My answer shouldn't be accepted
Sometimes when I see another correct solution for a translation I think: "hmm my answer just doesn't seem right" . So I am suggesting that duolingo puts another option in report problem called: "My answer shouldn't be accepted." What do you think ? :P
Do you mean in the real world translations? If so, then I believe you can either edit your version, or trust that by consensus the best translation has not yet arrived. There are language experts in this "forum" and it is highly probable that they will catch the less than ideal translations.
