### HideShow timer Statistics

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
(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

I will go for E, as the quality parameters for passing the bulb have to be same, all the 1500 that pass are and should be same

I would go with B. The manager wants to manufacture 2000 bulbs, and reject 500 every week.
He is missing the point that, why can't they just manufacture 1500 PERFECT bulbs or lets say 1700 with only 50 bad and yielding 1650 PERFECT or even with 200 bad yielding 1500, instead of 2000 and then rejecting 500.

E sounds right as per the #s. But not as good as B.

Whats the OA ?

OA is E.

My choice is the same as your. I realized that I missed the point: remain constant from week to week. Thank you for your discussion.

guys - i just don´t get it why it is not B, as B "the overall quality of the light bulbs would not be improved if the total number of light bulbs produced were reduced" perfectly points out that the rejection doesn´t make any sense! can someony help me on that?

thanx

I think the argument does not focus on impovement in quality of the the light bulbs. Do you think so?

I agree. The focus isn't on the improvement of quality but rather the consistency of quality from week to week. Hence, B is out of scope and E is the best answer.

I am for E and let me try to explain why not B.
rejecting 500 bulds each week neither ensure the quality of 1500 selected bulbs nor the constant quality.

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

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

I was between A and E.

B won't work because who is to know if fewer bulbs produced would actually result in better quality.
C and D do not pertain to the managers plan.
Choice A is sort of coming out of no where now that I re-read the question...

I will go with E.
