GWD28-38
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?

A. 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.
B. There is no company that successfully competes with Ace Repairs for complex repair jobs.
C. Ace Repairs’ warranty is good on first-time jobs but does not cover rework jobs.
D. Ace Repairs does not in any way penalize mechanics who have worked on complex repair jobs that later had to be reworked.
E. There is no category of repair jobs in which Ace Repairs invariably carries out first-time jobs satisfactorily.

答案是A,想請問D要如何刪除?是因為處罰怪怪的嗎?
我的想法是若AR對在重修技工方面沒有處罰或不利,所以導出重修比第一次好.

題目的結論是認為工作的專注與否造成了成果的差異，而非由技巧的不同所造成，因此答案A跟結論有明確的關連。

答案D則看不出跟結論有什麼關係，建議找跟結論有密切關連的選項。
