You look around. Then you can see a Hershey's choclate bar floating a
little way from the surface of the isand. SUDDEN MOVEMENT!!!! You
think you saw a fast shark reaching for the candy bar. Your stomach
starts growling again. You want to grab the candy bar, but you don't
want to be lunch for the the shark. So should you grab the candy bar
before the shark eats you,or think about how the shark can
be?
