Answer:
A referendum allows voters to vote to accept or reject a law.
Step-by-step explanation:
In the U.S since we have an indirect democracy (We vote for the people who vote for us) a referendum allows voters (usually municipal and state governments laws) to vote on certain legislation directly. Usually this has to be proposed by a lawmaker first then allowed for the direct vote. Common referendums for suburban municipalities is allowing liquor stores to be open in the town, Or as simple as recalling a mayor that has been doing their job poorly, which would trigger the mayor to be removed from their position and trigger a special election.
