49．Division Manager：1 want to replace the Microton computers in my division with Vitech computers.

Division 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 I 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 t0 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．

答案：C

我对答案没问题，只是不明白B的解释

OG的解释：B  This point suggest that hiring experienced workers will be easy and so strengthens the general manager’s argument．

they tend to change employers more readily是什么意思？

hiring experienced workers will be easy 是怎么推出来的？

望高人指点，谢谢！！！

B的意思是，一旦雇员学会了M的使用方法，他们就倾向于容易的更换雇主（也就是换工作）。自然是weaken了GM想聘用会M的雇员的论点。

至于og的解释……是不是楼主抄错了，“OG的解释：B  This point suggest that hiring experienced workers will be easy and so strengthens the general manager’s argument．”问题不是“undermines the general manager's objection ”么？

答案是A。不好意思，没写清楚

B的解释没抄错。我还是不懂为什么hiring experienced workers will be easy

有没有搞错啊,这是OG10-143题,答案不是C吗?

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.

解释:The general manager’s objection is based on avoiding training costs altogether. But if, as choice C says, hiring
experienced users of Microton computers is significantly more costly than hiring otherwise qualified people who
would have to be trained to use Vitech computers, the force of the objection is weakened. Choice C, therefore, is
the best answer.
Choices A, B, and D are all incorrect; none of them provides information relevant to an evaluation of Microton
computers as compared with Vitech computers. Choice E argues independently against replacing Microton
computers with Vitech and thus is also incorrect.

不好意思，写错了，答案是C。

但是为什么Once employees learn how to use a computer, they tend to change employers more readily than before会导致hiring experienced workers will be easy ？？

可以解释一下这个吗？

OG的解释：B  This point suggest that hiring experienced workers will be easy and so strengthens the general manager’s argument

出发点是这样的: GM的理由是"直接招会玩M的人",B说"熟练工(包括会玩M和V的)容易跳槽". 可能的结果是"招会玩M的人很容易",于是支持了GM.

我排除B的理由是:它可能推翻DM的方案. 既然熟练工容易跳槽,那么公司花钱培训就可能打水漂------新员工经过培训,玩V熟练了于是跳槽了,公司又招新员工,再培训再跳槽,如此循环.
