Outsourcing is the practice of obtaining from an independent supplier a product or service that a company has previously provided for itself. Vernon, Inc., a small manufacturing company that has in recent years experienced a decline in its profits, plans to boost its profits by outsourcing those parts of its business that independent suppliers can provide at lower cost than Vernon can itself.
Which of the following, if true, most strongly supports the prediction that Vernon's plan will achieve its goal?
(A) Among the parts of its business that Vernon does not plan to outsource are some that require standards of accuracy too high for most independent suppliers to provide at lower cost than Vernon can.
(B) Vernon itself acts as an independent supplier of specialized hardware items to certain manufacturers that formerly made those items themselves.
(C) Relatively few manufacturers that start as independent suppliers have been able to expand their business and become direct competitors of the companies they once supplied.
(D) Vernon plans to select the independent suppliers it will use on the basis of submitted bids.
Attending to certain tasks that Vernon performs relatively inefficiently has taken up much of the time and effort of top managers whose time would have been better spent attending to Vernon's core business.
问题分析：A围绕的是vernon一些不计划outsource的计划谈的，原文围绕的是一些准备outsource的计划谈的，范围没交集，干掉。
B说vernon可以作为别人的独立供货商，原文玩命说vernon要别人给他供货，这个选项说vernon准备供给别人货，方向完全反了，干掉，无关。
C说几乎没有生产商刚开始作为独立的supplier而后来变成直接竞争对手，没说过，干掉。
D说vernon选择供货商的标准是什么，文章显然没提，干掉。
E说如果从事一些不重要的事情会影响这个公司效率，正好可以支持vernon把这些task外包，留着。
