Question

A study in New York City showed that more than 50 percent of retailers sold alcohol to minors.

Which policy most likely helped reduce the incidence of retailers selling alcohol to minors?

increasing the price of beer
reducing excise tax on soda
raising the legal drinking age
using compliance checks

Answer 1

Using compliance checks.

Explanation: Undercover compliance checks (decoy purchases and enforcement/penalties) directly deter and catch retailers who sell to minors, reducing the incidence much more effectively than unrelated tax changes or raising the drinking age alone.
