OG-205为什么不能选E呢???

OG 205
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."  (C)

A, crests and troughs that remain stationary although the air that forms them is moving rapidly, are
B, crests and troughs that remain 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

为什么不能选E呢,OG是这么解释的"choice E incerrectly introduces a dependant adverbial although clause into a preposional phrase (with crests....)"

请问OG这是什么意思啊?是说介词短语后不能跟ALTHOUGH 引导的从句吗??

那大家请看正确答案C,"wiht crests and troughs that remain stationary" 这不算介词短语吗?C为什么 就对呢??

请大家指点迷津~~~~~~~~

非常谢谢你的帮助,我看了之后还是不是很明白,他们说如果直接是介词短语后面加ALTHOUGH引导的从句就不可以,如本题中的E选项,但是如果介词短语后面已经有一个THAT引导的定语从句,而从句后又有一个ALTHOUGH引导的从句的话就可以,如本题中的C选项.

但我想问一下,C选项中的ALTHOUGH引导的从句是修饰什么的呢???

还有,是不是只要介词短语中的名词后有从句修饰,那么介词短语后就可以有另外一个从句呢,就象本题中的C选项一样.

ALTHOUGH引导的从句修饰 that remain stationary ；

“还有,是不是只要介词短语中的名词后有从句修饰,那么介词短语后就可以有另外一个从句呢,就象本题中的C选项一样.”

我理解如果是从句修饰名词，那么就不是介词短语后的从句了，即直接修饰介词短语，而应该理解是对名词的修饰性成分。

谢谢哦~~~~~~

也就是说,如果介词短语中的名词后出现了修饰此名词的从句,那次从句后的从句就是修饰修饰介词短语中的名词的从句的,这种修饰关系是正确的,我的理解对吗??
