讨论GWD24-7,以前没讨论过

这道题似乎在大全里也没有,讨论汇总里也没讨论过.我觉得B选项也对,有谁能指导下,为什么不选B

GWD-24-7

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.

同问~~~~~

B说就算不吃，elephants也要破坏，那也就是说raiding会持续呀~~~~~

请NN指教~~~~

题目的逻辑链条 大象的生态环境破坏—导致大象吃农田的庄稼--农民保护庄稼就要猎杀大象；

问题的条件是：如果大象的生活环境不被破坏，结果是猎杀还是会继续，那么这个中间缺了一个链条，那就是“大象还是会吃庄稼”。

D选项的意思是说“大象天生就偏爱吃人工种植的食物”，那么，这样，就算不破坏它的生存环境，“大象还是要吃庄稼”，所以D对。

B选项是说“觅食的大象会破坏即使自己不吃的食物”，那么这个不吃的食物可能是人工种植的，也可能是野生的，所以这个联系肯定没有 D 那么直接和紧密。

不知道对不对，欢迎批判！
