears hear a given sound help the listener determine the qualities of that sound.

A.      in how the two ears hear a given sound help the listener determine

B.       in the two ears hearing a given sound help the listener in determining

C.      in how a sound is heard by the two ears helps the listener determine

D.      between how the two ears hear a given sound helps the listener in determining

E.       between how a sound is heard by the two ears help the listener in determining

答案为A

请教为何不选择E，我做的时候先选出了between的两个选项，然后排除D选择了E，感觉是一开始方向就错了，弱弱地问NN们between和in 如何抉择？？

谢谢！

help somebody do sth

in+范围

between ...and...

我感觉between应该是两者之间，而how引导的名词性从句表达的不是两者的意思，逻辑意思上有误。这道题从主谓一致（differences 与help一致）和惯用（help A do B）下手容易一些，因为differences一般和between搭配常见一些，是一个迷惑选项。
