参考答案与解析

　　Answer to Question 1

　　Choice D is best. The phrasing a divorce that occurred when they were children correctly uses the relative

　　clause that occurred to modify a divorce and includes a pronoun and verb (they were) that refer

　　unambiguously to their antecedent, men and women. Choice A incorrectly introduces the when... phrase with

　　occurring, thus illogically making divorce the grammatical referent of when a child; furthermore, the singular

　　child does not agree with the plural men and women. B replaces child with children but otherwise fails to

　　156

　　correct A's errors of structure and logic, and C corrects only the error created by occurring. Choice E includes

　　an incorrect verb tense (has occurred) and wrongly replaces when with as. Also, each was does not properly

　　refer to men and women.

　　Answer to Question 2

　　In choice C, the best answer, an area about the size of Colorado clearly describes a rough equivalence

　　between the area of Colorado and the area overseen by the companies. In A and B, the plural verb have does

　　not agree with the singular subject number. Choice A is also wordy, since that is can be deleted without loss of

　　clarity. The absence of an area in B and E impairs clarity: the phrase beginning with about must modify a noun

　　such as area that is logically equivalent to the number of acres given. In D and E up to is unidiomatic; the

　　correct expression is from x to y. In D, the size of Colorado's is unidiomatic, since of Colorado forms a

　　complete possessive.

　　Answer to Question 3

　　Because the verb phrases used to describe the bats' duties are governed by the phrase different duties such

　　as, they should each be expressed in the present participial (or "-ing") form to parallel defending and scouting.

　　Choices A, C, D, and E all violate parallelism by employing infinitives (to...) in place of participial phrases. In E

　　the singular sentinel is not consistent with residents, and the omission of and distorts the meaning of the

　　original. Only B, the best answer, preserves the sense of the original, uses the correct idiom, and observes the

　　parallelism required among and within the three main verb phrases.

　　Answer to Question 4

　　For parallelism, the linking verb is should link two infinitives: The only way to salvage ... is to process. Choice

　　A begins with an infinitive, but the plural pronouns them and they do not agree with the singular noun citrus.

　　Choices B, C, and D do not begin with an infinitive, and all present pronoun errors: the plural pronouns cannot

　　grammatically refer to citrus or fruit, nor can they refer to farmers without absurdity. The best choice, E, has

　　parallel infinitives and uses fruit to refer unambiguously to citrus. E also expresses the cause-and-effect

　　relationship between the return of warmer weather and the rotting of the fruit; A, C, and D merely describe these

　　events as contemporaneous.

　　Answer to Question 5

　　Choices A, C, and E do not state the comparison logically. The expression as old as indicates equality of age,

　　but the sentence indicates that the Brittany monuments predate the Mediterranean monuments by 2,000 years.

　　In B, the best choice, older than makes this point of comparison clear. B also correctly uses the adjective

　　supposed, rather than the adverb supposedly used in D and E, to modify the noun phrase Mediterranean

　　predecessors.
