Ethos, Pathos, and Logos are ways of encouragement used to persuade audiences.
By using Ethos, appropriate language for the audience and topic are developed, making yourself sound as if you are trustable and confident about what you are saying: I have been studying from extensive research and talking to the owner of the pet shop, that having a pet rabbit can upsurge confidence, progress overall health and teach responsibility.
By using Pathos you appeal to emotions to convince your audience: I am so sad that I do not have a pet, and having a rabbit would make me happy, it would definitely change my everyday mood. Imagine waking up happy because of seeing it every day. Do you not want me to be happy?
Lastly, by using Logos, you should use logic and reason, citing facts and statics is a good way to appeal to logos : Rabbits are great pets because they do not hut a lot of fur, are easy to entertain, are not very severe and eat cheap food.
