　　Explanation

　　1.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.

　　2.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.”

　　3.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.”

　　4.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.

　　5.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.”

　　6.The correct answer is A

　　The error in this sentence is (A): the phrase "protest on" is not idiomatic in standard written English. The verb "protest" takes the preposition "against." The correct sentence reads: Originally a protest against conventional painting, the Pre-Raphaelite movement exerted great influence on the art of its time.
