我想知道的是D为什么是削弱，谢谢

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.

Conclusion: any workers who participate in a Quality Circles program will, as a result, become less satisfied with their jobs.

D says that some worker actually increased their work satisfaction while participating in Quality Circles, albeit in another company. This is a direct rebutal to the above conclusion, which does not limit itself only to Qaulity Circle at Lark Manufacturing.

我觉得题目中有一个关键点：any workers who participated in a QC，any workers指得是包括LMC以外其他公司的workers。已开始没注意，所以整题看上去很混乱。觉得GMAT的逻辑体很多情况下看快了就会觉得很复杂，但事实上是自己没看到小词。
A：因为第二次survey进行的时候LMC正处于传闻要裁员中，所以survey的结果LMC员工不满不具有代表性，属于样本问题；
B：LMC与QC无关的员工满意度也下降，说明是LMC的其它原因，而不是QC，导致员工不满（比如要裁员）
C：直接反对的survey结果，说LMC参与QC的员工体现了满意（2 indicators）
D：其他公司参加QC的员工没有出现满意度下降，说明可能是LMC自身的问题，而不是QC的问题
E：参加QC的员工起初认为参加能提高工作境况。（无关。描述了员工的动机，但是跟满意度下降没有关系；可能中国人的脑子会转一下，既然开始时觉得能提高工作境况，但是后来没有提高，所以不满意，但是题目没有给出开始时和2年后在工作境况上的差别）
