If Camila gets the 11-ball into the corner pocket (see arrow), then she wins the game! What is the biggest problem that might prevent Camila from winning the game?

• The 4-ball is in the left corner. There may not be enough energy transferred to the 4-ball to get it to move.

• The 5-ball and 3-ball are in front of the 11-ball. There may not be enough energy transferred to the 11-ball to get it to move.

• The 5-ball and 3-ball are in front of the 11-ball. There is no way to get energy to the 11-ball or get it to move.

• The 5-ball and 3-ball are in front of the 11-ball. There may be too much energy transferred to the 11-ball to get it to move.

What do you predict will most likely happen if Camila lightly taps the white ball, giving it just a small amount of energy?

• The white ball will transfer energy to the 5-ball. The 5-ball will move a little and then stop.

• The white ball will transfer energy to the 5-ball. Then the 5-ball will transfer energy to the 4-ball. The 4-ball will move a little and then stop.

• The white ball will transfer energy to the 5-ball. Then the 5-ball will transfer energy to the 3-ball. Then the 3-ball will transfer energy to the 11-ball. The 11-ball will move and may go into the right corner pocket.
