Answer:
1. Separation of powers
2. Decide if an action is constitutional
Explanation:
The United States Constitution which was created following the 1787 Constitutional Convention, had founding fathers created checks and balances by establishing "Separation of powers."
Here asides from the power of other branches of government such as Executive and Legislature, the primary power of the judicial branch over others is to "Decide if an action is constitutional."
The answer is B.
The Articles of Confederation was extremely weak due to its lack of federal power, it gave most of the authority to the states. This is discussed in the passage as it talks about how the federal/national government had no authority to raise money, etc. Thus, the answer is B, as the answer says the national government had a lack of authority to control the debt crisis.
