Question Stats:

60% (02:38) correct 40% (00:52) wrong based on 2 sessions
Driver: My friends say I will one day have an accident because I drive my sports car recklessly. But I have done some research, and apparently minivans and larger sedans have very low accident rates compared to sports cars. So trading my sports car in for a minivan would lower my risk of having an accident.


The reasoning in the driver’s argument is most
vulnerable to criticism on the grounds that this
argument

(A) infers a cause from a mere correlation

(B) relies on a sample that is too narrow

(C) misinterprets evidence that a result is likely as
evidence that the result is certain

(D) mistakes a condition sufficient for bringing
about a result for a condition necessary for
doing so

(E) relies on a source that is probably not
well-informed

Logic questions are not a part of GMAT CR, but they would still give us a chance to attack GMAT crs better, I guess.
Is the OA A? My reasons for elimination is in boldface.

(A) infers a cause from a mere correlation
-> correct

(B) relies on a sample that is too narrow
We can never contradict facts. His research is given as a fact.

(C) misinterprets evidence that a result is likely as
evidence that the result is certain
This is incorrect because author still says "trading my sports car in for a minivan would lower my risk of having an accident" he doesn't say trading in would reduce the risk to ZERO.

(D) mistakes a condition sufficient for bringing
about a result for a condition necessary for
doing so
Nope, as I think there is no sufficient condition in the argument to begin with. The complete argument is based on likely hood.

(E) relies on a source that is probably not
well-informed
Again can't question his research.

Kudos if my posts helped.

Prephrase: People who drive minivans may be safe drivers. Driving a minivan doesn't make one safe by itself.

(A) infers a cause from a mere correlation Matches prephrase. Correct.

(B) relies on a sample that is too narrow Out of scope. Sample size has no role in the argument. Incorrect.

(C) misinterprets evidence that a result is likely as evidence that the result is certain No likelihood-certain relationship in argument. Incorrect.

(D) mistakes a condition sufficient for bringing about a result for a condition necessary for doing so The author doesn't say that it is necessary to drive a minivan to lower his risk of accident. Incorrect.

(E) relies on a source that is probably not well-informed Out of scope. Incorrect.

Thanks. :)

+1 A

I agree with above reasoning...

But i didnt think this much... I felt its just a correlation not a cause....
Because based on research he plans to sell Sports car ...
But there may be other reasons as well need to be considered for accidents...
( moreover accidents depends on driver not on research :lol: )
