Answer:
All options are correct.
Explanation:
The Constitution of the United States was approved in 1787, after years of validity of the Articles of Confederation. This Constitution was sanctioned precisely for the inefficiency of the Articles in their objective of creating an efficient government.
The Constitution, specifically, had as its main objective the creation of a one-person federal executive power under the command of a president, who would represent the interest of the nation and work together (although from a superior position) with the state governments.
In turn, he proposed the creation of a bicameral legislative branch, the Congress, with a House of Representatives with proportional representation, and a Senate with equal representation between the states. The Constitution itself established that, for the count of slaves, they would be worth three fifths of a free man, giving a great representation to the southern states.
Finally, the Constitution was required, as a requirement to be approved, the insertion of a Bill of Rights with 10 amendments guaranteeing individual liberties and the rights of citizens.
