Explanation

　　1.The correct answer is E

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

　　2.The correct answer is C

　　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.

　　3.The correct answer is B

　　The error in this sentence occurs at (B), where there is subject-verb disagreement. The singular verb “is” is needed to agree with the singular noun “the number.”

　　4.The correct answer is D

　　The error in this sentence occurs at (D), where there is illogical pronoun use. It doesn’t make sense to say that schools competed against “them” when “them” could refer to “high schools,” “schools,” or even “students.” Instead, “one another” or “each other” is needed.

　　5.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.

　　6.The correct answer is A

　　The error in this sentence occurs at (A), where there is an improper idiom. The idiom is “Encouraged by,” not “Encouraged from.”

　　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 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.

　　9.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.”

　　10.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.
