Answer from cs61c-an (Ben Weil 16819970) for Question 1
Spatial locality is demonstrated in golf.  When it is your turn to hit, only the players who are on the same hole as you affect when you can hit the ball.  Essentially, rather than analyze the whole course, you select only those people on the same hole as you to determine their posititions on the course.
Temporal locality can be applied to baseball managers' choices of relief pitchers because usually the manager would use certain pitchers from the bullpen more frequently than others because of the better statistics of the pitcher.
