答案一定错了！

In astronomy the term “red shift” denotes the extent to which light from a distant galaxy has been shifted toward the red, or long-wave, end of the light spectrum by the rapid motion of the galaxy away from the Earth.
(A) to which light from a distant galaxy has been shifted
(B) to which light from a distant galaxy has shifted
(C) that light from a distant galaxy has been shifted
(D) of light from a distant galaxy shifting
(E) of the shift of light from a distant galaxy

答案给了A，我觉得肯定是D和E之间的~
我选了E~

extent to 是习语
A 后面to which bla bla定语从句
然后light不能自己turn
所以被动
这个题貌似是og的

请斑竹帮忙看看这个题啊，是大全370的，答案似乎给的是D,想问A为啥不对尼？？

extent to/of都可以
但是后面shift要被动
所以选A

I think "extent to which" is a correct use

我的理解：这个to是定语从句的介词前置，作为shift不及物动词的介词，改变下语序：light from a distant galaxy has been shifted to the extent toward the red , or long-wave（来自于遥远星系的光，向光谱红端或长波移动的距离）。后面半句是作为long-wave的同位语，同时也表明了shift这个动作的发出对象是the rapid motion ，因此light...要使用被动语态。

大晚上刷题忽然看见了N年前的帖子，个人认为E选项不优选，因为它是hidden word：the shift of的shift明显是个n.，但他却要表达动词的意思，所以这种情况下答案真正的verb更好一些？

请NN赐教！
