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.
Populations of deer and other wild animals that wolves typically prey on increased significantly in numbers from 1910 to 1915.
B.
Prior 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.（答案）
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. (wolves离人类的居所远了，就有机会attack domestic sheep了，那么attacks不就increase 了么？...)
E为什么不对阿？！...

E不对是因为，很多狼迁徙到偏远山区，鲜有人居的地方了。
实际上题目要解释的是，狼少了和攻击反而多了之间的关系。E说的迁徙最多解释了狼少了。
domestic sheep是农民家里养的羊，就是人在哪，羊在哪。和他们相对的是wild羊或者其他动物。

lz大概没搞清楚domestic 什么意思，这里是指“家养的”

A 無關比較
B 重複題目描述
C 因為狼獵殺野生動物的能力減弱，所以轉而攻擊人類圈養的羊群。
D 錯在比較對象錯誤。圈養的羊群比野生動物沒有抵抗野狼攻擊的能力。
E 違反題目前提 (狼遷徙到毫無人煙的地方，但狼攻擊羊群次數增加)

A.无法说明，因为其他猎物增加了，狼应该不是其他猎物
B.比较时间出错，题目要求的是1910-1915
C.答案
D.题目已经说Wolves generally avoid human settlements. For this reason, domestic sheep, though essentially easy prey for wolves, are not usually attacked by them。所以和题目条件矛盾
E.remote mountain areas uninhabited by humans意味着domestic sheep减少，无法说明。
