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            

  1. when elephants forage for food, they typically travel in herds.

  2. Foraging elephants have been known to cause substantial damage even to plants that they do not eat.

  3. Some of the land where crops have suffered extensive damage from elephants has been allowed to return to its natural state.

  4. Elephants tend to prefer cultivated crops to wild vegetation as a food source.

  5. Elephant sanctuaries are usually created in areas that are rich in the natural vegetation on which elephants have historically depended.

  1. when elephants forage for food, they typically travel in herds.--travle就是travel,不能认为travel的同时必定破坏crops

  2. Foraging elephants have been known to cause substantial damage even to plants that they do not eat.--结论是大象破坏农作物，和plants they do not eat无关

  3. Some of the land where crops have suffered extensive damage from elephants has been allowed to return to its natural state.--have suffered和would likely的事情无关

  4. Elephants tend to prefer cultivated crops to wild vegetation as a food source.--不管有多少sanctuaires大象都要吃庄稼，所以raid还要继续

  5. Elephant sanctuaries are usually created in areas that are rich in the natural vegetation on which elephants have historically depended.--既然已经说了是sanctuaries,就没建造地什么事了
