The option which is not a characteristic of dialect in this passage from "The Notorious Jumping Frog of Calaveras County" by Mark Twain is sarcasm.There is nothing sarcastic in this excerpt - a man is just weighing a frog in order to see whether it can compete with his cats. No sarcasm is involved here. However, incorrect spelling and grammar are obvious, and there are a couple of examples of slang as well.
