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.
It means the members of the team. Basically, the same people who worked on the first-time job and the rework.
The paragraph talks about the difference between the first-time job and the rework, which is level of concentration, not level of compentency. The only relevant choice is about who worked on those jobs. If the same group of people worked on both jobs, then their level of compentency (does not change) and concentration (increased) can easily be compared.
E. Talks about repair jobs verses first-time jobs in general, whereas the paragraph focuses on the rationale for the improvements in the specific repair jobs.
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.
