Drinking coffee after drinking alcohol:
- Decreases blood alcohol content
- Cancels the effect of the alcohol
- Has no effect on blood alcohol content ✓
- Increases blood alcohol content
Answer: C. Has no effect on blood alcohol content
Drinking coffee after drinking alcohol has no effect on blood alcohol content.
Why this is the answer
The manual says coffee, exercise, and cold showers cannot reduce your BAC and cannot change the effects of alcohol. Coffee may help you stay awake, but it cannot change your BAC or make you sober. The only effective way to reduce BAC described there is to stop drinking over a period of time. So coffee does not lower, cancel, or raise BAC; it simply has no effect on it.
Why the other answers are wrong
- A. Decreases blood alcohol content — Coffee cannot decrease blood alcohol content, because the manual says it cannot reduce your BAC.
- B. Cancels the effect of the alcohol — Coffee does not cancel the effect of alcohol; it may help you stay awake, but it cannot make you sober.
- D. Increases blood alcohol content — Coffee does not increase blood alcohol content, because the manual says it cannot change your BAC at all.
Remember it
Coffee wakes you up, but it does not sober you up.
