标题: OG73 用LAWYER方法想不通

73. In comparison to the standard typewriter keyboard, the EFCO keyboard, which places the most-used keys nearest the typist’s strongest fingers, allows faster typing and results in less fatigue. Therefore, replacement of standard keyboards with the EFCOkeyboard will result in an immediate reduction oftyping costs
Which of the following, if true, would most weaken the conclusion drawn above?

(D) The more training and experience an employee has had with the standard keyboard, the more costlyit is to train that employee to use the EFCO keyboard.

从LAWYER方法来看，本题属于“因果型结论”。
因：replacement of standard keyboards with the EFCOkeyboard
果：an immediate reduction of typing costs

WEAKEN该结论的方法包括：A。是其他原因或可能导致该结果。B。割断因果：或有因无果或有果无因。C。因果颠倒了。D显示因果关系的资料不准确。

答案属于哪一类呢？

谢谢

还有一点疑惑，请大神指点。

本题中 PREMISE：In comparison to the standard typewriter keyboard, the EFCO keyboard, which places the most-used keys nearest the typist’s strongest fingers, allows faster typing and results in less fatigue。

CONCLUSION：Therefore, replacement of standard keyboards with the EFCOkeyboard will result in an immediate reduction of typing costs

要求：WEAKEN

我猜测正确答案：有其他原因result in an immediate reduction of typing costs 或者 replacement of standard keyboards with the EFCOkeyboard will NOT result in an immediate reduction of typing costs

结果题目就做错了。
我的分析过程错在了什么地方呢？

谢谢

Because "replacement of standard keyboards with the EFCOkeyboard will NOT result in an immediate reduction of typing costs" if D is right. You already figured out the possible answers but you did not pick the correct answer choice thereafter.

Focus on IMMEDIATE COST.
