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(shuō)鹿和?

?他野生動(dòng)物增加了，狼吃的別的動(dòng)物增加了攻擊羊的數(shù)量應(yīng)該減少，原文反而說(shuō)增加了，不能解釋原文這個(gè)現(xiàn)象，殺。 B說(shuō)1910年前，對(duì)于捕獵狼沒(méi) 有法律條文存在，沒(méi)說(shuō)，殺。(而且這個(gè)選項(xiàng)說(shuō)的時(shí)間段也不對(duì)，原文要你解釋1910后的那個(gè)現(xiàn)象，這個(gè)選項(xiàng)說(shuō)1910年前，無(wú)法解釋1910年后的現(xiàn)象) C說(shuō)1910年后由于捕獵，狼不能吃其他野生動(dòng)物了，不能吃野生動(dòng)物了，那吃羊的可能性就提高了，留著。 D說(shuō)在防御狼群攻擊的能力上，羊不如其他野生動(dòng) 物，羊的防御能力高低原文沒(méi)提過(guò)，除非你預(yù)測(cè)未來(lái)，認(rèn)為防御能力低就會(huì)導(dǎo)致狼吃更多的羊，兩者之間沒(méi)有關(guān)系，殺。 E說(shuō)捕獵行為把很多狼趕到邊遠(yuǎn)山區(qū) 去了，沒(méi)提，殺。
