143. Division manager: I want to replace the Microton computers in my division with Vitech computers.
General manager: Why?
Division manager: It costs 28 percent less to train new staff on the Vitech.
General manager: But that is not a good enough reason. We can simply hire only people
who already know how to use the Microton computer.
Which of the following, if true, most seriously undermines the general manager’s objection to
the replacement of Microton computers with Vitechs?
(A) Currently all employees in the company are required to attend workshops on how to use
Microton computers in new applications.
(B) Once employees learn how to use a computer, they tend to change employers more
readily than before.
(C) Experienced users of Microton computers command much higher salaries than do
prospective employees who have no experience in the use of computers.
(D) The average productivity of employees in the general manager’s company is below the
average productivity of the employees of its competitors.
(E) The high costs of replacement parts make Vitech computers more expensive to
maintain than Microton computers.

A为什么不对?所有的employees都要参加workshops,学习M computers怎么运用于new applications. 这其中也包括general manager指的已经会使用M computer的员工.   培训费并不能省下. 削弱了结论. 怎么不对了?

继续顶～～　直到有人理

A是irrevelant,因为讨论的是关于new application的培训。

答案是什么？ C 吗？
