Answer to Question 45

Grammatically, the participial phrase beginning delighted must modify the subject of the main clause. Because

it is the manager who was delighted, choice C, in which the company manager appears as the subject, is the best answer. Choices A, B, D, and E create illogical statements by using it, the decision, the staff, and a raise,

respectively, as the sentence subject. Use of the passive voice in A, D, and E produces unnecessary wordiness,as does the construction the decision of the company manager was to in B.

Answer to Question 46

Choice E, the best answer, uses the adverbial phrase more quickly than to modify the verb phrase gain weight.

In A, B, and C, quicker than is incorrect because an adjective should not be used to modify a verb phrase. E is

also the only choice with consistent verb tenses. The first verb in the clauses introduced by showed that is

exercise. A and B incorrectly compound that present tense verb with a past tense verb, associated. C and D

correctly use associate, but C follows with the past tense required and D with the present perfect have

required. Both C and D incorrectly conclude with the future tense will gain.

Answer to Question 47

The use of the phrasing can heat... enough to affect in A and E is more idiomatic than the use of the

subordinate clause beginning with that in B, C, and D. Also, B produces an illogical and ungrammatical

statement by making induce parallel with the verb heat rather than with the appropriate form of the verb affect;

C lacks agreement in using the singular pronoun it to refer to the plural noun displays; and D is faulty because

induces cannot fit grammatically with any noun in the sentence. Choice A incorrectly separates the two

infinitives to affect and [to] induce with a comma when it should compound them with and, as does E, the best

choice.

Answer to Question 48

As used in choices A, B, and D, the phrases on account of and because of are unidiomatic; because, which

appears in C and E, is preferable here since because can introduce a complete subordinate clause explaining

the reason why the golden crab has not been fished extensively. B and E also produce agreement errors by

using the plural pronouns their and they to refer to the singular noun crab. Choice D, like A, fails to provide a

noun or pronoun to perform the action of living, but even with its the phrases would be more awkward and less

clear than it lives. C, which uses because and it as the singular subject of a clause, is the best choice.

Answer to Question 49

The pronoun which should be used to refer to a previously mentioned noun, not to the idea expressed in an entire

clause. In A, C, and E, which seems to refer to a vague concept involving the detection of moons, but there is no

specific noun, such as detection, to which it can refer. Also in E, the use of the phrasing the number... now known that

orbit is ungrammatical and unclear. B and D use the correct participial form, doubling, to modify the preceding

clause, but D, like A, uses known as orbiting rather than known to orbit, a phrase that is more idiomatic in context. B,

therefore, is the best answer.

Answer to Question 50

In choice A, it, the subject of the main clause, seems to refer to baby, the subject of the subordinate clause; thus, A

seems to state that the newbom baby, rather than its sense of vision, would be rated 20/500. Similarly, choices B and

A, B, and D illogically suggest that the palace and temple clusters were architects and stonemasons. For the

modification to be logical. Architects and stonemasons must immediately precede the Maya, the noun phrase it is

meant to modify. A, B, and D also use the passive verb form were built, which produces unnecessary awkwardness

and wordiness. E is awkwardly phrased and produces a sentence fragment, because the appositive noun phrase

Architects and stonemasons cannot serve as the subject of were the Maya. C, the best answer, places the Maya

immediately after its modifier and uses the active verb form built.
