When calculating drinks for BAC, which of the following measurements is generally considered equivalent?

One shot of liquor to one glass of wine is considered equivalent in the context of calculating Blood Alcohol Content (BAC) because both typically contain a similar amount of alcohol. A standard serving of liquor (generally around 1.5 ounces of distilled spirits) contains roughly the same amount of alcohol—approximately 0.6 ounces—found in a standard glass of wine (which usually contains about 5 ounces).

This equivalence is important for understanding how different alcoholic beverages affect BAC levels because it allows individuals to make informed decisions about consumption. Recognizing that these drinks have similar alcohol content helps in assessing their impact on one's ability to drive safely or engage in other activities requiring full cognitive function and coordination.

Other choices present comparisons that do not reflect standard measurements of alcohol content. For instance, the comparison between a beer and two shots of liquor would suggest more alcohol consumption than is typical in a single beer. This discrepancy can lead to underestimating the effects of alcohol when making decisions related to driving or other activities.
