24-7 确实找不到，请教拉！！

  Which of the following most logically completes the argument below?

        The expansion of large-scale farming in Africa and Asia has destroyed much of the natural vegetation on which elephants have historically depended, forcing them to turn to cultivated land to satisfy their enormous appetites. As a result, farmers have lost millions of dollars worth of crops annually. Yet even if elephant sanctuaries were created on a widespread basis to guarantee elephants sufficient natural vegetation, the raiding would likely persist, since   

(A) when elephants forage for food, they typically travel in herds.

(B) foraging elephants have been known to cause substantial damage even to plants that they do not eat.

(C) some of the land where crops have suffered extensive damage from elephants has been allowed to return to its natural state.

(D) elephants tend to prefer cultivated crops to wild vegetation as a food source

(E) elephant sanctuaries are usually created in areas that are rich in the natural vegetation on which elephants have historically depended.

我的理解是，大象因为人类expansion of farming，于是抢了cultivated lland，导致农民损失。

"raiding"是指谁的raiding？象更喜欢crops, 所以raiding will persist,又和Yet even if elephant sanctuaries were created on a widespread 。。。什么关系？

请指教. 我没转过来阿

多谢

不知不觉

本来象的居住区因为人类垦荒而面积减小,大象吃不饱,就冲到农民地里吃东东,现在即使建立大象保护区,有足够的野生食物给大象吃也没用了,因为大象吃过好东东不要吃从前的破东东了

明白啦！

I.人类侵人家象在前,所以造成…后果，所以考虑了建立保护区。

II.可象还是冲过来抢。

答案D just fill the gap.

谢谢啦！！！  

不过题目"even if elephant sanctuaries were ..."很诓人,如果是建立保护区在前

2. Foraging elephants 觅食的大象have been known to cause substantial damage even to plants that they do not eat.对raiding的理解有误.
