Skepticism is a rhetorical method formed by flexible use of selective questions, which asks questions side by side with two or more questions, but does not require the reader to choose one of them, but makes the reader question. When the language is coherent, all doubts will be dispelled.
According to the above definition, the statement "I have traveled a lot of roads. Where have I ever seen a road full of thorns like this? I have traveled a lot of roads. Where have I seen such a rugged and difficult road?" uses skeptical rhetoric.
