参考答案及解析

　　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 rerent. 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 rers 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 prerable 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 bore it was developed. In B, it has no logical rerent, because the previous clause describes a time when there was no Australia. Nor does it have a rerent 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 rer 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 prerable 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 rer 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 rer to a previously mentioned noun, not to the idea expressed in an entire clause. In A, C, and E, which seems to rer to a vague concept involving the detection of moons, but there is no specific noun, such as detection, to which it can rer. 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, therore, is the best answer.

　　Answer to Question 50

　　In choice A, it, the subject of the main clause, seems to rer 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.
