　　Answer to Question 71

　　The sentence speaks of a sequence of actions in the past:

　　shareholders made their monthly payments and subsequently took turns drawing on the funds. Choice C, the best

　　answer, uses parallel past-tense verb forms to express this sequence. Choices A and B violate parallelism by using

　　taking where took is required. The wording in D results in a run-on sentence and does not specify what the members

　　took turns doing. Similarly, E does not specify what the members drew, and taking turns produces nonsense when

　　combined with the rest of the sentence.

　　Answer to Question 72

　　Choice A is faulty because an adverb such as twice cannot function as an object of the preposition by. B distorts

　　the sentence's meaning, stating that the number of engineering degrees conferred increased on more than two

　　distinct occasions. D's passive verb was ... doubled suggests without warrant that some unnamed agent

　　increased the number of engineering degrees. The past perfect tense in E, had... doubled, is inappropriate

　　unless the increase in engineering degrees is specifically being viewed as having occurred further back in the

　　past than some subsequent event. Choice C is best.

　　Answer to Question 73

　　In choices A and B, the pronoun them has no antecedent; furthermore, the (/clause in B must take should rather

　　than would. In C, necessary militarily is awkward and vague. E is wordy and garbles the meaning with

　　incorrect word order. Choice D is best: its phrasing is clear, grammatical, and idiomatic. Moreover, D is the

　　choice that most closely parallels the construction of the nonunderlined portion of the sentence. The sentence

　　states that the Admiralty and the War Office met to consider x and y, where x is the noun phrase a possible

　　Russian attempt. D provides a noun phrase, military action, that matches the structure of x more closely than

　　do the corresponding noun elements in the other choices.

　　Answer to Question 74

　　The first independent clause of the sentence describes a general situation; in A, the best choice, a second

　　independent clause clearly and grammatically presents an example of this circumstance. Choice B uses as an

　　instance ungrammatically: as an instance requires o/to form such idiomatic constructions as "She cited x as an

　　instance of y." Also, this construction cannot link infinitives such as to bend and to allow. The infinitive is again

　　incorrect in C and D. C misuses like, a comparative preposition, to introduce an example. D requires by in place

　　of to be. E, aside from being wordy and imprecise, uses the pronoun which to refer vaguely to the whole

　　preceding clause rather than to a specific noun referent.

　　Answer to Question 75

　　Choices A and B fail because the logic of the sentence demands that the verb in the main clause be wholly in the

　　future tense: if x happens, y will happen. To compound the problem, the auxiliary verbs have been in A and

　　have in B cannot properly be completed by to diminish. C, D, and E supply the correct verb form, but C and D

　　conclude with faulty as clauses that are awkward and unnecessary, because will continue describes an action

　　begun in the past. E is the best choice.

　　Answer to Question 76

　　Choices A and B are faulty because a relative clause beginning with that is needed to state Gall's hypothesis.

　　170

　　The phrase of there being, as used in A, is wordy and unidiomatic; in B, of different mental functions does

　　not convey Gall's point about those functions. Choices D and E are awkward and wordy, and both use which

　　where that would be the preferred pronoun for introducing a clause that states Gall's point. Further, the phrasing

　　of E misleadingly suggests that a distinction is being made between this hypothesis and others by Gall that are

　　not widely accepted today. Choice C is best.

　　Answer to Question 77

　　Choice A contains an agreement error: the term requires the singular it has in place of the plural they have.

　　Furthermore, widely ranging is imprecise: graphic design work does not range about widely but rather

　　comprises a wide range of activities. Choice C contains widely ranging and, like D, fails to use a verb form

　　such as laying out to define the activities, instead presenting an awkward noun phrase: corporate brochure

　　and annual report layout. The present perfect tense is used inappropriately in choices C (has signified), D

　　(have suggested... has signified), and E (have suggested) to indicate recently completed rather than ongoing

　　action. Additionally, E contains the incorrect they have and the imprecise widely ranging. Choice B is best.

　　Answer to Question 78

　　Choice A misuses which: as a relative pronoun, which should refer to a specific noun rather than to the action

　　of an entire clause. A also produces the unidiomatic and illogical construction either... and. Choice B properly

　　uses a verb phrase (resulting ...) instead of which to modify the action of the first clause and also correctly

　　completes either with or, but the verbs following either and or are not parallel: spreading must be spread to

　　match become. Choice C is flawed by the nonparallel verb spreading and the wordy phrase that begins with

　　the result of. Choice E is similarly wordy and uses and where or is required. Choice D--concise, idiomatic, and

　　parallel with the rest of the sentence--is best.

　　Answer to Question 79

　　When the verb consider is used to mean "regard" or "deem," it can be used more economically without the to

　　be of choice A; should be in choice B, as being in choice C, and as if in choice D are used unidiomatically with

　　this sense of consider, and D carries the unwarranted suggestion that Sand is somehow viewing the rural poor

　　hypothetically. Choice E, therefore, is best: each of the other choices inserts an unnecessary, unidiomatic, or

　　misleading phrase before legitimate subjects. Moreover, A and B incorrectly use these rather than them as the

　　pronoun referring to the poor. In C, portraying is not parallel with to consider. Only E has to portray, although

　　not essential, to underscores the parallelism of portray and consider.

　　Answer to Question 80

　　Choice A, the best answer, uses the simple past tense flourished to describe civilizations existing

　　simultaneously in the past. Choice B wrongly uses the past perfect had flourished; past perfect tense indicates

　　action that was completed prior to some other event described in the simple past tense: for example, "Mayan

　　civilization had ceased to exist by the time Europeans first reached the Americas." Choice C lacks as after time.

　　In choices C, D, and E, the plural pronoun those has no plural noun to which it can refer. In C, had signals the

　　incorrect past perfect; did in D and were in E are awkward and unnecessary. D and E also incorrectly use the

　　present participle flourishing where that flourished is needed.
