prep 08 难题求解释

玛德滞涨

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.
(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.
这个是prep0708里面的，答案选E我选的C
虽然说C的竞争和公司获利不直接相关
我觉得E也不是直接相关吧 和boost profit
难道说managers运用效率更高就一定能使公司profit增加吗 也不一定吧 文章也没给这方面暗示啊 求解

方案推理与因果推理的区别就是：有方案，待评价。
如果评价了方案，就是因果推理了。
SPK004题干中已经评价了方案，所以其实是一个因果推理。但由于方案推理与因果推理有交集，你当成方案推理做也可以。只不过方案推理的CQ都是针对assumption的，而因果推理的CQ的方向要更多一些。这题答案又刚好是Defender类加强，凑巧了。你想想为什么方案推理的CQ都是针对assumption的？因为方案推理没有结论啊！前提不能是假的，不质疑assumption题没法做了。
而因果推理，除了在assumption上做文章，我还可以对因果关系做文章吧（因果倒置，无因果关系）？

这题CE挺不容易分辨的，我好像做的前两次都错了，后来再遇到答案记住了，自然就不错了，但是不保证以后遇到类似的不会再错。
我后来也想了很久，我觉得这题之所以会错，跟Helr分类有关（Helr别砍我）。
这题的CE看起来都像方案类推理的CQ：
C. 方案无副作用
E. 方案有效

坦白来讲，C和E都跟方案的目的boost profit有一个gap:
C. competition和boost profit之间有gap
D. top managers spend more time on core business和boost profit之间也有gap

这时就要看哪个的gap小了。C说的是别人怎么样，E说的是我怎么样，方案的目的是boost我的profit。我觉得E与目的的gap更小。

我觉得出题的人在出题时，把C当成一个与目标无关的一般事实了，但没想到变成popular的迷惑选项了。你注意看C说的是一个客观存在的“事实”，所以C中从头到尾都没出现跟Vernon有关的内容。但你看E，说的都是Vernon，这是一个针对Vernon“订制”的答案，是有关的。
