Answer: The answer to the question you are looking for is choice d: "above".
Step-by-step explanation: Choice "A" does make sense, but why would birds want to go around clouds if they are trying to get cool air? Choice "B" doesn't make sense, why would birds want to go after clouds they are trying to get cool air? Choice "C" doesn't sound like the correct answer, again, why would birds want to do that if they are attempting to get some cool air? Choice "D" does make sense, why wouldn't bird want to do above the clouds if they simply trying to get some cool air up in the sky?
