Final answer:
A precept is a general rule or principle that guides behavior. Mr. Browne's September precept is about choosing kindness over being right.
Step-by-step explanation:
A precept is a general rule or principle that can guide behavior and decision-making. In the book 'Wonder' by R.J. Palacio, Mr. Browne is a teacher who has a 'precept of the month' that he shares with his students. For example, his September precept is: 'When given the choice between being right or being kind, choose kind.' This means that in situations where one has to make a decision, it is better to prioritize kindness over winning an argument or proving oneself right.
