　　Explanation

　　1.The correct answer is C

　　The error in this sentence occurs at (C), where an inappropriate pronoun creates a comma splice. The relative pronoun “which” should be used instead.

　　2.The correct answer is C

　　The error in this sentence is (C): the verb "were" (which is plural) does not agree in number with the noun "quality" (which is singular). The correct sentence reads: The board reviewing the courses offered by the college found that the quality of academic programs was generally good but somewhat uneven.

　　3.The correct answer is D

　　The error in this sentence occurs at (D), where there is improper pronoun use. The plural pronoun “those” should be used to refer to the plural noun “seas.”

　　4.The correct answer is D

　　The error in this sentence occurs at (D), where there is illogical pronoun reference. There is nothing in the sentence to which the singular pronoun “it” can logically refer. The plural pronoun “they” is needed to refer to the plural noun “handcuffs.”

　　5.The correct answer is E

　　Each of the parts of the sentence underlined with A, B, C, and D is correct as written. Therefore choice (E): no error is the appropriate answer.

　　6.The correct answer is D

　　The error in this sentence occurs at (D), where there is awkward and wordy phrasing. The conjunction “and” should be either deleted or replaced by “that are.”

　　7.The correct answer is C

　　The error in this sentence is (C): the word "heavy" in the phrase "heavy veiled" should not be in the form of an adjective but in the adverbial form since it is used to modify the participle "veiled." The correct sentence reads: Maude Adams, after her spectacular triumph as the original Peter Pan, went about heavily veiled and was accessible to only a handful of intimate friends.

　　8.The correct answer is B

　　The error in this sentence occurs at (B), where there is subject-verb disagreement. The singular verb “does” does not agree with the plural noun “processes.” The plural verb “do” is needed instead.

　　9.The correct answer is C

　　The error in this sentence is (C): the pronouns "he or she" (which are both singular) do not agree with the noun "drivers" (which is plural). The correct sentence reads: All states impose severe penalties on drivers who do not stop when they are involved in accidents. Note that the verb "is" has to be changed to "are" when the subject becomes plural.
