Answer:
Ancient Rome and Greece were both prime examples of how a government can work. Greece used a direct democracy, meaning that every person was able to directly vote on each law or issue. The problem with this was that really that only people who lived in the capital, and were closer, were able to vote. For more populous and diverse populations and areas, a representitive democracy is used. Like it was in Ancient Rome. In this case, people elect leaders and representitives to vote and act on their behalf. This makes everyone's voice heard through their elected leader, not just the voice of those who live close enough. The founding fathers were inspired by the idea of this, because we lived in a spread out, populated and diverse area, where a representative democracy would make the most sense. Though, it was still both of these Ancient civilizations that inspired and formed governments throughout the world.
