87. Wolvesgenerally avoid human settlements. Forthis reason, domestic sheep, though essentially easy prey for wolves, are notusually attacked by them. In Hylantiaprior to 1910, farmers nevertheless lost considerable numbers of sheep towolves each year. Attributing this tothe large number of wolves, in 1910 the government began offering rewards tohunters for killing wolves. From 1910 to1915, large numbers of wolves were killed. Yet wolf attacks on sheep increased significantly. Whichof the following, if true, most helps to explain the increase in wolf attackson sheep? A.Populations of deer and other wild animals that wolves typically prey onincreased significantly in numbers from 1910 to 1915. B.Prior to 1910, there were no legal restrictions in Hylantia on the hunting ofwolves. C.After 1910 hunters shot and wounded a substantial number of wolves, therebygreatly diminishing these wolves' ability to prey on wild animals. D.Domestic sheep are significantly less able than most wild animals to defendthemselves against wolf attacks. E.The systematic hunting of wolves encouraged by the program drove many wolves inHylantia to migrate to remote mountain areas uninhabited by humans.
C: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。该选项提到了因果概括问题。即不是狼少=羊多,而是要根据狼的捕食能力来计算,不是每个狼都要捕食羊的。属于CQ1:因果概括问题。
这个因果怎么成立的? 因为狼的捕食能力大幅降低了,所以wolf attacks on sheep increased significantly? 这不合逻辑啊! 我怎么觉得五个选项都不对呢?
