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.
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.
题目分析：A说鹿和其他野生动物增加了，狼吃的别的动物增加了攻击羊的数量应该减少，原文反而说增加了，不能解释原文这个现象，杀。B说1910年前，对于捕猎狼没有法律条文存在，没说，杀。(而且这个选项说的时间段也不对，原文要你解释1910后的那个现象，这个选项说1910年前，无法解释1910年后的现象) C说1910年后由于捕猎，狼不能吃其他野生动物了，不能吃野生动物了，那吃羊的可能性就提高了，留着。D说在防御狼群攻击的能力上，羊不如其他野生动物，羊的防御能力高低原文没提过，除非你预测未来，认为防御能力低就会导致狼吃更多的羊，两者之间没有关系，不要发散。E说捕猎行为把很多狼赶到边远山区去了，没提，杀。
