            INSTRUCTIONS:
               1. Check if the Left inset(margin) is set visually
                  similar to other three sides around the Radio Button
                  and CheckBox (insets set to 20 on all 4 sides).
               2. Rendering depends on OS and supported Look and Feels.
                  Verify only with those L&F where margins are visible.
               3. If the Left inset(margin) appears too small, press Fail,
                  else press Pass.
