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 (B) Vernon itself acts as an independent supplier of specialized hardware items to certain manufacturers that formerly made those items themselves. (E) 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. 我选B，答案是E 请问问题出在哪里，请求高手解答，感谢 --
