单选题 A common defense of sport hunting is that it serves a vital wildlife-management function, without which countless animals would succumb to starvation and disease. This defense leads to the overly hasty conclusion that sport hunting produces a healthier population of animals.
Which of the following, if true, best supports the author's claim that sport hunting does not necessarily produce a healthier population of animals?

A、 For many economically depressed families, hunting helps keep food on the table.
B、 Wildlife species encroach on farm crops when other food supplies become scarce.
C、 Overpopulation of a species causes both strong and weak animals to suffer.
D、 Sport hunters tend to pursue the biggest and healthiest animals in a population.
E、 (E) Many people have strong moral objections to killing a creature for any reason other than self-defense.

【正确答案】 D

【答案解析】[解析] 本题问题目的非常清晰，我们可以用问题目的中的关键词：“Sports hunting”来定位选项，涉及这一关键词的只有(D)，又根据要支持的内容：关键词是否产生了一个更为healthy的动物群体，发现也只有(D)说明了这一点，所以(D)正确。(A)、(B)、(C)、(E)均不能在一个逻辑层面上对问题目的起到支持作用，所以不对。
