What if one story-ID question asks about a series of stories, while another story-ID question asks about a particular story which happens to belong to that series. Are they duplicates? If they are duplicates, which one should be closed, or does it depend on which was posted first, or on which is the better question or has the better answer?
(I have no definite opinion on the matter. I don't even see the point of closing story-identification questions at all, seeing as they will not be deleted and will remain on the site forever.)
