We get scores of low-quality or homework questions where someone just pastes a question into the question box and hits submit. From the help center:
Do we accept basic level/homework questions?
Yes, we do. However, please provide an indication of what you are not understanding/need clarification on and your attempts at solving it, so we have a clear indication of where you are stuck. This goes for all questions, not just homework. If you have just written out your assignment, your question will be closed. You might want to read this article and this article on writing the perfect question.
Yet there doesn't seem to be an (easy) close reason that fits this situation. Do we just downvote these questions and move on?
If we actually want to close these questions, could we get another close reason added to accommodate that? We could (continue to) type text into the custom off-topic field, but these questions soak up enough review time anyway; I'd prefer to streamline dealing with them and moving on.
Here is an example question where this close reason would've been selected, and there are plenty more examples available.
