this q has been answered many time since that advert came on. when you post your question, it gives a choice of similar questions to see if its been answered before, and if you type in tropicana advert (as you have done) it comes up with the same question, answered four times at least before. if your question is there it means you can get the answer straight away rather than having to wait untill someone who knows can be bothered to type it in = getting your answer quicker
