　　Explanation

　　1.The correct answer is B

　　The error in this sentence occurs at (B), where an inappropriate verb form creates a sentence fragment. To fix this problem, the phrase “sharks, living” should be changed to “sharks live.”

　　2.The correct answer is C

　　The error in this sentence occurs at (C), where there is subject-verb disagreement. The plural verb “make” does not agree with its singular subject, “An abundant supply.”

　　3.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.

　　4.The correct answer is D

　　The error in this sentence occurs at (D), where there is a flaw in parallelism. To parallel the noun phrases previously used in the sentence (“his quest...” and “his opposition...”), “his support of” is needed in place of “he supported.”

　　5.The correct answer is D

　　The error in this sentence occurs at (D), where there is an improper idiom. What follows each part of the “both...and” construction must be grammatically parallel, but here “both” is followed by the article “the” while “and” is followed by the noun “television programmers.”

　　6.The correct answer is D

　　The error in this sentence occurs at (D), where there is an inappropriate verb form. The verb phrase “to have used” is needed to clearly express what Galileo was the first person to do.

　　7.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.”

　　8.The correct answer is E

　　There is no error in this sentence. The plural present tense verb “indicate” agrees with the plural subject “the results.” The phrase “both safer and” appropriately introduces the compound subject complement “both safer and more effective.” And the verb phrase “was…assumed” appropriately indicates an action that occurred in the past: i.e. what scientists thought before the new studies.
