标题: 大全-I-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.

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

(D) it is difficult to judge the quality of a light bulb（E）

(E) the 1,500 light bulbs that are accepted will be of the same quality from week to week

不太明白这个题目的意思，这个manager宣告500个被退回和他要保持一定的质量有什么关系？答案E跟它又有什么关系？

The question is what is the assumption of the plan, then the answer should be E

In order to improve quality, the manager decided to reject 500 bulbs of the 2000 produced.In fact the quality improvement can not necessarily be true unless he assumes that the 1,500 light bulbs that are accepted will be of the same quality from week to week.(if they are not of the same good quality, the manager's decision will be seriously undermined)
