    • checkAnswer

      public boolean checkAnswer​(java.lang.String answer)
      Checks if the user's answer matches this MultipleChoiceQuestion's expected answer. This method will consider either the letter of the choice to be correct OR the actual text of the response (both checks are case-insensitive).

      1. Do

      3. Mi
