I suspect we're doing Duolingo's work for them, partly. As phrases become more complex, there will be more different ways of saying it, so the higher we go, the more likely we will run into this problem. Regional idiosyncrasies complicate things too. I just report my answer if I think I got it right, and try to remember the wording of Duolingo's answer next time.
