T-3-Q40.  
Boreal owls range over a much larger area than do other owls of similar size. The reason for this behavior is that the small mammals on which owls feed are especially scarce in the forests where boreal owls live, and the relative scarcity of prey requires the owls to range more extensively to find sufficient food.
Which of the following ,if true, most helps to confirm the explanation above?
A. Some boreal owls range over an area eight times larger than the area over which any other owl of similar size ranges
B. Boreal owls range over larger areas in regions where food of the sort eaten by small mammals is sparse than they do in regions where such food is abundant.
C. After their young hatch, boreal owls must hunt more often than before in order to feed both themselves and their newly hatched young
D. Sometimes individual boreal owls hunt near a single location for many weeks at a time and do not range rather than a few hundred yards.
E. The boreal owl requires less food, relative to its weight, than is required by members of other owl species.
答案分析
A:重复表达了要解释的现象，但没有confirm the explanation - Boreal owls range over a much larger area because doing so is necessary for them to find sufficient food
B. 正确。对比Boreal owls扑食的small mammals的需要食物多少情况， Boreal owls 飞的范围大小变化。可以帮助支持Boreal owls 飞的范围大是和扑食相关。
C. hunt more often 和 Boreal owls range over a much larger area 不是一回事，无关。而且After their young hatch指的也是一个特定时段，不普遍。
D. 无关。题干问得是confirm the explanation。有些鸟有时不飞那么远，可以有各种可能，但和题干问的无关
E. 不解释，逻辑上起相反作用。
