You make the choices, chose two, clear, contrasting motivations - but - listen to the casting agent if they make a suggestion. They are not there to direct you, but, if they see something in what you do, they may do so a little. And remember that, even if you do not get that particular role, they may think of you for another role. You are advertising yourself, but you don't get a sale from every advert.
