I put in "which shoes are he wearing" which also sounds odd, but since "shoes" is a plural, shouldn't it be "shoes are"? Or is this an english oddity that I'm thinking too much about? Like, "those shoes are awesome" is right, and "which shoes are you wearing" is right. I just feel like "shoes is" shouldn't be a thing.
lots of people here complaining about their use of 'is' vs. 'are' being marked wrong. i dont think it's fair to deny either since they are both equally unnatural ways of saying, "which shoes does he have on," which i believe to be the most proper way to express this question in english.
