Proponents of artificial intelligence say they will be able to make computers that can understand English and other human languages, recognize objects, and reason as an expert does-computers that will be used to diagnose equipment breakdowns, deciding whether to authorize a loan, or other purposes such as these. (A)as an expert does--computers that will be used to diagnose equipment breakdowns, deciding whether to authorize a loan, or other purposes such as these (B)as an expert does, which may be used for purposes such as diagnosing equipment breakdowns or deciding whether to authorize a loan (C)like an expert--computers that will be used for such purposes as diagnosing equipment breakdowns or deciding whether to authorize a loan (D)like an expert, the use of which would be for purposes like the diagnosis of equipment breakdowns or the decision whether or not a loan should be authorized (E)like an expert, to be used to diagnose equipment breakdowns, deciding whether to authorize a loan or not, or the like 答案选C，对其他选项的错误我没有疑问，但对C中“ reason like an expert”的表达觉得不大恰当，应该reason as an expert does才合适吧？
