　　Choice (D) is correct. It avoids the error of the original by properly comparing “a dog’s sense of smell” to “a human’s” sense of smell.

　　2.The correct answer is C

　　Choice (C) is correct. It avoids the error of the original by using the idiomatic “known as” instead of the awkward and unidiomatic “known to be.”

　　Choice (E) is correct. It avoids the sentence fragment error of the original by providing a main verb, “was,” to express a complete thought.

　　4.The correct answer is E

　　Choice (E) is correct. It avoids the sentence fragment error of the original by providing a main verb (“was”) to indicate the action taking place in the sentence.

　　5.The correct answer is D

　　Choice (C) is correct. It avoids the error of the original by providing a main verb (“are”) to agree with the subject of the sentence, “coffee … and bananas.”
