prep-1-36 请教一句句子的翻译

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.

(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.

(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.

标准答案选E。

解释里面说道

经理们解放出来从事核心业务，至少对收入是一个正向作用，因此不管成本如何变，对利润也是一个正向作用

但是，我怎么觉得这句话的意思应该是“参加那些相对没效率的工作占据了很多经理的时间和精力，这些时间本应该花在核心业务上。明显是削弱嘛。请高人指教！

你翻译得没错，但理解上有些小问题

原文大意：

    因为——外包业务会降低成本，自己生产会降低利润（增加成本）

    所以——外包。

答案E恰好是说：经理在外包部分业务之后，就可以把精力集中在提高核心业务上，从而令利润增加。 这个答案是支持外包的，是说外包有利于提高公司利润。所以是支持，不是削弱。

谢谢LS哦！

楼主的解释是哪里 下到的? 是否能够分享 ,我都快做完了,都不知道有PREP CR 的解释...

我的理解

E 是 加强.因为oursouce他们原来成本控制不如别人的业务(inefficiently performed task), 可以释放更多的时间去CORE business, 对提高利润是正向作用.

干扰选项我认为是 A.现在还有点迷茫

A 说 V 没有计划做OURSOURCE 的业务是其他供应商不能提供更低COST的,那意味V 保持了 这部分的优势,加上现在OUTSOURCE的优势,成本更低,PROFITS 不是也增加吗
