A significant number of complex repair jobs carried out by Ace Repairs have to be reworked under the company's warranty. The reworked jobs are invariably satisfactory. When initial repairs are inadequate, therefore, it is not because the mechanics lack competence; rather, there is clearly a level of focused concentration that complex repairs require that is elicited more reliably by rework jobs than by first-time jobs.
The argument above assumes which of the following? (A) There is no systematic difference in membership between the group of mechanics who do first-time jobs and the group of those who do rework jobs.
(B) There is no company that successfully competes with Ace Repairs for complex repair jobs.
(C) Ace Repairs’ warranty is good on first-time jobs but does not cover rework jobs.
(D) Ace Repairs does not in any way penalize mechanics who have worked on complex repair jobs that later had to be reworked.
(E) There is no category of repair jobs in which Ace Repairs invariably carries out first-time jobs satisfactorily.
这是一道GWD逻辑题，正确答案是A，但是对于D选项很疑惑 如果把D取非就是 “对于那些第一次工作被要求返工的人，会有惩罚” 这恰好削弱了结论，因为 如果被返工会有惩罚——所以工人不会懈怠——所以不合格的原因是他们能力不够，而非不够专注 那么为什么D答案是错误的呢
