Word to describe a question with multiple exact correct answers

Not completely sure, but I don't believe ambiguous would qualify for the exact situation I am thinking of, though perhaps I am over thinking this in general. I have a question in a short story I am writing:

Why are we driving? Why can't we teleport?

And the main character, in response would ideally reply with something to the tune of:

Well that question is rather {insert adjective}. Functionally, because it's impossible. They're jamming us. Officially, because the boss told us to. Legally, because teleporting into a classified area without clearance is illegal. Personally, because I enjoy driving and don't like the idea of my atoms being ripped apart and reassembled.

Is there a word (possibly a short phrase) that describes such a situation or would it just be ambiguous?

Such a question can said to be open-ended.

Close-ended questions are those which can be answered by a simple "yes" or "no," while open-ended questions are those which require more thought and more than a simple one-word answer. The answers could come in the form of a list, a few sentences or something longer such as a speech, paragraph or essay.

I'd like to suggest multivalent, meaning having or susceptible to many applications, interpretations, meanings, or values (as per google). However, I have to admit, I've never heard it used in exactly this manner. Open-ended (or "overly open-ended" to make it more negative) would be more common.

Collins offers multicausal
