Answer to Question 2
The text provides an example to show that in any situation, we have the power to choose our response to what is happening. We do not automatically have to react with anger toward a person who is yelling at us. We have a choice in the matter, and we can choose a different reaction. We can choose to return this person's anger with our own, or to remain calm, or to turn and walk away.
