### Instruction: Tell me whether these terms are related to tennis, hockey, or basketball: alley oop, snap shot, serve, backhand shot, lay up, drop shot.
### Response: Alley-oop and layup are basketball terms. An alley-oop is when one player throws the ball to another player who jumps to catch the ball and dunks it mid-air. Layup is made by leaping from below, laying the ball up near the basket, and using one hand to bounce it off the glass and into the hoop.

Snap shot is a hockey term. The snap shot combines the main advantages of the wrist shot (shot accuracy and quick delivery) and slap shot (puck speed).

Serve and drop shot are tennis terms. To complete a serve, a player will hit the ball with a racquet so it will fall into the diagonally opposite service box without being stopped by the net. A drop shot is when a player hits the ball over the net and the ball lands close to the net and bounces low, often hit with some lob and significant backspin.

Backhand shot is a term in tennis as well as hockey used to describe hitting a tennis ball or hockey puck on the backhand side of the racquet or hockey stick.
