Got a new brain teaser. Ready?

All of them made it. They dropped the fish, the bear stopped to eat an easily caught meal, and no human was harmed. A bear, given the choice of having to go after prey that was fighting and/or running and a meal that was just waiting to be eaten would take the ready-made one. In addition, even a Grizzly bear, given a choice under normal cirstances will avoid humans. It was obvious, to me, that it was following the scent of the fish and went for that when the fish were dropped.
