标题: GWD-7-Q27???

1. GWD-7-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.

为什么选A啊？实在想不明白！

A选项中，去掉no，说是两伙技术不同的人来修理和检查，怎么就削弱了呢？

是问假设的是什么,如果两批人修的是同一批机器..才能成立..如果两批人修理的机器不一样..肯定是不能成立的..因此选A.

A选项说的是修理和复查的两伙人没有明显的区别吧？
但是还是没太明白，如果两伙人技术差距很大怎么就削弱了呢……

对于这种假设题目就是取非之后看削弱
题目的意思要看懂，说的就是为什么返工之后质量要比第一次的好很多，并不是说是因为第一次的人的
技术差，而是因为第二次的精力更加集中，所以作者的假设就是两次的水平都是不相上下的。
