标题: TTGWD7-33

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?

Populations of deer and other wild animals that wolves typically prey on increased significantly in numbers from 1910 to 1915.
Prior to 1910, there were no legal restrictions in Hylantia on the hunting of wolves.
After 1910 hunters shot and wounded a substantial number of wolves, thereby greatly diminishing these wolves’ ability to prey on wild animals.
Domestic sheep are significantly less able than most wild animals to defend themselves against wolf attacks.
The systematic hunting of wolves encouraged by the program drove many wolves in Hylantia to migrate to remote mountain areas uninhabited by humans.

Answer: E

我选的是E,参考答案是C

我翻译以下题目阿

大前提：狼怕人。所以说呢这个羊虽然很容易被捕杀但是狼很少attack them.但是1910年以前每年还是要损失很大数量的羊。政府认为是狼群过多的缘故，于是奖励捕杀。至此1910-1915狼群大规模的被捕杀。但是把这个狼攻击羊的数量却上升了，题目就是问这个事为什么how to explain我选的是E因为这个可以顺着大前提往下推

题目问的是explain the increase in wolf attacks on sheep

所以要找为啥在很多狼被捕杀的情况下，狼攻击domestic sheep的数量会增加

可能的原因是有的狼是在捕杀的过程中受伤，所以他们没有能力去攻击野生动物而只能攻击domestic sheep

E选项根本没有回答题目的问题。
