标题: 求助道GWD题···
GWD5-Q33:
Wolves generally avoid human settlements. For this reason, domestic sheep, though essentially easy prey for wolves, are not usually attacked by them. In Hylantia prior to 1910, farmers nevertheless lost considerable numbers of sheep to wolves each year. Attributing this to the large number for wolves, in 1910 the government began offering rewards to hunters for killing wolves. From 1910 to 1915, large numbers of wolves were killed. Yet wolf attacks on sheep increased significantly.

Which of the following, if true, most helps to explain the increase in wolf attacks on sheep?

A.

opulations of deer and other wild animals that wolves typically prey on increased significantly in numbers from 1910 to 1915.
B.

rior to 1910, there were no legal restrictions in Hylantia on the hunting of wolves.
C.   After 1910 hunters shot and wounded a substantial number of wolves, thereby greatly diminishing these wolves’ ability to prey on wild animals.
D.   Domestic sheep are significantly less able than most wild animals to defend themselves against wolf attacks.
E.   The systematic hunting of wolves encouraged by the program drove many wolves in Hylantia to migrate to remote mountain areas uninhabited by humans.
请问这个逻辑关系是怎么样的，既然已经没有捕杀野生动物的能力，不是其他能力就更少了么？

你可以这样理解，因为那些狼受伤了，没办法追上野生的猎物，但是家养的羊没有野生跑的快，而且也没有野生的警惕性高，所有容易被捕获

但是在原来不受伤了情况下照理说不是应该能够捕捉更多的羊才对么？

狼捕捉野生动物的能力下降了所以趋向于捕捉家养的羊

根据原题可知，虽然家养的羊作为驯化动物较为温顺且对于狼来讲较易捕获，但正常情况下狼并不袭击人类住地。
但因为悬赏杀狼，使得狼的数量骤减（同时作为一个整体，狼群的捕猎能力有所下降）所以狼会倾向于捕猎较为容易擒获的羊。
故C对

相比之下是C好，其他的更加莫名其妙，但是C仍旧缺乏关键逻辑。因为题目阐述的是：狼被猎杀与家羊被攻击之间的逻辑关系，而野生动物捉不到就攻击家羊之间没有逻辑必然。我觉得答案只能相比之下选C
