Answer to Question 1
ANS: C
The amount of alcohol in one can of beer is equivalent to the amount in a shot of whiskey or one glass of wine. Even though the amount per volume of fluid is less in beer, the absorption of the alcohol does not change; it just may take longer to consume it. Even though red wine contains resveratrol, which may reduce cardiovascular disease, the amount is too small to have significant effects and would be offset by the amount this man consumes on a daily basis. It is not likely that someone already accustomed to consuming six cans of beer a day would be able to cut the amount in half. Moreover, daily drinking in itself may still constitute an alcohol use disorder, depending on other factors.
