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?

(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.

答案：

A說鹿和?

?他野生動物增加了，狼吃的別的動物增加了攻擊羊的數量應該減少，原文反而說增加了，不能解釋原文這個現象，殺。 B說1910年前，對于捕獵狼沒有法律條文存在，沒說，殺。(而且這個選項說的時間段也不對，原文要你解釋1910后的那個現象，這個選項說1910年前，無法解釋1910年后的現象) C說1910年后由于捕獵，狼不能吃其他野生動物了，不能吃野生動物了，那吃羊的可能性就提高了，留著。 D說在防御狼群攻擊的能力上，羊不如其他野生動物，羊的防御能力高低原文沒提過，除非你預測未來，認為防御能力低就會導致狼吃更多的羊，兩者之間沒有關系，殺。 E說捕獵行為把很多狼趕到邊遠山區(qū) 去了，沒提，殺。
