A large hospital network introduced a mandatory stress management program for its emergency room physicians after internal surveys revealed that nearly 60% reported experiencing chronic burnout.
Premise 1Six months after the program launched, the same physicians were surveyed again, and reported burnout levels had dropped to 38%.
Premise 2Hospital administrators concluded that the stress management program successfully reduced burnout among emergency room physicians.
ConclusionThis is a causal relationship
Stress management program --->
Reduced burnout amongst physicans.
As per gmat logic in a causal relationship THAT IS THE ONLY CAUSE. so the most necessary assumption here is that
THERE IS NO OTHER CAUSEThe conclusion above depends on which of the following assumptions?
(A) The stress management program was the primary reason physicians participated in activities known to reduce burnout outside of work.
COULD HAVE BEEN. but activities outside work? Is completely new & out of scope of argument therefore its a shell games trap..
(B) The survey used to measure burnout levels was administered under the same conditions both before and after the program launched.
(C) No significant external changes occurred during the six months that could independently account for the reduction in reported burnout.
This implies no other cause. So Correct
(D) Emergency room physicians attended the stress management program sessions at a higher rate than physicians in other departments.
The passage already tells us it was mandatory so makes no sense to challenge premise.
(E) The hospital network did not simultaneously reduce the average number of shifts required of emergency room physicians during the six-month period.
Also suggests alternative cause but we cannot necessarily be sure if shifts were the reason for burnout in particular. So eliminate
