The manager wants to ensure that standards of quality remain constant from week to week. The manager, therefore, claims that out of 2,000 light bulbs produced per week, 500 light bulbs are rejected. Of the following, the best criticism of the manager’s plan is that the plan assumes that (A) light bulb manufacturers cannot accept all light bulbs that produced (B) the overall quality of the light bulbs would not be improved if the total number of light bulbs produced were reduced (C) each light bulb that is reviewed is worthy of being reviewed (D) it is difficult to judge the quality of a light bulb (E) the 1,500 light bulbs that are accepted will be of the same quality from week to week 选E有点想不明白哦，我认为题目说为了使质量标准不变，每星期生产的2000灯泡都有500个被退回去作者: balapupu 时间: 2011-10-4 20:43
对啊~~ 但是你看问题是：反驳经理的这个计划，因为经理的assumption是？ 就是E喽·~剩下的1500个的质量一定是好的~~这个不一定啊~~万一这批中坏的多~有600个不好的呢~~那质量不能保证了~作者: UlysessHope 时间: 2011-10-4 21:11
20. A light bulb company produces 2,000 light bulbs per week. The manager wants to ensure that standards of quality remain constant from week to week. The manager, therefore, claims that out of 2,000 light bulbs produced per week, 500 light bulbs are rejected.
premise：the company produces 2000 LB per week additional premise: the manager wants to ensure that the standards of quality remain constant conclusion: the manager claims that , 500 out of 2000 LB produced per week are rejected assumption: the remaining 1500 LBs will be of the constant quality
if we negate E, "the 1,500 light bulbs that are accepted will be not of the same quality from week to week", then the quality of LBs remained will not be constant, thus weaken the manager's plan
