Which of the following contains the highest amount of pure alcohol?

In evaluating the amount of pure alcohol in various alcoholic beverages, it's important to understand standard drink sizes and their respective alcohol content.

All options listed contain a similar amount of pure alcohol when standardized. A standard drink in the U.S. is typically understood to contain roughly 0.6 ounces of pure alcohol.

In this context:

• A 12-ounce beer with an average alcohol by volume (ABV) of about 5% contains approximately 0.6 ounces of pure alcohol.

• A 1.5-ounce shot of distilled spirits (like whiskey or vodka) typically has an ABV of around 40%, also resulting in approximately 0.6 ounces of pure alcohol.

• A 5-ounce glass of wine with a standard ABV of about 12% also amounts to about 0.6 ounces of pure alcohol.

Since each of these beverages contains roughly the same amount of pure alcohol (0.6 ounces), the correct understanding is that all options are equivalent in terms of alcohol content. This is why the conclusion that all have the same amount of pure alcohol is correct.
