What three items contain the same amount of alcohol?

To determine why the selected option is correct, it's crucial to understand how to calculate the amount of pure alcohol in each drink. The formula for calculating the amount of alcohol in a beverage is as follows:

1. For beer and wine: Volume (in ounces) multiplied by the alcohol by volume (ABV) percentage (expressed as a decimal).

2. For liquor: Volume (in ounces) multiplied by the proof divided by 200 (since proof is double the percentage of alcohol).

Let's break down the calculations for each item in the correct choice:

1. 12 ounce glass of 5% beer:

• Alcohol content = 12 oz * 0.05 = 0.6 oz of pure alcohol.

2. 5 ounce glass of 12% wine:

• Alcohol content = 5 oz * 0.12 = 0.6 oz of pure alcohol.

3. 1 ounce shot of 80 proof liquor:

• The proof divided by 200 gives the ABV, so 80 proof equates to 40% alcohol.

• Alcohol content = 1 oz * 0.40 = 0.4 oz of pure alcohol.

Thus, in
