In a study of the effect of color on productivity, 50 of 100 factory workers were moved from their drab workroom to a brightly colored workroom. Both these workers and the 50 who remained in the drab workroom increased their productivity, probably as a result of the interest taken by researchers in the work of both groups during the study.
Which of the following, if true, would cast most doubt upon the author’s interpretation of the study results given above?
(A) The 50 workers moved to the brightly colored room performed precisely the same manufacturing task as the workers who remained in the drab workroom.
(B) The drab workroom was designed to provide adequate space for at most 65 workers.
(C) The 50 workers who moved to the brightly colored workroom were matched as closely as possible in age and level of training to the 50 workers who remained in the drab work-room.
(D) Nearly all the workers in both groups had volunteered to move to the brightly colored workroom.
(E) Many of the workers who moved to the brightly colored workroom reported that they liked the drab workroom as well as or better than they liked the brightly colored workroom.

B because since the drab room could only accommodate about 65, productivity was taking a beating. Since 50 of them were moved to another room, the productivity of people inside the drab room increased and ppl in the bright room increased. (However I now realize that I have assumed that the bright room can accommodate 50 as well - which should be ok otherwise productivity may not increase).

Jay mentions E - but then why would the productivity of both the group increase (specially the ones who moved to bright room)?

ACC to me it is B)
The reason for increased productivity is, according to researchers, the interest of the workers in the research performed.
Acc to B, the reason for increased productivity is not the interest of the workers but the increased work space. Thus B) denies the conclusion of the scientists

if the low productivity was because of inadequate accomodation/space, then the new production is because of adequate accomodation/space not because of color/light.

and B says the same.

Premise:
1) study of effect of color on productivity
2) 50 of 100 factory workers moved to brightly colored room
3) Those in brightly colored room and those in drab room increased their productivity

Conclusion:
4) Increased productivity most probably due to interest taken by researcher in the work of both grps

We want to find a choice that says productivity went up not because of the interest shown by the researchers.

A) Doesn't explain why productivity went up for some other reason
C) Same as A. Doesn't provide an alternative explanation
D) Irrelevant
(E) again, does not provide us another reason why productivity went up

B is the best. If the room is meant for 50 workers, then 15 are probably bumming around... so productivity went up coz headcount is now maximized.

I think B is answer.

Only B explains alternative reason for why productivity increased.

I feel its not a great question.
B, it is, but is better of the worst and is quite far-fetched.
With a lot of assumptions with the main one being, increase in space => increase in productivity..... One would go for B. Hope such questions don't appear actually.
Thanks!

At the first time, I chose (D). But after reading again the argument and explanation of guys above, I understand why (B) is correct. Thanks :D
