How much pure alcohol is contained in a standard drink?

The correct answer is based on the standard definition of a "standard drink" in the context of alcohol consumption. A standard drink is typically defined as containing approximately 0.6 ounces of pure alcohol. This measurement is important as it helps individuals understand alcohol intake and promotes responsible drinking.

A standard drink generally consists of:

• 12 ounces of beer (which is usually around 5% alcohol by volume)
• 5 ounces of wine (usually around 12% alcohol by volume)
• 1.5 ounces of distilled spirits (approximately 40% alcohol by volume)

All of these standard drink examples have roughly 0.6 ounces of pure alcohol, which is why this amount is crucial for assessing alcohol consumption patterns and health guidelines.

Understanding the composition of a standard drink aids in making informed decisions and understanding how different beverages can contribute to overall alcohol intake.
