Question

1. only ____ can lower blood alcohol concentration (bac) and reduce alcohols effects on a body.

drinking caffeine
eating foods high in fat
time

Explanation:

Alcohol is metabolized by the liver at a relatively constant rate. Caffeine only masks the effects of alcohol (like drowsiness) but doesn't lower BAC. Fat - rich foods can slow down alcohol absorption but not lower BAC once alcohol is in the bloodstream. Time is needed for the liver to metabolize alcohol, thus lowering BAC.

Answer:

Time
