terminology - Is there a name for the set of possible ***direct*** answers to a question?

For example, the set for the question "did you go to the store?" would be {'yes','no'} but not include '7', and for "how old are you?" would be the set of positive integers but not include 'by car', and for "how did you get here" would include 'by car' but not 'Jupiter' , and so on.

An indirect answer might challenge the question. For example, the direct answers to "have you stopped beating your wife?" would be 'yes' or 'no', but hopefully neither is correct, so you would challenge the question by saying "I never beat my wife". Hopefully this is the correct answer, but you have to go meta to give it.

Also, are there other, correct terms for what I called "direct" and "indirect" answers?

Thanks
