　　Explanation

　　1.The correct answer is E

　　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.”

　　2.The correct answer is B

　　Choice (B) is correct. It avoids the subject-verb agreement error of the original by using the singular verb “sharpens” to agree with the singular subject “Listening.”

　　3.The correct answer is C

　　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.

　　4.The correct answer is D

　　Choice (D) is correct. It avoids the awkwardness and wordiness of the original by using the idiomatic phrase “dominated by information rather than industry” to characterize the “new era” discussed in the sentence.
