In context, when would it be appropriate to use "answer" or "response"? I always tend to use "answer" personally, but I have always this nagging feeling I could be wrong.
Response is a very broad term, and includes all reactions to a stimulus.
Answer is more specifically a response to a direct question.
One can always respond to anything (an event, an injury, a letter, a speech, a question...) but one can only answer a question. As Emanuil said, it's also possible to respond to a question without actually answering it; listen to politicians being interviewed.
"response" requires something you are responding to and it doesn't have to contain an answer. You can respond to a question without answering it.
"Response" is from Latin (responsum), while "answer" is from Old English (noun: andswaru, verb: answarian.).
I always use Fowler's rule: Prefer the Saxon word to the Romance.
