I stumbled upon a question today that really qualifies to "lacks minimal understanding".
No other close vote really fits here. It's the complete python code (except that print should have lowercase p) needed for the question. I guess you could shoehorn it into "details or clarity" but IMO it's a pretty clear question. You could also (as we did in this case) find a duplicate that answers it. But it's not really reasonable that we should have to find dups to be able to close questions like this.
EDIT:
Another better example:
The question is very clear, and the answer is a simple "yes".
