Question:

To prevent your blood alcohol concentration (BAC) from reaching the legal limit of 0.08%, you should not consume more than ____ drink(s) per hour.

A
Explaination

According to the Pennsylvania Driver's Manual, it takes a person of average weight at least one hour to process the alcohol in one standard alcoholic drink. (One standard drink equals about 12 ounces of beer, 5 ounces of wine, or 1.5 ounces of 80-proof liquor.) Therefore, to prevent your blood alcohol concentration (BAC) from reaching the legal limit of 0.08%, you should not consume more than one drink per hour. Note: This does not mean that it is safe to drive after consuming one drink per hour. Your driving abilities can be impaired even if your BAC is below the legal limit. Also, the less you weigh, the more likely you are to be affected by a given amount of alcohol. [Alcohol and Driving, Driver Factors, Chapter 3: Learning to Drive; Pennsylvania Driver's Manual]
