请教大家一道XDF小蓝的题目

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

正解是我现在能明白答案的原因，但是逻辑题中不是有一条是不可重复原文中的信息么。。题目中红色的部分既然已经能够写出并不是技能的原因，那么A选项说做第一次的worker和repair 的worker没有实际区别，那么不就是重复了文中信息了么。。。所以当时做的时候就是立马排除了

求求NN指点

红色部分在哪？

楼主答案是什么呀？你是说A是答案吗，但是A又重复文中意思了？
个人觉得没有啊，文中说，二次维修很满意，而第一次不行，不是因为缺少能力，而是因为复杂维修所需要的集中注意力（二次工作比首次能提供更多）。
所以在第一次工作的人和二次工作的人之间，并没有什么其他差别。。
并没有重复吧。。。。

为什么E选项不对？我觉得E和A差别不大啊

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. 划线部分第一部分：现象X并不是因为A
划线部分第二部分：现象X其实是因为B
这里A和B是两个彼此不想关的原因。在文中否定A的情况下，想要证明B成立，需要证明在B的情况下，A这个变量要控制一致。
说人话，就是：第一次工作做不好，并非技工能力不够。第二次才能修好，是因为第二次工作相较之下更专注。如果两次用的技工不是同一个人，那么就不能排除是否”machanics lack competence“这个因素导致了文中的问题，也就不能进一步得出conclusion。

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
