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.

A

rework jobs could be due to lack of competence that an employee may have, not lack of concentration. Another employee may just be better at the job

I agree its A

Argument clearly says rework is not because the mechanics lack competence
that means there is an assumption that 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.

Yes,clear A.

It reinforces that employee competence is similar for both initial and rework jobs.Thus, employee competence does not contribute to rework.

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.
Premises:
More complex repair jobs have to be reworked under warranty.
2. Reworked jobs are satisfactory
Conclusion:
Reworked jobs are done with focused concentration and reliably than first time jobs.

I ended up with Options(C) & (D), but didn't thought about option(A). Can you please explain where I went wrong? Why A is correct? Why C & D are wrong?
c) Warranty is not available for reworked jobs. So, these are done with more concentration.
d) Negation of this makes the conclusion more believable.

Hi,

horribly written argument. what is the source of the question ?
not only the passage has grammatical issues in the sentences but it is also awkwardly written.
THEREFORE is conjunctive adverb and we cannot use it the way you have done above .
Look at this to understand the correct usage .
Wrong: Andrew and Lisa are inseparable, THEREFORE, we never see them apart.
Right: Andrew and Lisa are inseparable; THEREFORE, we never see them apart.

Its a necessary assumption question.

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.Correct

B. There is no company that successfully competes with Ace Repairs for complex repair jobs.Irrelevant Information

C. Ace Repairs’ warranty is good on first-time jobs but does not cover rework jobs. .Contradict with the argument by providing opposite information

D. Ace Repairs does not in any way penalize mechanics who have worked on complex repair jobs that later had to be reworked.Outside The Scope of the Argument

E. There is no category of repair jobs in which Ace Repairs invariably carries out first-time jobs satisfactorily.Outside The Scope of the argument

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.

Type - Assumption
Boil it down - Not lack of competence , but lack of focused concentration causes initial repairs to be inadequate
Pre-Thinking - The mechanics involved in initial repair and those involved in rework have the same level of competency

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.
Correct
B. There is no company that successfully competes with Ace Repairs for complex repair jobs. Irrelevant
C. Ace Repairs’ warranty is good on first-time jobs but does not cover rework jobs. Irrelevant
D. Ace Repairs does not in any way penalize mechanics who have worked on complex repair jobs that later had to be reworked. Incorrect - even if it does penalize , this is not an assumption
E. There is no category of repair jobs in which Ace Repairs invariably carries out first-time jobs satisfactorily. Out of scope - as we have only concerned with the repair jobs that need rework

Can someone please tell me why E is incorrect.

I am continuously choosing trap answer for assumptions questions. If someone can please tell me what is the difference between A and E . They both seems like assumptions author is making.

The whole argument is about complex repair jobs and their rework.

E is a very extreme answer choice stating that there is NO repairing job that could be done first time satisfactorily.

There could be some non complex repairing jobs that are done satisfactorily first time itself. So, E is a straight out.

Remember, in assumptions, one should always avoid Extreme answer choices.

Hey abhimahna ,

Thanks for replying. That's very helpful. I think I kind of ignored the words "when initial repairs are inadequate that shows author is talking about the cases when repair are not done satisfactorily and not making assumption all of the repair are done inadequately.

Thanks for clearing it further.

Megha
