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.

答案选D，我毫无异议。

但是选项B似乎也说得过去。既然被饲养的大象对即使它们不吃的植物依然具有极大的破坏性。那么它们对可以吃的作物就会有更大的破坏了。

        所以，就算给它们提供充足的天然食用作物，大象依然对crops的威胁很大。

各位NN 们觉得我的道理说得通吗？ 如有不正确的地方，请指出，谢谢！！！

个人推断吧?我读B就没什么感觉...感觉是你想多了.
