Final answer:
The system that prevents any branch of government from taking too much power is checks and balances.
Step-by-step explanation:
The system that keeps any branch of government from taking too much power is checks and balances. This system allows each branch of government to limit the powers of the other branches, ensuring a balance of power. For example, the legislative branch can pass laws, but the executive branch has the power to veto them. The judicial branch can declare laws unconstitutional, thus checking the power of the legislative and executive branches.
