Ok. I knew I was (somewhat) on track. :) Maybe the next quiz should be a little more concrete in the expected answer so there is less chance of numerous answers that could be right.

You don't need a timeline, or a MovieClip to get an enter frame event. It's very valuable to have these with regards to invalidation. Since things only redraw once per frame, you can use enter frame in tandem with other events to ensure you're only actually updating visual components once per redraw.

package { import flash.display.Sprite; import flash.events.Event;

public class TestEnterFrame extends Sprite
{
    public function TestEnterFrame()
    {
        addEventListener(Event.ENTER_FRAME, onEnterFrame);
    }

    private function onEnterFrame(event:Event):void
    {
        trace("sup");
    }
}

}
