Two People of the Same Gender and Weight Consume the Same

Multiple Choice

Two people of the same gender and weight consume the same amount of alcohol in the same amount of time. Nevertheless, one of them sobers up substantially sooner than the other. MOST likely, this difference is due to:

A) the form in which they consumed the alcohol-beer versus wine, for instance.
B) personality; for example, Type B people usually sober up more quickly than Type A people do.
C) liver function; some people's livers metabolize alcohol faster than others' livers.
D) breathing rate; those who breathe more often can exhale the carbon-dioxide by-product of alcohol metabolism faster.
