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 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

答案选c

我想问一下b选项中的such as和c选项中的such...as 在意思上有何不同吗？查了以前的帖子，但以前的讨论没有结论，希望大家再讨论一下。

个人认为区别不大，但“语法知识点”的那个帖子里链接的such as帖子说GMAT偏好such...as，这个规律好像不是很正确，我记得做过一题是用such as的（再找找），所以，我的看法是，这个比较对于做题来说不是很重要，先用其他的语法规则讲一些选项排除掉。

请指教
