书上的答案是选A，不知为何

are those These cups are ours. those are ___. what are those?的正确答语应该是They are……还是Those are…… 翻译：For those who are in wheelchairs... how lucky those people they are those are not your business.对不对? Those are erasers.(改为单数句） I wonder if those sentences are right ”What are thes? Those are books.”有没有错？ here are three kinds of people: those who can count and those who cannot.
