What is the only way to reduce your blood alcohol concentration (BAC)?
- Drink coffee.
- Exercise.
- Allow your body time to get rid of the alcohol. ✓
- Take a cold shower.
Answer: C. Allow your body time to get rid of the alcohol.
The only way to reduce your BAC is to allow your body time to get rid of the alcohol; coffee, exercise, and cold showers do not lower it.
Why this is the answer
The manual says the body removes alcohol at a set rate, and its review questions ask for the only effective method to reduce BAC. It states plainly that coffee, exercise, and cold showers cannot reduce BAC or the effects of alcohol; they may keep you awake but do not make you sober. The only effective method it gives is not drinking over a period of time, which means giving your body time to clear the alcohol instead of trying a quick fix. That matches allowing your body time.
Why the other answers are wrong
- A. Drink coffee. — Coffee cannot reduce BAC according to the manual; it can help you stay awake but does not sober you up.
- B. Exercise. — Exercise cannot reduce BAC; the manual lists it with quick fixes that do not change BAC.
- D. Take a cold shower. — A cold shower cannot reduce BAC or the effects of alcohol, even if it helps you feel more awake.
Remember it
Only time clears alcohol; coffee, exercise, and cold showers just help you stay awake.
