E is the only option that directly support the conclusion
It actually is filling the gap between premise and conclusion.

IMO E

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 ---incorrect, Manager's goal is to ensure the standard not to market every light bulb.

(B) the overall quality of the light bulbs would not be improved if the total number of light bulbs produced were reduced ---incorrect

(C) each light bulb that is reviewed is worthy of being reviewed -- incorrect
(D) it is difficult to judge the quality of a light bulb - incorrect,
(E) the 1,500 light bulbs that are accepted will be of the same quality from week to week -- correct

yeah B and E are close..E will stand out...
The manager thinks that the 1500 bulbs produced all will the best quality....

It was a nice criticism for that kind of aspect. The four options might be right as long as they can deal with it. However, they are right that E was the correct criticism, unless they might be defended into the right action.

The question stem is a tricky one. There is the term ' best criticism', meaning weaken but at the end, the stem says 'plan assumes'. So we need to find the assumption and not weaken the argument.
This is my take way from this question.

the manager wants to ensure the quality remains constant from week to week . but the negation of E clearly states otherwise.

Manager's goal is to improve quality by reducing production from 2000 to 1500. Therefore he assumes that production at 1500 will result in consistent quality light bulbs.

A criticism would be that the quality will not be consistent at 1500.

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

Wrong because marketing is out of scope

(B) the overall quality of the light bulbs would not be improved if the total number of light bulbs produced were reduced

I struggled with this one. It seemed good at first but I didn't like the statement "not be improved" since it also means "remain consistent or decrease". I believe the manager wants to keep quality consistent.

(C) each light bulb that is reviewed is worthy of being reviewed

Out of scope.

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

Out of scope.

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

Since this specific answer hasn't been touched on much, can someone help me find out where I have gone wrong in my reasoning?

When I answered this question I chose answer D. I chose it because the criticism I made of the manager's decision before looking at the answers was that '500 is an arbitrary number. Why can't we just test each light bulb on its own merit?'.

Answer D: The managers plan assumes that 'it is difficult to judge the quality of the light bulb' matches that criticism because if it were easy to judge the quality of the light bulbs there would be no problem in testing all of them and not arbitrarily getting rid of 500 light bulbs. That is to say, if it were easy to judge the quality of the light bulb then maintaining standards of quality week to week wouldn't be an issue.

Answer E correctly criticises the manager's assumption that quality would stay the same on a week to week basis just because only 1,500 light bulbs were selected, but doesn't answer the question 'why arbitrarily select 500 light bulbs instead of just testing each one on its own?' The best way to maintain consistency in quality would be to make sure that each light bulb is up to the company's quality standards. And once again, if it were easy to judge the quality of the light bulbs then this would be the best solution to the problem so D is a more encompassing answer than E.

To summarize. If a manager approached me with this plan I wouldn't ask him 'but how will you know that the 1500 you do select will be of the same quality from week to week?' but rather I would ask him 'Why can't we judge each light bulb we produce on its own merit and ensure through those standards that the quality is the same from week to week?'

I hope I've been clear in sharing my thoughts and I definitely appreciate the feedback. Apologies if this turns out to be convuluted.

The manager wants the standard of quality of the bulb being sold each week to be same . He assumes that there are about 500 bulbs each weak whose quality deviates from the standard of quality. That's why he want to take them out of the lot of bulbs being marketed so that the remaining lot of 1500 bulbs is of same standard of quality each week. However, this assumption is not supported by any reasoning, and hence is unfounded ; Therefore, E is the best answer.
