What was a major outcome of the Constitutional Convention?

The major outcome of the Constitutional Convention was the drafting of the Constitution. This landmark event took place in 1787, where delegates from various states gathered to address the weaknesses of the Articles of Confederation and to create a stronger federal government. The outcome was the creation of the United States Constitution, which established the framework for the national government and outlined the principles of American democracy.

While the other choices represent important aspects of the government formed after the Convention, they are not considered the primary result of that event. For instance, while the Senate was established as part of the legislative branch composed of two chambers, it was a component within the larger framework of the Constitution itself. The Bill of Rights, which comprises the first ten amendments guaranteeing individual freedoms and rights, was introduced following the ratification of the Constitution, addressing concerns that arose during the ratification process. The creation of the executive branch was indeed a component of the government structured by the Constitution, but again, it falls under the broader context of the Constitution itself rather than being an outcome on its own.

Thus, the correct answer accurately reflects that the drafting of the Constitution was the overarching outcome of the Constitutional Convention, laying the foundation for all subsequent governmental structures and rights.
