Think of a situation in which you are presenting your view on the same subject to two different audiences. For instance, you might be presenting your ideas on ways to stop bullying (1) to the School Board or a group of parents and (2) to a group of middle schoolers. Discuss how you would create ethos in each situation.
(You can choose a different subject to present to your audience, but your task is still the same - creation of ethos)
