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 of 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.
情景：一般狼很少攻击羊。在1910年前的Hylantia却突然有很多羊被狼吃了。由于政府把羊的损失归因为了狼，所以政府奖励的杀狼的猎人。在1910年~1915年，确实有很多狼被杀了。但是，狼却更多的攻击羊了。
答案预估：
直接寻找解释原文现象（狼更多的攻击羊）的选项即可。
选项分析：
A选项：在1910年到1915年这段时间，鹿和其他被狼所捕食的动物的数量显著上升了。
B选项：在1910年以前，没有对Hylantia捕猎者捕狼的限制法令。
C选项：Correct. 1910年以后，猎手们弄的很多狼都受了伤，因此大幅减少了狼捕食野生动物的能力。本选项给出了“杀狼”之后可能带来的一个后果，即，狼不再有能力捕食野生动物，转而更多的捕食羊了。
D选项： 圈养的羊在抵抗狼的攻击方面要远远逊色于野生的动物。
E选项：对狼群系统的捕杀导致狼群大量的迁徙到没有人类居住的山里。
注意限定词：原文 domestic sheep（圈养的羊↑） ←反面 → 选项 wild animals（野生的动物↓）
P： 政府奖励猎人杀狼，狼变少了。
C： Yet wolf attacks on 【(domestic) sheep】 increased significantly.
但是，狼却更多的攻击（圈养的）羊了。
After 1910 hunters shot and wounded a substantial number of wolves, thereby greatly diminishing these wolves' ability to prey on【 wild animals 】
