OG189: such as A or B?

189. Proponents of artificial intelligence they say 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 whetherto 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

我认为正确答案C有毛病。

选项C中，such purposes as A or B， 不应该用or,应该用and. 是吗？

楼主为什么这么说呢?

这里主要是用两个目的的关系来判断是and 还是or 吧, 而在这里用and 还是or 的差别不大
