On the Galápagos Islands, the amazing tool-using "woodpecker finch" can modify twigs to pry out grubs. Because there are no true woodpeckers on the Galápagos Islands, this behavior allows this finch to exploit an untapped food source. However, not all members of this species exhibit this behavior, which is probably learned from watching other finches. Therefore,

A. there must be a great advantage to reaching this food source for this learned behavior to be repeated by most descendants of each generation. B. young chicks isolated at hatching will not know how to do this. C. it is probably not "hardwired" in the brain as a behavior passed on genetically. D. All of the choices are correct.
