[rhea]

The peaks of a mountain range, acting like rocks in a streambed, produce ripples in the air flowing over them; the resulting flow pattern, with crests and troughs that remain stationary although the air that forms them is moving rapidly, are known as "standing waves."

(A) crests and troughs that reaming stationary although the air that forms them is moving rapidly, are

(B) crests and troughs that reaming stationary although they are formed by rapidly moving air, are

(C) crests and troughs that remain stationary although the air that forms them is moving rapidly, is

(D) stationary crests and troughs although the air that forms them is moving rapidly, are

(E) stationary crests and troughs although they are formed by rapidly moving air, is


在刪除了動詞的問題後,只剩下C和E,
我不太明白為什麼答案是C而不可能是E?

請大家幫幫忙,謝謝!

E比較容易造成Ambiguity...
they指的是哪一個?both or only troughs?
是stationary crest only or stationary crests and stationary troughs?

還有E用被動來表達基本上違反ETS主動優先原則!
