The committee warned that if its suggestions were not implemented, the problems would be________and eventually rendered insoluble.

A.exacerbated
B.insurmountable
C.obliterated
D.rebutted

Answer: A

The committee mentioned in the sentence has obviously studied some specific problems, and has offered suggestions to solve them. If the committee has also warned that the non-implementation of these suggestions would eventually render the problems insoluble, it means that, according to it, these problems would become worse with the passage of time. Among the choices, exacerbated is the only word which has this meaning, and is the answer. (Insurmountable and insoluble have the same meaning: therefore, it is not logical to say that 'insurmountable problems would eventually become insoluble problems' would eventually become insoluble. So, (B) is not the appropriate choice.

The notion that cultural and biological influences _______________determine cross - cultural diversity is discredited by the fact that, in countless aspects of human existence, it is cultural programming that overwhelmingly accounts for cross-population variance.

A.Jointly
B.Completely
C.Directly
D.Equally

Answer: D

The sentence refers to the relative impacts of cultural and biological influences on cross-cultural diversity (meaning diversity in culture within the same population). The second port says categorically that the fact is that, in countless aspects of human existence, it is the cultural programming that overwhelmingly accounts for cross-population variance. Since this is contrasted with the notion hinted in the first part of the sentence (by the use of the phrase 'discredited by the fact'), that notion must be either that it is the biological influences that have such an overwhelming impact, or that the biological influences have at least as strong an impact as cultural influences over cross-cultural diversity. Among the choices, the word equally lends the second of these meanings to the given sentence, and is the answer.

A.implications - veracity
B.deductions - impudence
C.conclusions - folly
D.errors - truth

Answer: A

Correct answer: implications - veracity

The last clause settles the second blank: the student was nothing if not reliable, so Symes had no reason to doubt the truthfulness of the results. Veracity is that word, and impudence and folly are not qualities one would doubt in results at all.

Although then requires the first blank to be troubling. What alarms him is what the results might mean - their implications. Errors would fit the alarm but contradict the second half, since errors are precisely a reason to doubt the results.

A.rages

C.meanders
D.ambles

Answer: A

Correct answer: rages

Has not lost its steam and as fiercely as ever both insist on undiminished energy, so the verb must be a violent one.

Rages keeps that force. Trudges, meanders and ambles all describe slow or aimless movement, which would contradict the first half of the sentence rather than continue it.
