he goal is to evaluate which option does not weaken the conclusion that participating in a Quality Circles program causes a decrease in job satisfaction.
Conclusion:
Participation in a Quality Circles program leads to reduced job satisfaction.
Weaken: Provide alternate explanations or evidence suggesting the reduced satisfaction is not caused by the Quality Circles program.
EXCEPT: Identify the option that does not weaken the conclusion (i.e., it could either strengthen or be irrelevant to the argument).
Analysis of Answer Choices:
(A) The second survey occurred during a period of recession when rumors of cutbacks and layoffs at Lark Manufacturing were plentiful.
Weaken? Yes. External factors like layoffs and economic recession could explain the drop in satisfaction, independent of the Quality Circles program.
Eliminate.
(B) The surveys also showed that those Lark machine operators who neither participated in Quality Circles nor knew anyone who did so reported the same degree of lessened satisfaction with their work situations as did the Lark machine operators who participated in Quality Circles.
Weaken? Yes. If job satisfaction decreased for both participants and non-participants, the dissatisfaction is likely unrelated to Quality Circles.
Eliminate.
(C) While participating in Quality Circles at Lark Manufacturing, machine operators exhibited two of the primary indicators of improved job satisfaction: increased productivity and decreased absenteeism.
Weaken? Yes. Indicators like productivity and reduced absenteeism suggest satisfaction may have improved, contradicting the conclusion.
Eliminate.
(D) Several workers at Lark Manufacturing who had participated in Quality Circles while employed at other companies reported that, while participating in Quality Circles in their previous companies, their work satisfaction had increased.
Weaken? Yes. Positive experiences with Quality Circles at other companies cast doubt on the claim that such programs inherently reduce satisfaction.
Eliminate.
(E) The machine operators who participated in Quality Circles reported that, when the program started, they felt that participation might improve their work situations.
Weaken? No. This statement does not address the cause of the decreased satisfaction. It only highlights participants' initial optimism but does not explain the dissatisfaction observed later. This neither weakens nor strengthens the argument and is irrelevant to the conclusion.
Correct Answer: (E)
