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 EFCO keyboard will result in an immediate reduction of typing costs.
Which of the following, if true, would most weaken the conclusion drawn above?
(A) People who use both standard and EFCO keyboards report greater difficulty in the transition from
the EFCO keyboard to the standard keyboard than in the transition from the standard keyboard to the
EFCO keyboard.
(B) EFCO keyboards are no more expensive to manufacture than are standard keyboards and require less
frequent repair than do standard keyboards.
(C) The number of businesses and government agencies that use EFCO keyboards is increasing each year.
(D) The more training and experience an employee has had with the standard keyboard, the more costly it is
to train that employee to use the EFCO keyboard.
(E) Novice typists can learn to use the EFCO keyboard in about the same amount of time that it takes them to
learn to use the standard keyboard.
WEAKEN嘛，
找CONCLUSION,"Therefore, replacement of standard keyboards with the
EFCO keyboard will result in an immediate reduction of typing
costs."
再用有无关判断，跟cost有关的也就只有D，INDEED，答案蛮好选的。
PS,EVEN IF 按照你的想法，
关于D)the more...the more...你若产生歧义，你就把这个结构扔了，仍能
说明replacement会导致cost上的花费，那么也是起到WEAKEN作用的，不存只
说了在一半的问题，我觉得。

when dealing with CR question, it is wise to focus on the conclusion！notice there is a word “replacement”..so the GMAT official has already assumed the topic here is about people using standard computers.作者: kurtsniper 时间: 2012-8-6 20:42
