My first answer for this was "Hol van ez a farmer?" ... that was not accepted. Should it have been? In the English sentence, there's no way to tell if the speaker is talking about one pair of jeans, or several.
Make no sense. If the jeans are these, how come you're asking for their location? One edge case is that you're in a shop with a jeans sake picture asking for these jeans in the picture. Still, very edge case.
