What did the Constitutional Convention do?

The Constitutional Convention, held in Philadelphia in 1787, was specifically convened to address the weaknesses of the Articles of Confederation and resulted in the drafting of the Constitution. Delegates from the thirteen original states came together to create a stronger federal government, balancing power between the national and state levels. The outcome of this convention was a new framework for government that established the three branches—legislative, executive, and judicial—along with a system of checks and balances to prevent any single branch from becoming too powerful. This document not only aimed to provide government structure but also included provisions for addressing various issues related to governance, rights, and the role of states.

This is why the choice indicating that the Constitutional Convention "wrote the Constitution" is correct, as it directly highlights the key achievement of the gathering. The other options refer to significant events and documents in U.S. history but were not outcomes of the Constitutional Convention itself. For instance, the Declaration of Independence was drafted prior to this convention, and the Bill of Rights was added later as the first ten amendments to the Constitution.
