If an average adult male has 4 drinks of beverage alcohol in one hour, the alcohol from how many drinks is left in the body after 2 hours?

Answer: B — 2 drinks

When an average adult male consumes 4 drinks of alcoholic beverages in one hour, his body will metabolize or process the alcohol over time. Generally, the body eliminates about one standard drink per hour. After two hours, the body would have processed or eliminated the alcohol from 2 drinks out of the initial 4 drinks consumed. Therefore, after 2 hours, the alcohol from 2 drinks is left in the body. This process is why option B, "2 drinks," is the correct answer.
