To determine which game Max won, let's analyze the given clues:
1. Max didn't score any points at the dart throw.
This means Max did not win the dart throw.
2. Elise correctly tossed 2 rings, but did not win the ring toss.
This implies that Elise won a different game, not the ring toss.
3. Cara won a bear for outscoring everyone in the water shoot.
This suggests that Cara won the water shoot.
4. Owen scored more than anyone at the basketball throw.
This indicates that Owen won the basketball throw.
From the given information, we know that Max didn't win the dart throw, Elise didn't win the ring toss, Cara won the water shoot, and Owen won the basketball throw.
Since there are four people and four games, each person must have won a different game. Therefore, Max must have won the remaining game, which is the ring toss.
Therefore, the answer is: B. ring toss.
