Child: “Why?”
Parent: “Because I said so.”
3. If such actions were not illegal, then they would not be prohibited by the law.

4. They signed Jackie Chan to play the lead, because Hollywood cannot make an action movie without a big star.

    1.) Circular reasoning. Can be restated as, “he was the best candidate because he was the best candidate.”

    2.) Circular reasoning. Can be restated as, “it’s bed time because it’s time for bed.”

    3.) Circular reasoning. Can be restated as, “such actions are illegal because they are illegal.”

    4.) Not circular reasoning. Maybe? Unless it is implied that Jackie Chan is a big star because he is signed to play the lead.

    5.) Not circular reasoning. Circular reasoning would be, “I know he’s mad because I know.”

      Very good, Justin.
      But (5) is actually circular reasoning, because “mad”=”angry”.
      (5) is very similar to (2).
