One clever dolphin, named Kelly, figured out that she would getthe same reward 54 the size of the piece of trash. Therefore, 55 she found some trash, she would hide it at thebottom of the pool under a rock. The next time the trainer came to the pool, she would 56 a piece of the trash and give it tothe trainer.

To everyone’s 58 , she kept one of the fish and used it later on to attractanother seagull, which she caught. She had learned how to “fish” for seagulls to be rewarded with more fish.
