Consultant: A significant number of complex repair jobs carried out

Consultant: A significant number of complex repair jobs carried out by Ace Repairs have to be redone under the company's warranty, but when those repairs are redone they are invariably successful. Since we have definitely established that there is no systematic difference between the mechanics who are assigned to do the initial repairs and those who are assigned to redo unsatisfactory jobs, it is clear that inadequacies in the initial repairs cannot be attributed to the mechanics' lack of competence. Rather, it is likely that complex repairs require a level of focused attention that the company's mechanics apply consistently only to repair jobs that have been inadequately done on the first try.

In the consultant's reasoning, the two portions in boldface play which of the following roles?

A) The first is a claim that the consultant rejects as false; the second is evidence that forms the basis for that rejection.

B) The first is part of an explanation that the consultant offers for a certain finding; the second is that finding.

C) The first presents a pattern whose explanation is at issue in the reasoning; the second provides evidence to rule out one possible explanation of that pattern.

D) The first presents a pattern whose explanation is at issue in the reasoning; the second is evidence that has been used to challenge the explanation presented by the consultant.

E) The first is the position the consultant seeks to establish; the second is offered as evidence for that position.
