　　Answer to Question 11

　　In choice A, the introductory clause beginning Based on modifies scholars, the noun that immediately follows it:

　　in other words, A says that scholars were based on the accounts of various ancient writers. Choice B is

　　awkward and imprecise in that the referent for the pronoun it is not immediately clear. C and D are also wordy

　　and awkward, and in D By the accounts... they used is an unidiomatic and roundabout way of saying that

　　scholars used me accounts. E, the best choice, is clear and concise; it correctly uses a present participle (or

　　"-ing" verb) to introduce the modifier describing how the scholars worked.

　　Answer to Question 12

　　In A, the they after because is ambiguous; it seems illogically to refer to Formulas because they and Formulas

　　158

　　are each the grammatical subject of a clause and because the previous they refers to Formulas. In A and B, do

　　not apply to... in the same way as they do to is wordy and awkward. D, the best choice, says more concisely

　　in the same way as to. Also in B, because they refers to formulas, the introductory clause states confusedly

　　that the formulas are growing. In C and E, subject to the [same] applicability of... is wordy, awkward, and

　　imprecise; furthermore, are is preferable either before or after established big businesses to complete the

　　comparison. Finally, the referent of they is not immediately clear in E.

　　Answer to Question 13

　　In choices A and B, rates of is incorrect; when rates means "prices charged," it should be followed by for. Also

　　in B, are a force for does not accurately convey the meaning that the soaring rates are actually forcing cutbacks

　　in the present. In A and E, it is redundant to say that soaring rates have risen. Similarly, the word rises makes D

　　redundant. C, the best choice, is idiomatic and concise, and it correctly uses the progressive verb form are

　　forcing to indicate an ongoing situation.

　　Answer to Question 14

　　D, the best choice, correctly follows estimated with to be. The other choices present structures that are not

　　idiomatic when used in conjunction with estimated. Choices B, C, and E all mismatch the singular verb

　　provides with its plural subject, fragments, and in choices C and E, what was is unnecessary and wordy. In

　　choice C, the use of the verb phrase estimated that it is produces an ungrammatical sentence.

　　Answer to Question 15

　　The best choice is C because it uses the idiomatically correct expression distinguishes between x and y and

　　because it provides a structure in which the relative clause beginning which may be violent clearly modifies

　　mood swings. The other choices use distinguishes in unidiomatic constructions. Additionally, their in A is

　　intrusive and unnecessary, and the modifier of mood swings in B and D (perhaps violent) is awkward and less

　　clear than the more developed clause which may be violent.

　　Answer to Question 16

　　Choice E, the best answer, correctly uses a parallel construction to draw a logical comparison: Unlike a typical

　　automobile loan,... a lease-loan.... Choice A illogically compares an automobile loan, an inanimate thing, with

　　a lease-loan buyer, a person. In choice C, buyers makes the comparison inconsistent in number as well as

　　illogical. Choices B and D are syntactically and logically flawed because each attempts to compare the noun

　　loan and a prepositional phrase: with lease-loan buying in B and/or the lease-loan buyer in D. Choices B and

　　D are also imprecise and awkward. Finally, choice E is the only option that supplies an active verb form, does

　　not require, to parallel requires.

　　Answer to Question 17

　　Choice A is best because it correctly uses the simple past tense, the residents... at that time were, and

　　because it is the most concise. In B and D, the replacement of were with the past perfect had been needlessly

　　changes the original meaning by suggesting that the Native Americans had previously ceased to be part of the

　　widespread culture. All of the choices but A are wordy, and in C, D, and E the word people redundantly

　　describes the residents rather than the larger group to which the residents belonged. These choices are also

　　imprecise because they state that the culture, rather than people, spoke the Algonquian language. Choice E

　　displays inconsistent tenses and an error of pronoun reference, people which.

　　159

　　Answer to Question 18

　　Each choice but C contains errors of agreement. In both A and E, the singular subject (each in A, every one in E)

　　does not agree with the plural verb were, while in D, the plural subject women is mismatched with the singular

　　verb was. In B, the subject and verb agree, but the descriptive phrase placed between them creates an illogical

　　statement because each cannot be wives; each can be one of the wives, or a wife. The pronoun constructions

　　in A, B, D, and E are wordy; also, B, D, and E are very awkwardly structured and do not convey the point about

　　Hemingway's wives clearly. Choice C correctly links wives with were, eliminates the unnecessary pronouns,

　　and provides a clearer structure.

　　Answer to Question 19

　　In this sentence, the initial clause modifies the nearest noun, identifying it as the thing being compared with

　　wheat. By making protein the noun modified, choices A, C, and D illogically compare wheat with protein and

　　claim that the protein in rice has more protein than wheat does. In C and D, the comparative structure higher in

　　quality than it is in wheat absurdly suggests that rice protein contains wheat. B, the best choice, logically

　　compares wheat to rice by placing the noun rice immediately after the initial clause. B also uses that to refer to

　　protein in making the comparison between the proteins of rice and wheat. Choice E needs either that in or

　　does after wheat to make a complete and logical comparison.

　　Answer to Question 20

　　Choice A is best. The construction so abundant has capital been... that correctly and clearly expresses the

　　relationship between the abundance and the investors' response. In choice B, the repetition of so is illogical and

　　unidiomatic. Choices C, D, and E alter somewhat the intended meaning of the sentence; because of its position

　　in these statements, such functions to mean "of a kind" rather than to intensify abundant. Choice D awkwardly

　　separates has and been, and the omission of that from C and E makes those choices ungrammatical.
