I take English, so you're in luck!
So what you have to do is choose between "The Battle of Gettysburg" or the "I Have a Dream" speech. Persuade means to "tell your personal opinion", so you have to tell the author's opinion on his/her topic as to what he/she's telling to you; you're the reader.
Textual evidence if another way of your teacher walking up to you saying "So what paragraph is that from?"
I usually respond back writing in my paper like this: "From paragraph ______, the author's point of view (or topic) is to _______." I don't know what rhetorical devices are, but I think it means strategy to grab the reader in, maybe?
TONE is like talking to someone. As you read does the author seem to be protesting against something? Is he/she debating? etc.
EMPHASIS is the mood. Happy, sad, angry, excited, diligent, etc.
As for PACE, how fast or how slow. Just like tempo in music, how fast or slow it's played.
Use vocab, and write more than one paragraph. That should do it! :)
