Consumer advocate: There is ample evidence that the model of car one drives greatly affects the chances that one’s car will be stolen. The model of car stolen most often in our country last year, for example, was also the model stolen most often in the preceding year.
The consumer advocate’s reasoning is most vulnerable to criticism on the grounds that it
(A) fails to address adequately the possibility that the model of car that was stolen most often last year was the most common model of car in the consumer advocate’s country
(B) fails to address adequately the possibility that the age of a car also greatly affects its chances of being stolen
(C) fails to address adequately the possibility that the car model that was stolen most often last year was stolen as often as it was because it has a very high resale value
(D) presumes, without providing justification, that someone considering whether or not to steal a particular car considers only what model the car is
(E) presumes, without providing justification, that the likelihood of a car’s being stolen should override other considerations in deciding which car one should drive
EXPLANATION FROM Fox LSAT
The problem with this argument is that the consumer advocate ignores the possibility that one model of car is by far the most common, and therefore the most stolen, car. If it’s true that everyone in San Francisco drives a Prius, then it’s probable that the Prius is the most commonly stolen car,
even if Priuses are stolen less often per car than other cars. If that’s true, then buying a Prius, even if it’s the most commonly-stolen car, would actually decrease your chances of having your car stolen.
A) Yep. If the Prius is the most common car, then it might be the most commonly stolen car even if any individual Prius is no more likely, or even less likely, to be stolen than other cars. This is exactly it.
B) I suppose this answer is like, “Having a newer car increases the chance that it will be stolen, therefore having a particular model of car does not increase the chances that it will be stolen.” But that’s just silly, because there can be more than one cause for a stated effect. I mean, would it be fair to say, “Leaving the keys in the car increases the chances that it will be stolen, therefore having a Ferrari does not increase the chances that it will be stolen”? I don’t think so. Generally, it’s not a flaw in reasoning to fail to consider all other possible causes.
Of course there might be other causes. This answer is like saying, “Since you’ve ignored the possibility that eating red meat increases the incidence of cancer, you are wrong to conclude that smoking increases the incidence of cancer.” Answer A was a much stronger weakener, since it specifically attacked the purported correlation.
C) The reason why the model was stolen is irrelevant. Or, if anything, this would actually strengthen the idea that the two variables—ownership of a certain model, having one’s car stolen—are causally related because it would provide a reason to believe that one thing caused the other.
D) No, the advocate didn’t actually do this. The argument never “presumed” that there aren’t other causes of having a car stolen. Where did the argument use the word “only,” or specifically say that leaving keys in the car won’t get it stolen? It didn’t.
E) No, the advocate didn’t actually do this. This would only be the answer if the argument had said, “Therefore, you should purchase a model less likely to be stolen.”
Our answer is A.
