参考答案及解析：
1.The correct answer is C
Explanation
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 refined grains are bad and whole grains are good.”
2.The correct answer is A
Explanation
Choice (A) is correct. It avoids the errors of the other options by using the phrase “Its fossil record” to describe what has remained “virtually unchanged over 100 million years.”
3.The correct answer is B
Explanation
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”).
4.The correct answer is C
Explanation
Choice (C) is correct. This version of the sentence correctly compares the young athlete’s accomplishments with her coach’s accomplishments, not with her coach. In addition, it uses the plural pronoun “those” to refer to the coach’s accomplishments, which allows the noun “coach” to be correctly modified by the noun phrase “a former track star.” The possessive noun “coach’s” cannot be modified by a noun phrase.
5.The correct answer is E
Explanation
Choice (E) is correct. It avoids the error of the original by using the pronoun “that” to refer to “The language” so that one thing, “The language of the Navajo people,” is properly compared to another thing, “that [the language] of their Apache cousins.”
6.The correct answer is E
Explanation
Choice (E) is correct. It avoids the error of the original by using an appropriate idiom, “known as,” to introduce “Red Cloud,” the more familiar name of “Mahpiua Luta.”
