Fact #1: The tournament begins with 32 teams
Fact #2: With each game played, 1 team leaves
Fact #3: The tournament continues until only 1 team remains.

So, if there are 31 games, there will be 31 teams that leave the tournament, leaving only 1 team (the winning team).

Answer: D

In the first round, since 32 teams are playing, there will be 32/2 = 16 games played. In the second round, there will be 16/2 = 8 games played. In the third round, there will be 8/2 = 4 games played. In the fourth round, there will be 4/2 = 2 games played. In the fifth or final round, there is 1 game played. Thus, the total number of games is:

16 + 8 + 4 + 2 + 1 = 31

Answer: D
