标题: GWD-7-27，讨论没提到

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. A

E. There is no category of repair jobs in which Ace
Repairs invariably carries out first-time jobs satisfactorily.
想问一下E的意思，以及是如何排除的
E是否是说“没有一种维修工作在AR第一道工序能总是使工作满意”？？
这样的话其实就跟原文的论述一样了是吧，因为有不满意所以才有第二道工序-->取非的话“有一些能满意”其实跟没取非一样，也不能削弱结论是吧
谢谢

你的理解是对的。E是无关选项。结论不需要假设所有类型的维修工作都必须返工。
