Final answer:
One ounce of hard liquor with 40% alcohol is generally equivalent to one standard drink and contains more alcohol than one ounce of beer or wine. Moderate drinking is defined based on standard drink units and the legal drinking age. The correct multiple-choice option is (c).
Step-by-step explanation:
Regarding alcohol content and standard drinks, one ounce of hard liquor that is 40% alcohol (such as 80 proof vodka) does contain more alcohol by volume than one ounce of beer or wine. However, this quantity is usually considered to be equivalent to one standard drink in the United States. This is because standard drinks contain roughly the same amount of alcohol –
for example, 12 ounces of beer at 5% alcohol by volume, 5 ounces of wine at approximately 12% alcohol by volume, and 1.5 ounces of hard liquor at 40% alcohol by volume are all seen as one standard drink. Drinking alcohol should be done in moderation, which is defined as up to one drink per day for women and up to two drinks per day for men, and only by adults of legal drinking age.
Excessive drinking can lead to alcohol intoxication, which can have serious health and legal consequences. The correct multiple-choice option is (c).
