Final answer:
A standard drink in the United States typically contains 14 grams of pure alcohol, which is equivalent to 1) 1.5 fluid ounces of spirits. The other volumes listed exceed or do not meet the standard drink measure, with the answer being the 1.5 fluid ounces of spirits option.
Step-by-step explanation:
In the context of alcohol consumption and its measurement, a standard drink refers to a drink that contains a fixed amount of pure alcohol. This amount is typically defined in terms of fluid ounces and varies according to the type of alcoholic beverage due to different alcohol content levels. In the United States, a standard drink is understood to contain about 14 grams of pure alcohol, which is equivalent to:
- 1.5 fluid ounces of spirits (around 40% alcohol by volume)
- 5 fluid ounces of wine (around 12% alcohol by volume)
- 12 fluid ounces of regular beer (around 5% alcohol by volume)
- 8-9 fluid ounces of malt liquor (around 7% alcohol by volume)
Therefore, the list provided includes options that do not match the U.S. standard drink measures. Among the options provided, 1.5 fluid ounces of spirits is equivalent to a standard drink. The other options list quantities of alcohol that are either greater or less than the typical standard drink volume in the U.S. The answer is option 1.
