(B) if they are quickly processed into juice concentrate before warmer weather returns to rot them
(C) for them to be processed quickly into juice concentrate before the fruit rots when warmer weather returns
(D) if the fruit is quickly processed into juice concentrate before they rot when warmer weather returns
(E) to have it quickly processed into juice concentrate before warmer weather returns and rots the fruit
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.
5. Carbon-14 dating reveals that the megalithic monuments in Brittany are nearly 2,000 years as old as any of their supposed Mediterranean predecessors.
(A) as old as any of their supposed
(B) older than any of their supposed
(C) as old as their supposed
(D) older than any of their supposedly
(E) as old as their supposedly
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.
6. In virtually all types of tissue in every animal species, dioxin induces the production of enzymes that are the organism's trying to metabolize, or render harmless. the chemical that is irritating it.
(A) trying to metabolize, or render harmless, the chemical that is irritating it
(B) trying that it metabolize, or render harmless, the . chemical irritant
(C) attempt to try to metabolize, or render harmless, such a chemical irritant
(D) attempt to try and metabolize, or render harmless, the chemical irritating it
(E) attempt to metabolize, or render harmless, the chemical irritant
Although an "-ing" verb such as trying can sometimes be used as a noun, the phrase the organism's trying to metabolize in A is unidiomatic because trying is used as the object of organism's. In B, trying that it metabolize is ungrammatical. The noun attempt could follow organism's; also, it would parallel the noun enzymes, and parallelism is needed here because the sentence uses the linking verb are to equate enzymes and attempt. In C and D, however, attempt to try is redundant. Choice E, which says attempt to metabolize, is best. The phrase the chemical irritant is also the most concise and precise conclusion for the sentence because it clearly refers to the dioxin mentioned earlier.
7. Dr. Hakuta's research among Hispanic children in the United States indicates that the more the children use both Spanish and English, their intellectual advantage is greater in skills underlying reading ability and nonverbal logic.
(A) their intellectual advantage is greater in skills underlying reading ability and nonverbal logic
(B) their intellectual advantage is the greater in skills underlaying reading ability and nonverbal logic
(C) the greater their intellectual advantage in skills underlying reading ability and nonverbal logic
(D) in skills that underlay reading ability and nonverbal logic, their intellectual advantage is the greater
(E) in skills underlying reading ability and nonverbal logic, the greater intellectual advantage is theirs
