GWD5-Q33:

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 for 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.     Populationsof deer and other wild animals that wolves typically prey on increasedsignificantly in numbers from 1910 to 1915.

B.     Priorto 1910, there were no legal restrictions in Hylantia on the hunting of wolves.

C.     ！After 1910 hunters shot and wounded asubstantial number of wolves, thereby greatly diminishing these wolves’ abilityto prey on wild animals.

D.    Domesticsheep are significantly less able than most wild animals to defend themselvesagainst wolf attacks.

E.     Thesystematic hunting of wolves encouraged by the program drove many wolves inHylantia to migrate to remote mountain areas uninhabited by humans.

A 为什么不对？答案是c

If anything, (A) will deepen the paradox, since the other wild animals were increasing, why did these wolves prefer to the more dangerous choice?

解释paradox，“因果推理”。问题是explain paradox的关键在于有一个因，却推不出预期的果，且得到相反的果，求出logical gap.

From 1910 to 1915
“因”：hunt wolves
“果”：wolf attacks on sheep
Hunt wolves  (logical gap)  wolf attacks on sheep
CQ1 因果概况问题
CQ2 干扰因素问题

Helr的选项分析：

A.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。该选项不是“因”的一个特点，而是“因”的可能会产生的现象，不能评估因果推理。
B.在1910年以前，没有对Hylantia捕猎者捕狼的限制法令。该选项不涉及“因”，因为“因”是1910年以后的情况，也不涉及因果联系。少狼捕食少羊。
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。
D.圈养的羊在抵抗狼的攻击方面要远远逊色于野生的动物。该选项没有涉及“因”的特点，且无论羊群抵抗能力如何，都不会影响狼少=羊多这个事实，所以也不涉及因果联系。
E.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。该选项不是“因”的一个特点，而是“因”的可能会产生的现象，不能评估因果推理。





晕倒，要看清楚题目啊！不能肯定的答案一般都是干扰项，不该选。
问题要你解释的是1910到1915，很多狼被杀，但是对羊的攻击却明显增加。这是一种看起来奇怪的现象，和原来政府实施这措施的初衷不同。要你解释为何会发生这种情况，为何政府的措施引起相反的后果。其他选项易排除，因解释不了这种“但是”。CD易混。D错在没描述政府采取措施后狼的变化，也没描述羊的变化，都没变，则解释不了狼为何在政府采取政策后变得对羊的攻击却明显增加。原文要你解释的是政府采取措施后的这种奇怪现象。C说得是政府采取的措施让狼没法吃野生动物，所以只能攻击较易攻击的家养的羊。注意，解释题不需要充分，只要说出充分解释的主要信息即可。
