It’s high time we put up a complete explanation for this one.
Question Type: Inference - Must Be True EXCEPT
Task: Read the information in the stimulus. Synthesize claims where possible. Eliminate the four answers that must be true, or pick the one answer that can’t be proven from the provided info.
(A) I always clean up "Not all A are B" claims as "Some A are not-B". So this says "Some aggression is nonviolent". We can infer this from the first claim that "violence is an EXTREME form of aggression". If violence is an extreme form, then there must be other forms of aggression that aren’t extreme, that aren’t violent.
(B) correct answer
This speaks about "the self-expression REQUIRED for survival", but we only learned something about "the self-expression SUFFICIENT for survival".
The LSAT score SUFFICIENT for getting into University of Maryland might be a very different thing from the LSAT score REQUIRED for getting into University of Maryland.
Maybe a 180 is a guarantee that UMD will accept you, whereas a 150+ is what’s REQUIRED to get in.
Furthermore, even if we forgave them from switching from "sufficient" to "required", we still have the problem that the first sentence is saying that "non-violence" is sufficient for survival. Meanwhile, (B) is saying "nonaggression" is sufficient. We have ZERO support from this information to say that something was "non-aggressive".
(C) This is a weak, thus easy-to-support, claim. We need only point to one example of a behavior that is influenced by human culture: the last sentence tells us that humans react with violence because they’re conditioned by their culture.
(D) The first sentence tells us that, under normal conditions, the self-expression that’s good enough to survive is NON-violent (it’s DISTINCT from violence). (D) just paraphrases this idea.
(E) This is a stronger, more specific version of (C). We are justified in making this more sweeping claim because the last sentence tells us that humans react with violence ONLY because they’re conditioned by THEIR culture.
I agree with previous posters who don’t love (E), because what we know is that violent behavior - when caused by unpleasant stimuli - is only a product of cultural conditioning.
But it’s possible that violent behavior in reaction to pleasant stimuli has a different cause (genetically caused chemical imbalances, for example).
However, (E) at least has SOME support. LSAT probably thought we were going to interpret the last sentence as the anthropologist saying, "Here’s when violence occurs: in certain situations, in reaction to unpleasant stimuli, and only because of cultural conditioning".
But they probably didn’t realize how sharply we LSAT test takers would be reading this claim and see the ambiguity ... it could be interpreted as "In certain situations and in reaction to unpleasant stimuli, violence is a product of cultural conditioning."
It helps to remember that the test writers frequently don’t write perfect questions, and our job is to find the best, most supported answer. As we said before, there is ZERO support for saying that something is "nonaggressive". There is at least SOME support for saying that violence is a product of culture.
