Explanation:
After the American colonies won their freedom from England, the thirteen colonies became thirteen states. The new states decided to work together. Their system of government was described in the Articles of Confederation. In this system, the state governments had most of the power. The Federal Government was very weak. This was very different from the government under the King of England.
The Founding Fathers thought that this system left the nation too weak. They decided to develop a new system of government. They wrote a new document called the Constitution, to replace the Articles of Confederation. The Constitution made a stronger Federal Government. It gave power to both the Federal Government and the state governments. This system is called federalism.
Here are some examples of how powers are shared between the Federal Government and state governments.

Oversee trade between states 
and with other countries

The amendment becomes part of the Constitution when it has been ratified by three-fourths (currently 38) of the states. This process has been used for ratification of every amendment to the Constitution thus far. Article V also provides for an alternative process, which has never been utilized.

challenge that early farmers did not face as a result of the change from a
nomadic lifestyle to an agricultural lifestyle could be early death caused by
disease. Because in agricultural lifestyle, the nomads are now trying to
