　　1.The correct answer is C

　　Explanation

　　The error in this sentence occurs at (C), where there is improper pronoun use. The relative pronoun “which” should not be used to refer to a person. Instead, “who” is needed.

　　2.The correct answer is E

　　Explanation

　　Choice (E) is correct. There is no error in the sentence.

　　3.The correct answer is A

　　Explanation

　　The error in this sentence occurs at (A), where awkward phrasing and an unnecessary pronoun create a comma splice. The entire phrase “It depends on” can be reduced to “Depending on.”

　　4.The correct answer is B

　　Explanation

　　The error in this sentence occurs at (B), where there is an inappropriate verb form. To match the past tense established and used elsewhere in the sentence (“Once,” “replaced”), the past-tense “became” is needed.

　　5.The correct answer is B

　　Explanation

　　The error in this sentence occurs at (B), where there is improper pronoun use. The reflexive pronoun “myself” is used incorrectly. The first-person singular pronoun “I” is needed instead so that the sentence communicates clearly that two people “got to the box office.” (“Mitzie...got to the box office” and “I got to the box office”)
