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

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.
