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
3.initial repairs are inadequate
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.

pleae explain...


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.

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

Answer: (A)

An assumption is something that HAS to be true for the argument to hold.

Consider the argument and how it is made:
1. Many R (complex repair jobs) have to be reworked.
2. Reworked jobs are satisfactory, but initial jobs are not.
3. Therefore, mechanic competence is not the problem, something else must be (viz. concentration rather than skill)

The conclusion of the argument is hidden in the second point. The author concludes that reworks are NOT because of a lack of skill. Now, what could make this argument fall apart? What if there are two different sets of people that carry out initial repair vs. reworks? Hmm... Indeed, if that's the case, the conclusion cannot be drawn. So, for the author to reliable draw the conclusion, this must be FALSE - the set of workers MUST be the same.

Let's see what the options suggest (see inline):

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. =>
If this is FALSE, i.e. if there IS a difference between the workers, the argument falls apart. Thus, above statement is necessary for the argument to hold and is therefore an assumption.
[B] There is no company that successfully competes with Ace Repairs for complex repair jobs. => out of scope. other companies are irrelevant.
[C] Ace Repairs' warranty is good on first-time jobs but does not cover rework jobs. => suppose it does cover rework jobs. does that have any bearing on the conclusion about worker skill? no. thus, negating the statement does not affect the argument. therefore, this is not something on which the argument DEPENDS.
[D] Ace Repairs does not in any way penalize mechanics who have worked on complex repair jobs that later had to be reworked. =>irrelevant. it doesn't matter if they do penalize the mechanics. negating this does not have any bearing on mechanic skillset.
[E] There is no category of repair jobs in which Ace Repairs invariably carries out first-time jobs satisfactorily. => there might be some such categories. a significant number does not mean "all". also, this is not related to the skill of mechanics.

The author has clearly stated in the premise that the initial repairs are inadequate not because the mechanics lack competence but because focus is more when the work is done a second time. So he definitely assumes that the mechanics who do the job the first time and those who do the rework belongs to the genre which is what is stated in "A". If you reverse the answer choice that is there is systematic difference then in the reversed form the answer choice goes against the conclusion.

A is definitely the winner, but, I think, A could have been worded better. "systematic difference in membership" does not necessarily mean difference in competence.

What if the reworks are actually done by a different group, which has the same competence as the group which did the first hand job?
In such case, negating A does not shatter the conclusion that the competence is not the reason behind the need to rework.

Thanks.

Systematic difference in membership" holistically encompasses all factors. "Systematic difference in competence" would be too specific.The very phrase "No systematic difference in membership" indicates that the two sets of people that is, the group involved in the first time work and the group doing the rework happens to be the same. But if we change the wording to "systematic difference in membership" then it might imply to two different groups which would go against the conclusion. Remember assumptions are made by the author himself and these would invariably support the conclusion,not go against the conclusion.

Hi Aryama,

Thanks for ur reply. I think there is a typo in ur response (marked in red). I understand what u said and agree that A is a 100% valid assumption.

Just let me know one thing, how is it against the conclusion that there are two groups of identical competencies. One did the first job, second the rework. Still the conclusion holds that the competency isn't the factor behind the errors, isn't it?

Thanks.
