Answer:
The democratic concept of the referendum is similar to the democratic process of ancient Greece in that both involve direct participation by the people in the decision-making process. In ancient Greece, citizens would gather in the public assembly to discuss and vote on important matters facing the city-state. In a referendum, citizens are given the opportunity to vote directly on a specific issue or proposal, rather than relying on representatives to make decisions on their behalf. In both cases, the goal is to ensure that the will of the people is taken into account when making important decisions that affect the community.
