CR: Some sociologists posit that unrest in the workplace

[direstraits007]

Some sociologists posit that unrest in the workplace is primarily a result of agitation by outsiders and other societal influences. An incident recently occurred at factory X in which the workers went on strike to protest the poor quality of the seats they use while working at the conveyor belt.
Which of the following, if true, provides the strongest support for the sociologists’ theory with respect to factory X?
A. A report on the dangers of non-ergonomic seating that was televised on a national news program.
B. Many of the workers at factory X are well-read and politically active.
C. There are many factories other than factory X in which the same conveyor belts and seating are used, and
there have been no strikes at these factories.
D. Some cases of unrest in the workplace result from worker dissatisfaction.
E. There is no single problem with either the conveyor belt or the seating at factory X that can be said to have caused the workers to strike.

OA:A

I'm confused between A and E and I chose E because since as it is stated in E that "There is no single problem with either the conveyor belt or the seating at factory X that can be said to have caused the workers to strike." which means there must be some other agitation by outsiders and other societal influences which happened to employees and that is why they went on strike.

Please correct me if my logic has flaw.

Thanks

I think it is A.
choice A mentions some outside influence like the national news program.
choice C only tell you that it was nothing to do with conveyor belt or seating. so, the reason could be something from outside or it could be some other issue in the factory other than conveyor belt and seating.

I agree with Raja above, though I believe you meant, Raja, to say E rather than C in your post.

While E is indeed interesting, and shows that something other than the seats themselves must have caused this protest, we do not know that the cause was outsider agitation of social influence. It could well be that the strikers were agitated from within.
