Answer:
The narrator will address the reader with a serious tone.
Explanation:
If the narrator is addressing to the reader, then the narrator will use an informal tone to persuade the audience. In this case, the audience is the reader. If you're writing a persuasive essay, then you need to have a claim, reasons for that claim, evidence to back up your reasons, before finally wrapping it all up with a conclusion. In your conclusion, make sure you restate your claim.
