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. After getting her reward, she would then quickly swim back down to get another piece of the trash she had hidden, and so on.Kelly had essentially trained her trainers. On another 57 , Kelly caught a seagull that had flown into the pool. It was a largeseagull, so she was rewarded with a lot of fish. 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.
