　　Explanation

　　1.The correct answer is B

　　Choice (B) is correct. It avoids the error of the original by replacing the awkward and wordy “suggest winged insects having possibly” with the more precise and idiomatic “suggest that winged insects may have.”

　　2.The correct answer is C

　　Choice (C) is correct. It avoids the verb tense error of the original. The past tense verb “remained” is not consistent with the present perfect tense verb “have made” and should be changed to the present tense verb “remain.”vv

　　3.The correct answer is B

　　Choice (B) is correct. It avoids the sentence fragment error of the original by providing a main verb (“began”) for the subject of the sentence, “Althea Gibson.”

　　4.The correct answer is C

　　Choice (C) is correct. It avoids the awkwardness and wordiness of the original by clearly and concisely stating what the government has failed to do—it has failed to “convince the public that rined grains are bad and whole grains are good.”

　　5.The correct answer is B

　　Choice (B) is correct. It avoids the comma-splice error of the original by using the pronoun “which” in place of the pronoun “them,” thereby turning what was originally an independent clause (“many of them are … United States”) into a relative clause that modifies “songs.”

　　6.The correct answer is B

　　Choice (B) is correct. It avoids the awkwardness of the original by using the word “Although” to introduce the comparison between the different habitats of the kiwi (“native forests” and “scrub and native grasslands”).
