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.

答案选B，有人可以帮我翻译一下B选项嘛？？看不太懂为什么选B><


谢谢啦！！

谢谢，了解~~那么我想问一下为什么选B呢？small mammals的食物稀少不就意味着small mammals的数量也会比较少嘛。。那不就削弱了吗？

B选项意思是，在small mammals的食物稀少的区域（in regions where food of the sort eaten by small mammals is sparse），boreal owls活动范围比在这些食物丰富的区域（in regions where such food is abundant）的活动范围要大。比较的是不同区域boreal owls的活动范围，they指代boreal bowls。
