31. The correct answer is (C). The original makes an illogical statement. It states that the seedlings
themselves will improve your chances of a rich harvest, but what the speaker means to say is that by
using seedlings, you can improve your chances of a rich harvest. (C) eliminates this ambiguity. (B)
fails to eliminate the error of the original. (D) uses the infinitive to use rather than the gerund using,
but the infinitive is not idiomatic here. And finally, (E) eliminates the only conjugated verb in the
sentence (improve becomes to improve) and reduces the sentence to a sentence fragment.
32. The correct answer is (B). The construction because . . . , so is not idiomatic English. There is no
need for the so. (B) solves this problem by eliminating the offending word. (C) does make the needed
correction, but uses the pronoun they, for which there is no referent. The that used in (E) turns the
independent clause into a noun clause and reduces the entire construction to a sentence fragment.
33. The correct answer is (D). The original suffers from an incomplete split construction. The auxil-
iary verb has needs the past participle to complete it: has been. But the word been doesn’t appear in
the sentence. As written, the sentence says that the committee has always . . . to be committed. (D)
corrects this problem by supplying the missing word. (B) fails to supply the needed word. (C) and (E)
do include been, but they destroy the effectiveness of the second element of the construction. They
read will continue committed and continues committed.
34. The correct answer is (C). The original suffers from two defects. First, it is simply not idiomatic.
(C) supplies the correct idiom. Second, you seems to refer to recipient, but you is a second-person
pronoun and cannot substitute for recipient. (C) also avoids this error. (B) corrects the second error
but not the first, whereas (D) corrects the first error but not the second. Finally, (E) is not idiomatic.
