Step-by-step explanation:
Based on the given information, we cannot determine who consumed more alcohol between Steven and Mary.

Vodka typically has a higher alcohol content than wine, but the specific alcohol percentages of the vodka shots and wine glasses are not provided, so a direct comparison cannot be made.
