Answer:
all of the above!
Step-by-step explanation:
Researching evidence is very important so you can be reputable and back up your claims. By using appeals like ethos/pathos/logos you become more convincing, and that is very important for making a speech or writing anything persuasive, because logic and facts, emotions, and ethics rope people in to listening and understanding your point. Adding in rhetorical devices does the same. all of these answer choices are important, so the correct answer it "all of the above"
