software engineers

Very few software engineers have left MicroFirm Corporation to seek employment else where. Thus, unless CompTech Corporation increases the salaries of its software engineers to the same level as those of MicroFirm's, these CompTech employees are likely to leave CompTech for another employer.

The flawed reasoning in the argument above is most similar to the reasoning in which of the following?

Answer choices are in image.

OA: D

Please explain in detail.

I think A and D are good contenders but D uses strong verbiage - must vs. likely - hence, it is not a case of parallel reasoning.

IMO: A.

Whats the OA?

This is a parallel reasoning question. I have never seen a parallel reasoning question in any officially released GMAT materials (parallel reasoning is staple on the LSAT). So, studying this question is likely a waset of time.

Engineers aren't leaving MicroFirm. The author argues that if CompTech doesn't increase its salaries to MicroFirm level, it is likely that CompTech's engineers will leave.

But there can be reasons other than salary for why MicroFirm engineers don't leave MicroFirm. Thus, raising CompTech's engineers' salaries may not make it any more likely that engineers won't leave.

In other words, the author assumes that, besides salaries, there aren't other causes for MicroFirm's superior engineer retainment. The author assumes away any other relevant differences between the two companies.

That's what's going on in choice A.

Robert doesn't gamble and has never been penniless. But we don't know that Robert has avoided becoming penniless because he's never gambled. And this doesn't mean that if someone else doesn't gamble they too won't ever be penniless. For, there can be other relevant differences between Robert and everyone else.

Well, the questions you've been posting seem to be designed fine. The issue with this one is it's just not a GMAT CR question type. So, I would stick to the ass., stn/wkn, inference, flaw, explain the paradox types of questions.

IMO A


D can not be OA...

B'coz arguement emphasize that IRRESPECTIVE of A (increase of salary) , B (employee leaving ) will happen

same contrast is visible in A option

BUT

D option emphasize that for B ( to be perfect) to happen, A ( diligent practice) is MANDATORY... i.e. cudn't be escaped or in other words cudn't say IRRESPECTIVE here in this context

Yep. I also endorsed choice A in my post above. @akhp: are you sure you have the right OA?

Anyways, this isn't a GMAT type question.

The OE misrepresents the premise of the stimulus. The stimulus states that "very few" engineers leave CompTech. The solution states that the "well paid" engineers "do not quit" CompTech. (That very few engineers leave CompTech does not allow us to infer that the ones leaving aren't as well paid as those who didn't leave. And for all we know all engineers at CompTech make the same money). Where the heck did "well paid" come from. And "very few" and "unlikely" don't yield conditional statements so it is very odd to say that the stimulus and choice D are parallel in flawed reasoning because mistakes in formal logic.


I had posted a big explanation for why the OE is wrong but the point is this is not a good question to study for GMAT purposes. This question (and especially the OE) looks more like a cheap knock-off of an LSAT question than it does a cheak knock-off of a GMAT question.
