I am looking for a word similar to "uninformative" but not quite, since "uninformative" applies to the answer but I want the word for the corresponding question with an answer that is necessarily uninformative. Arguably, rhetorical questions are a subset of this sort of question, but there are other types as well so that's not quite satisfactory. I've thought of "useless" and its synonyms but was wondering if there is a term specifically for questions of this sort.
The context, for me, is that people frequently ask "is this possible?" in terms of work projects, the answer to which is always "yes", but they really needed to ask "is this practical" or "how long will this take?"
