Questions: America's first form of government, the Constitution Declaration of Independence Articles of Confederation Bill of Rights

The answer is: Articles of Confederation.

Explanation for each option:

1. Constitution: The United States Constitution is the current framework for the government of the United States, but it was not the first form of government. It was adopted in 1787, replacing the Articles of Confederation.

2. Declaration of Independence: The Declaration of Independence, adopted on July 4, 1776, was a statement declaring the thirteen American colonies' independence from British rule. It is not a form of government but rather a proclamation of sovereignty.

3. Articles of Confederation: The Articles of Confederation were the first form of government for the United States, adopted in 1777 and ratified in 1781. They established a confederation of sovereign states with a weak central government, which ultimately proved ineffective, leading to the drafting of the Constitution.

4. Bill of Rights: The Bill of Rights consists of the first ten amendments to the United States Constitution, ratified in 1791. These amendments guarantee essential rights and liberties but do not constitute a form of government on their own.

In summary, the Articles of Confederation were America's first form of government, providing a loose confederation of states with limited central authority.
