1) 3

This is a Factual Information question asking for specific information that can be found in paragraph 2. The correct answer is choice 3. The question asks specifically for “ evidence that indicates that aggression in animals is related to the hypothalamus.” Answer choices 1 and 2 are contradicted by the paragraph. Choice 2 is incorrect because, while the paragraph states that “electrical stimulation” triggers aggressive behavior in many animals, this is not “evidence” in itself, but merely support for the more general statement in choice 3 that increased hypothalamus activity, in general, is related to aggression.

2) 3

Choice 4 may be true, but it is not stated in the passage as a fact; an inference is needed to support it.
