The statements that best describe the framework for the Constitution are:
- A system of checks and balances is designed to prevent abuse of power.
- The separation of powers ensures that no one branch has too much power.
The other two options are not accurate:
- There are three branches of government (Executive, Legislative, Judicial), not four, and they do not equally share power as suggested in the second statement.
- Powers not mentioned in the Constitution are assumed to belong to the states, not the federal government, according to the Tenth Amendment.
So the correct choices are the first and fourth statements.
