123. Outsourcing is the practice of obtaining from an independent supplier a product or service that a company has previously provided for itself. Since a company’s chief objective is to realize the highest possible year-end profits, any product or service that can be obtained from an independent supplier for less than it would cost the company to provide the product or service on its own should be outsourced.

Which of the following, if true, most seriously weakens
the argument?

(A) If a company decides to use independent
suppliers for a product, it can generally
exploit the vigorous competition arising among
several firms that are interested in supplying
that product.
(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.
(C) Certain tasks, such as processing a company’s
payroll, are commonly outsourced, whereas
others, such as handling the company’s core
business, are not.
(D) For a company to provide a product or service
for itself as efficiently as an independent supplier
can provide it, the managers involved need to be
as expert in the area of that product or service
as the people in charge of that product or
service at an independent supplier are.
(E) When a company decides to use an independent
supplier for a product or service, the independent
supplier sometimes hires members of the
company’s staff who formerly made the product
or provided the service that the independent
supplier now supplies.

自己补充一下，希望最好能有哪位好心人给帮忙解释比较一下选项B和C，万分感谢

个人认为B直接在反对结论，不是any product or service that can be obtained from an independent supplier for less than it would cost the company to provide the product or service on its own should be outsourced。 而c更像是在说事实上那些service常outsourc哪些不，没有削弱的功效，个人意见，仅供参考

一定搞清楚问题让你weaken什么。只要其他公司做outsourcing比自己公司做成本低，就应该把业务outsourcing.B选项直接告诉你这种方法太绝对。因为outsourcing容易泄密。LZ选择C肯定是过度推理了。C只是告诉我们两种具体的outsourcing和不outsourcing的对象，并不能直接说明全部outsourcing的坏处。B可以。

似乎明白了一些了，呵呵。谢谢两位的帮忙
