OE


B, F The subordinate clauses in this sentence may make it difficult to analyze. Break the sentence apart to simplify its meaning. The sentence begins with a contrast word, "though," which means that the second half of the sentence, "some species display ..." will discuss some features that not all birds of prey share. The other parts of the sentence that mention "excellent eyesight," "excellent hunters," and "high-speed dive" are examples and elaborations that you can ignore unless you need to fine-tune your prediction. At this point, however, look for two words that mean "different." (B) unique and (F) distinctive fit well, since they both draw on the contrast between "all birds of prey" and "some species." (A) voracious means "wanting a great deal of food." This may be true of some birds of prey, but it does not follow from the contrast in the sentence. (C)fleeting, "lasting for only a little while," is incorrect because the sentence does not suggest that the characteristics are only temporary. Given the example of the peregrine falcon, (D) rapid might be tempting. This choice, however, is incorrect because it misses the contrast in the sentence and lacks a match among the other choices. (E) advantageous means "helpful" and is incorrect because it does not create a contrast: all of the characteristics cited in the sentence ("excellent eyesight," "sharp talons") could be described as helpful. Moreover, there is no match among the remaining choices.
