The correct answer is C. The U.S. Constitution separated powers between the judicial, legislative, and executive branches.
This distinguishing feature of the U.S. Constitution was designed to create a system of checks and balances among the three branches of government, contrasting with the Articles of Confederation, which established a much weaker national government with limited powers and no separate judicial or executive branches.
To clarify the other options:
- A is incorrect because the Articles of Confederation were the first form of government for the newly independent United States, adopted in 1781.
- B is incorrect because under the Articles of Confederation, each state had one vote in Congress regardless of size or population, which was a major point of contention leading to the Constitutional Convention.
- D is incorrect because the Articles of Confederation created a unicameral legislature but the U.S. Constitution established a bicameral legislature (the House of Representatives and the Senate) and a more robust federal government.
