1. the two small dogs faced each other on the sidewalk outside the store. their teeth were bared. the fur on their backs stood straight up, and low growls could be heard from each of them. just then, the store owner brought out a dog bone for each and tails began to wag. what is the central idea in this passage?

The central idea in this passage is positive reinforcement. The store owner encourages the dogs into being less aggressive and behaving better by giving them the reward of a bone if they stop. This is called positive reinforcement because it gives them a positive reward which reinforces the idea that they should behave in a certain way.
