Question 2

A circular plate rests at the center of a small square table. Around the table are a total of four chairs, one along each side of the square table. A person with unilateral neglect sits down in one of the chairs and eats from the plate. After he is finished, he moves to the next chair on his right and continues to eat from the plate. Assuming he never moves the plate and he continues with this procedure (moving one chair to the right and eating) how many chairs will he have to sit in to eat all the food on the plate?
