PREP
外包part of its product->↓cost，↑profit
(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.
C 就算有outsource，没有多少外包商可以变成competitor
可能会对profit产生影响，先留着
(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.
E 时间效率筹划的改变使得V的efficiency可以提高

再来看OG:
任何可以外包的都外包->最大程度上boost profit
(B)  Successful outsourcing requires a company to provide its suppliers with information about its products and plans that can fall into the hands of its competitors and give them a business  advantage.

两道题的区别就是 一个是把 part of its work外包，一个是只要能外包的都外包出去。
part外包的情况下，就像苹果，研发不会外包吧？只是组装和生产需要外包，而真正值钱的部分就在研发上。说明重要的部分是不会外包的！！！prep题中的C在这种情况下无须担心。但是OG-全盘托出可能会导致技术泄露，知识产权问题等~

我第一次做prep的这道题也选了C。。细想一下，就算被competitor抢占了生意，对profit会有影响吗？还是来看苹果的例子.. 零部件非正版卖的很多啊，但是核心技术没被盗取，所以影响没那么大吧比起OG的全盘托出

=。=这个例子可能扯远了，主要想呈现两个题目的不同.. .. 至于prep题CE的对比.. ..
Which of the following, if true, most strongly supports the prediction that Vernon's plan will achieve its goal?
目的就是boost profit，更多的是对结论的补充E，而非排除其他可能C（是不是support的情况下就是填gap而strengthen就是排除其他可能啊？？求大佬指点）
