### HideShow timer Statistics

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, suggests that the company reject 500 of the 2,000 light bulbs it produces each week.

Of the following, the best criticism of the manager’s plan is that the plan assumes that

(A) light bulb manufacturers cannot market every light bulb that they produce
(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 think B is out of scope since it is talking about increase in quality whereas we aer debating about maintaining the quality....500 0ut if 2000 bulbs need to be rejected for maintaining the quality...But what if the criteria of rejection is not known...We might reject the good oncs and retain the bad ones....This is indicated in D and it is my choice....OA please....

IMO E..

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, suggests that the company reject 500 of the 2,000 light bulbs it produces each week.

So manager is concluding that 1500 remaining bulbs will be of 'constant' quality. Criticism will be the manager's assumption that 1500 bulbs' quality will not wary from week to week. Hence E.

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

Clearly, here the manager is assuming that out of 2,000 bulbs, only 500 bulbs would be of lesser quality. Why? The defective number can be anything from 0 to 2000.

each light bulb that is reviewed is worthy of being reviewed

it is difficult to judge the quality of a light bulb

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

OA: E

The option E serves the Manager's purpose. It doesn't criticize.Can anyone please explain?

I agree. The answer is E because the manager assumes that standard of quality of those 1500 lightbulbs will not change from week to week.

E

This is the best criticism because the 1500 bulbs will not necessarily be of the same quality...

Of the following, the best criticism of the manager’s plan is that the plan assumes that

(A) light bulb manufacturers cannot market every light bulb that they produce
(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

Premise one :
A light bulb company produces 2,000 light bulbs per week.

Premise two:
The manager wants to ensure that standards of quality remain constant from week to week.

Claim:
The manager, therefore, suggests that the company reject 500 of the 2,000 light bulbs it produces each week.

A : This is irrelevant. The argument doesn't talk about marketing of light bulb.
B: The argument is not about improvement of the quality of the bulb. This argument is about constant quality of bulb week after week.
C: Some kind of rhetoric statement, not related with the argument.
D: If it is true then It is also difficult to judge all 2000 bulb then reject all 2000 bulb. Why only 500 bulb ?
E: This is the right answer, as the argument is about same quality.

IMO E

I was contemplating between B and E. However, I feel B is outside the argument or a far fetched assumption.

What level of difficulty would you grade this question?

Was considering between B & E, but finally eliminate B due to the word reduce (out of scope)
