I need to use ethos, pathos, logos

Ethos is appeal to authority; it uses examples from people who hold power or those the audience would trust, such as celebrities, politicians, etc. Pathos is appeal to emotion; examples would be the SPCA commercials, talking about starving children, anything that stirs up emotion in your audience. Logos is appeal to logic; it uses step by step explanations and common knowledge to get the point across.
