Answer: The situation that describes a historian using rhetoric is "A historian makes a speech arguing that Great Britain had history's greatest empire."
The correct answer is C.
Step-by-step explanation:
When someone is using rhetoric, they are using persuasive speaking. They will argue their point by their language and way of speaking. They will impress an audience with just their speech and not have factual evidence of what they are arguing, they are using their own biased opinions. A person speaking in front of others who are using the art of rhetoric are doing this for their own benefit and want to change others minds without being fully truthful.
