　　Correct Answers and Explanation

　　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 rer unambiguously to their antecedent, men and women.

　　Choice A incorrectly introduces the when... phrase with occurring, thus illogically making divorce the grammatical rerent 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 correct A&aposs 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 rer 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&aposs is unidiomatic, since of Colorado forms a complete possessive.

　　Answer to Question 3

　　Because the verb phrases used to describe the bats&apos duties are governed by the phrase different duties such as, they should each be expressed in the present participial (or "-ing") form to parallel dending 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 rer to citrus or fruit, nor can they rer to farmers without absurdity.

　　The best choice, E, has parallel infinitives and uses fruit to rer unambiguously to citrus. E also expresses the cause-and-fect 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.
