Final answer:
The best description of the government framework established by the Constitution is a system of checks and balances among the three government branches to prevent any one branch from gaining excessive power.
Step-by-step explanation:
The statement that best describes the framework of government established by the Constitution is that a system of checks and balances keeps each of the three branches from having too much power. This system was set up to ensure that the legislative, executive, and judicial branches of government could regulate each other and prevent any single branch from becoming overly dominant. For example, while Congress (the legislative branch) has the power to make laws, the President (the executive branch) can veto proposed legislation, which Congress can then override with a sufficient majority. Moreover, the Supreme Court (the judicial branch) has the power to declare laws unconstitutional, further maintaining a balance among the branches.
