Final answer:
The U.S. government and the Roman Republic are similar in that they both have forms of representative democracy, where citizens elect officials to make laws and decisions on their behalf.
Step-by-step explanation:
The government of the United States most closely resembles the government of the Roman Republic in that both utilize a system of representative democracy. In the United States, citizens elect officials such as members of Congress, the president, and other local government leaders to make decisions and legislate on their behalf, a system similar to that of the Roman Republic, where Roman citizens would elect consuls and members of the Centuriate Assembly to act in their interests. Both governments are designed to avoid tyranny of the majority by upholding the rights of the minority, and they mix different elements of governance - democratic, aristocratic, and monarchical.
