The amount of alcohol in a 1 oz. shot of 80 proof whiskey, a 5 oz. glass of wine and a 12 oz. beer are ____.

• A. All the same
• B. Different
• C. Not the same
• D. Varies by brand

Answer: (A)

The main idea here is comparing how much alcohol is in common drink servings by converting each to a standard measure of alcohol. In many safety lessons, a standard drink is about 0.6 ounces of pure alcohol. When you look at typical servings: a 5-ounce glass of wine and a 12-ounce beer are both treated as about one standard drink, so they contain roughly the same amount of alcohol. A 1-ounce shot of whiskey at 80 proof is also considered a standard drinking unit in many teaching contexts, because the goal is to compare impairment risk based on total alcohol consumed rather than the drink type. So, these common servings are treated as containing about the same amount of alcohol, which is why the correct choice is that they’re all the same.
