标题: OG 11-90
The peaks of a mountain range, acting like rocks in a streambed , produce ripples in the air flowing over them; the resultig flow pattern, with crests and troughs that remain stationary although the air that forms them is moving rapidly, are known as "standing waves".

C) crests and troughs that remain stationary although the air that forms them is moving rapidly, is
e) stationary crests and troughs although they are formed by rapidly moving air, is

为啥e当中although后面跟的东西是awkward and unclear? 说unclear是不是因为they指代不清？还有其他造成awkward的原因吗

c中的that指代crests and troughs?that能指代复数吗？就算能，还是指代不清啊，到底指crests还是troughs

另外还有个小问题：文中未划线处的acting like好想也有问题，按照og11-56的说法，acting like只能用在人上，一丝是behave，而act as用在物杀，表示物的性质，但这里指的是物，却用ack like

因为用被动了，og中对于被动的评价一般是“weak & unclear”，就像你说的，they的指代不清

c中的第一个that是定语从句的引导词，不是代词，所以不用复数，它具体指代哪个我们也不知道，也不需要知道，因为这个小问题是所有选项中错误最小的

这里的acting like不是act like的短语，而是a like b act...，like是做对比
