Answer:
The statement that best summarizes the purpose of article IV of the Constitution is "The United States shall guarantee to every State in this Union a Republican Form of Government".
Explanation:
Article IV of the Constitution is very important since it outlines the protection of the states' form of government. "Republican" comes from "Republic" which means that supreme power and authority is "held by the people and their elected representatives" and NOT by a monarch (King or Queen). This means that no state of the Union would be under the rule of a monarch ever again. It gives the United States total sovereignty to enforce their own laws and manage their government.
