What exactly are the the standards for asking a question in title and body?

This just came up for me because I wanted to ask a question but had to unnecessarily make my title and body longer because I was shown the ["This post does not meet our quality standards."  message][1].

So it would be nice to see **why** the title or body doesn't meet the standard and not let the users guess.
