Outsourcing is thepractice of obtaining from an independent supplier a product or service that acompany has previously provided for itself. Vernon, Inc., a small manufacturing company that has in recent yearsexperienced a decline in its profits, plans to boost its profits by outsourcingthose parts of its business that independent suppliers can provide at lowercost than Vernon can itself.

Which of thefollowing, if true, most strongly supports the prediction that Vernon's planwill achieve its goal?

(A) Among the parts ofits business that Vernon does not plan to outsource are some that requirestandards of accuracy too high for most independent suppliers to provide atlower cost than Vernon can.

(B) Vernon itself actsas an independent supplier of specialized hardware items to certainmanufacturers that formerly made those items themselves.

(C) Relatively fewmanufacturers that start as independent suppliers have been able to expandtheir business and become direct competitors of the companies they oncesupplied.

(D) Vernon plans toselect the independent suppliers it will use on the basis of submitted bids.

(E) Attending tocertain tasks that Vernon performs relatively inefficiently has taken up muchof the time and effort of top managers whose time would have been better spentattending to Vernon's core business.

答案E

提问：

E项，领导层更多的参与到了核心业务中，这肯定使公司比外包前更有效，并不能说明一定可以降低成本的选项，E选项还是有不确定性吧。

A项，说没有outsource的项目都是不能降低成本的项目，那么outsource的项目“都是”降低成本的项目，从而可以low cost。不对吗？

support并不是要求证明结论  提高结论成立的可能性也是support

A 其实算是无关 因为有些业务不能通过外包降低成本 不等于另外的业务可以外包降低成本

E的支持更直接 performs relatively inefficiently 就说明 可以变得更为efficiently 提高效率就是降低成本 这不属于额外信息 而是common sense
