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."

I had chosen C becuase it sounds better than E. However, I do not understand the OE about why E is wrong.

Paul got a fairly acceptable explaination here.

Quote:
C must be it. E does not sound right to me at all
E) the resulting flow pattern, with stationary crests and troughs although they are formed by rapidly moving air, is known as "standing waves".

"although" is supposed to set some contrast. What kind of contrast does "although" sets here? None. The sentence illogically means: Stationary crests and troughs, despite being formed by rapidly moving air... This is out

C establishes the right contrast and compares the right elements. C means that crests and troughs remain stationary despite the air moving rapidly around them. You see the contrast? Despite the movements, they remain stationary.

I still don't see the difference. Didn't he say the same thing in his second and third paragraph? Only he called the one for (E) illogical contrast.

(C) uses the verb "remain" to describe the action of "crests and troughs". So (C) means something acts some way, although something else acts a certain way.

(E) uses "stationary crests and troughs" as a group of nouns, being described as "stationary". The contrast was made to "stationary crests and troughs" as a whole and this is incorrect. While the contrast only needs to show the different in "action".
