New and interesting research conducted by Suleiman A. Al-Sweedan and Moath Alhaj is inspired by their observation that
though there have been many studies of the effect of high altitude on blood chemistry, there is a ______ studies of the effect
on blood chemistry of living in locations below sea level, such as the California towns of Salton City and Seeley.
quarrel about
paucity of
profusion of
verisimilitude in
Choice B is the best answer because it most logically and precisely completes the text’s discussion of studies of altitude’s
effect on blood chemistry. In this context, “paucity of” means lack of. In describing the inspiration behind Al-Sweedan and
Alhaj’s research, the text uses the word “though” to suggest a contrasting relationship between two types of studies: those
examining the effect on blood chemistry of living at a high altitude and those examining the effect on blood chemistry of
living in locations below sea level. This contrasting relationship and the text’s use of the word “many” provide context
suggesting that there are few, if any, examples of the second type of study, whereas there are numerous examples of the ﬁrst
type.
Choice A is incorrect because it wouldn’t make sense in context for there to be a “quarrel about,” or open disagreement
about, studies of the effect on blood chemistry of living in locations below sea level. The text’s use of the words “though” and
“many” suggests a contrasting relationship in terms of amount between two types of studies: those examining the effect on
blood chemistry of living at a high altitude and those examining the effect on blood chemistry of living in locations below sea
level. There’s nothing in the text to suggest that the contrast between the two types of studies involves the extent to which
researchers broadly agree or disagree about the contents of either type. Choice C is incorrect because it wouldn’t make
sense in context for there to be a “profusion of,” or great abundance of, studies of the effect on blood chemistry of living in
locations below sea level. The text’s use of the words “though” and “many” suggests a contrasting relationship in terms of
amount between two types of studies: those examining the effect on blood chemistry of living at a high altitude and those
examining the effect on blood chemistry of living in locations below sea level. Rather than logically completing this contrast,
“profusion of” would indicate that the two types of studies are similar in terms of amount, with many examples existing of
both types. Choice D is incorrect because it wouldn’t make sense in context for there to be a “verisimilitude in,” or
appearance of truth in, studies of the effect on blood chemistry of living in locations below sea level. The text’s use of the
words “though” and “many” suggests a contrasting relationship in terms of amount between two types of studies: those
examining the effect on blood chemistry of living at a high altitude and those examining the effect on blood chemistry of
