GWD7-27

想问一句各位大侠 这道题应该是怎么曲非的呢 ?

GWD7-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?

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.

我感觉是A取非的话,就是说first-time jobs和rework jobs的人不一样,那就weaken了“it is not because the mechanics lack competence"

恩  你的意思是不是说这个题的结论成立的条件是 not because the

mechanics lack competence.  然后正确答案的取非就是如果A 不对 那么这

个逻辑的前提不对了 就无法继续得出结论了?

恩,是的。
题目里面说不是因为技术原因而是因为他们认真不认真。如果A取非,说明本身做first time job和rework job是不一样的人,就weaken了原题的结论了。

我记得是assumption题的话,答案是选not+weaken。

恩 对呢 非常感谢, 如果是论据解释结论呢 就是not +能weaken结论的一个原因  如果是结论解释论据呢 就是not+一个能解释论据的其他原因
