Brief Explanations:

The Twelfth Amendment refined the Electoral College process. It was adopted in 1804. Before this amendment, the Electoral College had a system where each elector cast two votes for president (without distinguishing between president and vice - president). The Twelfth Amendment changed this by having electors cast separate votes for president and vice - president. The Thirteenth Amendment abolished slavery. The Tenth Amendment is about the powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people. The Eleventh Amendment dealt with sovereign immunity of states.
