参考答案及解析：

1.The correct answer is D

Explanation

Choice (D) is correct. It avoids the awkwardness of the original by using the idiomatic “as … as” construction to compare “Africa” with “Asia.”

2.The correct answer is B

Explanation

Choice (B) is correct. It avoids the error of the original by replacing the awkward and imprecise “for studying by medical students” with “for medical students to study.”

3.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.”

4.The correct answer is E

Explanation

Choice (E) is correct. It avoids the faulty logic of the original by removing the unnecessary pronoun “They” and the conjunction “so” so that the size of the two types of lions is the only thing being compared.

5.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.

6.The correct answer is D

Explanation

Choice (D) is correct. It avoids the error of the original by properly comparing “a dog’s sense of smell” to “a human’s” sense of smell.
