- C and D How would you characterize someone who leaves you guessing
about his mood at every moment? A good, simple guess is “moody.” The best
answers are C and D. - A and F If you view occasional confusion as a general quality, then you risk
overlooking the opposite of confusion. A good guess would be “mental clarity.”
The best matches are A and F. - B and D The word in the blank refers to the act of “overlooking shortcomings,”
or in other words, not mentioning something. When someone fails to mention
something, that person is “ignoring” that fact. The best matches are B and D.
Notice that A doesn’t quite fit since the author doesn’t deny the shortcomings;
she simply fails to mention them. - D and E The characteristic the blank describes is “a commentary on the
serendipity” of research. If many findings are serendipitous, then the outcomes
are different from what was expected. A good prediction for the blank would
thus be “difference.” The best matches are “discordance” and “incongruity.” - C The basis of the conclusion is a correlation between sleep cycles and
expressed closeness in a relationship. From this correlation, the author
concludes that the sleep cycles cause the lack of closeness. To weaken the
argument, we want to identify a different explanation for the correlation.
Choice C does this by showing that lack of closeness leads to different sleep
cycles, rather than the reverse.
Choice A is incorrect because couples without such misaligned cycles are
irrelevant to the argument.
Choice B is incorrect because it strengthens rather than weakens the argument.
Choice D is incorrect because it is irrelevant to the argument.
Choice E is incorrect because the length of the relationship is not necessarily
relevant to the argument. - B The author structures the passage by providing an introduction to a debate and
then presenting a study that supports one side of the debate. While choice A might
be tempting, the study does not provide a resolution. The best answer is B. - A and B In line 27, the author says, “Importantly, the researchers used multiple
tools and forms of measurements to draw their conclusion,” so choice A is true.
In the third sentence, the author says, “Skulls, on the other hand, can serve as an
ideal proxy, since they are more commonly found in the wild and because they
provide a wealth of useful data to determine their species of origin.” The author
mentions this as a reason it would be beneficial to use skulls to infer whether
a species is bipedal. Since Russo and Kirk’s study strengthens the relationship
between skulls and bipedalism, we can infer that this fact makes their study
useful. There is no support for choice C.
