1.The correct answer is C

　　Choice (C) is correct. It avoids the error of the original by using the idiomatic “known as” instead of the awkward and unidiomatic “known to be.”

　　2.The correct answer is D

　　Choice (D) is correct. It avoids the pronoun error of the original by using an appropriate relative pronoun (“who”) to refer to people (“heroines”).

　　3.The correct answer is E

　　Choice (E) is correct. It avoids the sentence fragment error of the original by providing a main verb (“was”) to indicate the action taking place in the sentence.

　　4.The correct answer is D

　　Choice (D) is correct. It avoids the error of the original by eliminating the relative pronoun “where,” which does not logically refer to anything else in the sentence, and by reducing the needlessly wordy “she incorporated” to “incorporating.”

　　5.The correct answer is C

　　Choice (C) is correct. It avoids the error of the original by following both parts of the “both … and” construction with the pronoun “his” (“In both his … and his … ”)
