Explanation

　　1.The correct answer is C

　　This sentence asks you to recognize a cause and effect relationship: a decreasing number of trees causes antelope populations to decrease. The only option in which both terms have a logical cause and effect relationship is “felling . . decrease.”

　　2.The correct answer is B

　　Choice (B) is correct. The structure of the sentence indicates that the word that fills in the blank will be explained by the part of the sentence that follows the colon. We are told that Gordon Parks adapted the screenplay for The Learning Tree "from his own novel," wrote music for the film, and directed the film. Because of his involvement in several different aspects of the film, it makes sense to describe Parks as "protean," or demonstrating great variety and diversity.

　　3.The correct answer is B

　　Only “triteness” logically completes the sentence; a poem echoing routine feelings might well be described as possessing “triteness,” in contrast to the fresh and unexpected ideas that Anne Spencer’s poems go on to express

　　4.The correct answer is E

　　The structure of this sentence indicates that the words after the colon define or directly clarify what came before. The phrase "he excels at telling stories that fascinate his listeners" serves to define the missing word. Choice (E), "raconteur," is the only word that describes someone who excels at storytelling.

　　5.The correct answer is D

　　Getting the correct answer to this question depends almost entirely on your knowing the definitions of the five words you must choose from. Which of the choices describes a judgment made “before all the facts are known?” Such a judgment, by definition, is not deliberate, and the sentence doesn't tell us whether the judgment was “harsh” or lenient, “sensible” or dumb, “fair” or unfair. “Premature” means hasty or early. It fits the blank perfectly.

　　6.The correct answer is C

　　The word "although" indicates that the two parts of the sentence contrast with each other: although most people think about the terms "bug" and "insect" one way, something else is actually true about the terms. Choice (C) logically completes the sentence, indicating that while most people think the terms are "interchangeable," the term "bug" actually refers to a "particular" group of insects.

　　7.The correct answer is B

　　It makes sense to say that the participants frequently “interrupted” the speaker while dividing into “factions,” or distinct groups, bringing them further from a “consensus,” or agreement

　　8.The correct answer is E

　　The sentence states that the pearl diver expected one kind of behavior from the buyers, but instead they behaved in a different way. Since the pearl diver expected the buyers to "compete among themselves to pay him the best price," the correct answer must be two words that make the last clause describe an opposite situation. Choice (E) is the best answer: Instead of competing to pay the pearl diver the best price, the buyers colluded (or plotted) to "swindle" him.

　　9.The correct answer is D

　　The comma indicates that the second clause of the sentence will support or restate the first clause. Only the term “enamored” reinforces the notion that doctors and their patients are “captivated,” or charmed, by “high technology” such as “computer-designed drugs and laser surgery.”

　　10.The correct answer is E

　　The sentence states that the pearl diver expected one kind of behavior from the buyers, but instead they behaved in a different way. Since the pearl diver expected the buyers to "compete among themselves to pay him the best price," the correct answer must be two words that make the last clause describe an opposite situation. Choice (E) is the best answer: Instead of competing to pay the pearl diver the best price, the buyers colluded (or plotted) to "swindle" him.
