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

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.
