　　Answer to Question 41

　　Choices A, B, C, and D contain tense errors (the use of was never applied with has been required in A, for

　　example), unidiomatic expressions (call... for considering), and uses of a pronoun (it) with no noun referent.

　　By introducing the subordinating conjunction whereby, C and D produce sentence fragments. Only E, the best

　　choice, corrects all of these problems. The predicate has never been applied refers to a span of time, from the

　　writing of the Constitution to the present, rather than to a past event (as was does), and the phrase is required

　　indicates that the provision still applies. The phrase call... to consider is idiomatic, and to do so can substitute

　　grammatically for it.

　　Answer to Question 42

　　Choice C is best because its phrasing is parallel and concise. A, D, and E begin with unnecessarily wordy

　　phrases. Choice C also uses the idiomatic expression worried about rather than worried over (as in A) or

　　worrying over (as in B); worried about is preferable when describing a condition rather than an action.

　　Whereas C uses compact and parallel noun phrases such as the removal... and the failure ... , the other

　　choices employ phrases that are wordy, awkward, or nonparallel. D is also flawed in that the plural pronoun they

　　does not agree with the singular noun administration.

　　Answer to Question 43

　　Choice A is best, for A alone makes clear that the land now known as Australia was considered the antipodes

　　before it was developed. In B, it has no logical referent, because the previous clause describes a time when

　　there was no Australia. Nor does it have a referent in C: substituting Australia for it produces a nonsensical

　　statement. D is wordy, with the unnecessary what was, and imprecise in suggesting that Australia was

　　considered the antipodes after it became Australia. E similarly distorts the original meaning, and the past perfect

　　had been is inconsistent with the past tense used to establish a time frame for the rest of the sentence.

　　Answer to Question 44

　　Choice A presents a dangling modifier. The phrase beginning the sentence has no noun that it can logically

　　modify and hence cannot fit anywhere in the sentence and make sense. Coming first, it modifies heartbeats, the

　　nearest free noun in the main clause; that is, choice A says that the heartbeats are using the Doppler ultrasound

　　device. Choice B contains the same main clause and dangling modifier, now at the end. Contrary to intent, the

　　wording in choice C suggests that physicians can use a Doppler ultrasound device after they detect fetal

　　heartbeats. In choice D the phrase using ... device should follow physician, the noun it modifies. Choice E is

　　best.

　　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

　　166

　　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.
