Critical Reasoning

Lark Manufacturing Company initiated a voluntary Quality Circles program for machine operators. Independent surveys of employee attitudes indicated that the machine operators participating in the program were less satisfied with their work situations after two years of the program’s existence than they were at the program’s start. Obviously, any workers who participate in a Quality Circles program will, as a result, become less satisfied with their jobs.
Each of the following, if true, would weaken the conclusion drawn above EXCEPT:
(A) The second survey occurred during a period of recession when rumors of cutbacks and layoffs at Lark Manufacturing were plentiful.
(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.
(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.
(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.
(E) The machine operators who participated in Quality Circles reported that, when the program started, they felt that participation might improve their work situations.


OA: after some explanations

A. Weakens - Employees possibly dissatisfied due to layoff rumours.
B. Weakens - Both particpants and non participants reported dissatisfaction. So real reason something else.
C. Weakens - Says that they actually exhibited 2 indicators of job satisfaction.
D. Weakens - They themselves felt that their work satisfaction improved earlier.
E. Irrelevant - Talking about how they felt when the program started.

Answer : E.

E is definitely not relevant to the scope of the argument.
All others weaken the conclusion.

how C weakens the argument ? it says they exhibited their satisfaction thr something.

Read Opt C again.
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.

It says those who participated in QC showed improved job satisfaction (and goes on to list 2 indicators) which is the opposite of the conclusion in the argument.
Hence it weakens it.

hey thanx a lot buddy !!

I think it's should be E
