Q27:

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?

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.

There is no company that successfully competes with Ace Repairs for complex repair jobs.

Ace Repairs’ warranty is good on first-time jobs but does not cover rework jobs.

Ace Repairs does not in any way penalize mechanics who have worked on complex repair jobs that later had to be reworked.

There is no category of repair jobs in which Ace Repairs invariably carries out first-time jobs satisfactorily.

这题怎么没找到对应原13套的题号，也就找不到讨论连接了，只好再贴帖子询问一下了，麻烦NN拉

答案是A，我明白，但我觉得D也对啊？用NOT验证起到weaken的作用，应该也对吧？不知道怎么排除的
