请问og-143 e

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.

请问E算不算加强了General Manager的言论。我在看OG时比较困惑，因为很多选项到底是加强还是无关，或是削弱还是无关，OG上说的模棱两可，不知道它确切的意思。如果题目变一下，考另外的选项会死得很难看

请牛牛指教

我也顶这题！！！！原文中根本就没有提到cost的问题，C看起来更像是无关选项啊？！

A & B & D - "wu guan"/no effect on the conclusion

C - undermine GM's opinon, if employees experienced with M cost more than those with V, there will be more overhead to the company if it uses M, because it has to pay more on salary, which is one more reason to go with V.

E - strengthen GM, if V is more expensive to maintain, the GM just finds a good reason to stay with M, because the company will save money on it.

I guess you might confuse the two meanings of "wu guan". "Wu guan" in Strengthen or weakening/undermining questions refers to any choices which do not have any effect on the conclusion, neither strengthen nor weakening; The "wu guan" JOANRAIN mentioned in your answer refes to new information (other than those mentioned in the stimulus) in the answer choices, and the question HAS TO bring new information to strengthen or weaken an argument.

Don't know if it helps.
