GMAT&LSAT-Test 2-Q18

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.

The answer is E. Can anybody analyse C, D and E? Thanks.

A，他因

B, 有果无因

C, 一般逻辑错误：survey is doubtful，one-sidedness（只说好不说坏）

D, 一般逻辑错误：insufficient sample （样本可能存在偏差）

E, 无关，work situations和satisfaction无关。

saladmimi

不同意二楼意见。

不认为C或者D存在任何的逻辑错误。偶倒认为，C是无关选项，而D则是从另一个case加强了证据。

大家有何见解？

C,D本身没有逻辑错误，是,C,D的事实表明了原文推理存在逻辑错误。
