in human intelligence. This directly supports (A) from question 35. Although (C) also does
reference writing with hands versus feet, these lines do not support (D) in question 35
because the lines clearly state an association between handiness and intelligence. And
although (D) might seem to support (C) from question 35, it does not. Choice (D) states that
the split from the nearest human ancestors took 4 to 7 million years, not the development of
handiness. The correct answer is (C).
B Cross out the word brook and use the context in this sentence to come up with your own
word or phrase that would be a good replacement. This sentence is suggesting that it’s
illogical to think that humans just one day decided to walk on two legs, so reason would not
permit such a connection. Replace brook with “permit.” Choice (B) is correct. Be careful
with (A), which is a trap answer; though it is a synonym for one meaning of brook, it is not
the meaning needed here.
C The third paragraph of this passage suggests that energy is the reason humans walk on two
limbs as opposed to other animals. This contrasts the information in the first passage, so
find the answer choice that matches this information. The author does not question putting
monkeys on treadmills, so eliminate (A). Choice (B) is also incorrect since the author never
criticizes the author of Passage 1, so get rid of it. Choice (C) is a good fit since the
paragraph offers another explanation for bipedalism. Choice (D) is out of scope, so
eliminate it. Choice (C) is the correct answer.
A Use POE to find an answer choice that is consistent with the information in the passage.
Choice (A) is a good fit since paragraph 3 states that chimpanzees are humans’ closest
living ancestor but that energy use explains why humans walk on two legs whereas
chimpanzees will sometimes walk on four. The author of Passage 2 doesn’t reject Darwin’s
theory but just says it’s incomplete, so eliminate (B). Eliminate (C) since that’s the opinion
of the author of Passage 1. Choice (D) is also incorrect since this issue is not resolved.
Choice (A) is correct.
D Choice (A) references the issues with Darwin’s theory. This appears to support (B) from
question 39. However, (B) from question 39 is too extreme; it states that the author rejects
Darwin’s theory when it is stated later in the passage that Darwin’s theory is not
necessarily wrong. Eliminate (A). Choice (B) does not relate to any of the choices from
question 39, as it clearly states that the cause of bipedalism is unknown. Eliminate (B).
Choice (C) appears to support (D) from question 39, but this line merely references a study
done in 2007; it does not state that the debate surrounding human bipedalism was solved in
that year. Eliminate (C) as well. Choice (D) clearly supports (A) from question 39, as that
line contains humans’ closest living ancestor. Choice (D) is the correct answer.
D Use POE to compare information from both passages. Choice (A) is incorrect because
neither author suggests this, so eliminate it. Eliminate (B) as well since this information is
contradicted in Passage 2. Passage 2 says nothing about grocery shopping, so eliminate (C).
This leaves (D), which is supported by both passages, as it’s the main thesis of Darwin and
the author of Passage 1. The author of Passage 2 says that this argument is incomplete, but
not necessarily incorrect. The answer is (D).
