Final answer:
Under the Articles of Confederation, the federal government's Congress of Delegates was chosen by state legislatures. The judicial branch checks the powers of the executive branch by declaring presidential actions unconstitutional. A power granted to Congress under the Articles of Confederation was declaring and conducting war. A weakness of the Articles of Confederation was that Congress could not levy or collect taxes from the states.
Step-by-step explanation:
1. Under the Articles of Confederation, the federal government's Congress of Delegates was chosen by D. state legislatures. Each state legislature appointed delegates to the Congress, and regardless of its size, each state had only one vote.
2. The judicial branch checks the powers of the executive branch by C. declaring presidential actions unconstitutional. The Supreme Court, part of the judicial branch, has the power of judicial review and can declare actions taken by the president as unconstitutional.
3. A power granted to Congress under the Articles of Confederation was A. declaring and conducting war. Congress had the authority to declare war, but it lacked the power to regulate trade, tax the states, or enforce its laws.
4. A weakness of the Articles of Confederation was D. Congress could not levy or collect taxes from the states. This weakness hindered the federal government's ability to fund its operations and led to financial difficulties.
