　　(C)

　　(D)

　　(E)

　　Explanation

　　1.The correct answer is A

　　The error in this sentence occurs at (A), where there is noun-noun disagreement. Instead of the singular “A meteorite,” the plural “Meteorites” is needed to agree with the plural nouns found later in the sentence (“particles” and “giants”). In addition, the singular verb “shows” should be changed to “show.”

　　2.The correct answer is A

　　The error in this sentence occurs at (A), where there is an improper verb form. The use of “requires that” dictates that the subjunctive form of “to wear” is needed. The phrase “have been wearing” should simply be “wear.”

　　3.The correct answer is A

　　The error in this sentence occurs at A. The present perfect phrase “has not … been” in the dependent clause beginning with “Although” is not consistent with the past tense verb “put” in the main clause. It should be replaced with the past perfect verb phrase “had not … been” to indicate how Mrs. Griffin felt “previously” — i.e. bore she “put in extra time this year.”

　　4.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.
