189. 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
这道题如果单看as an expert does 和Like an expert是无法判断的，两者意思一样，结构都正确。那么我们继续往下读：只有C： diagnosing equipment breakdowns or deciding whether to authorize a loan这两部分遵循平行对称。而且such...as用于举例子真确，应此C真确。
