OG10-57

57. 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

OG的解释：E is faulty because it contains no verb to express the action performed by the rapid motion.

但是by the rapid motion 不能修饰名词the shift嘛？是仅仅因为隔的太远还是因为不能修饰？

个人意见，不是NN，我觉得E中的shift是名词，而动词优于名词，所以不选。

再问一下，这道题的答案是选第一个吗？谢谢。

解释red shift"是 动作 而不是状态,所以用动词.而不用表达状态的名词

是选A

I feel that the key point here is "extend" .  Most of times, I see extend of + gerund
