How are people selected to serve the governing body? Please I need help

The legislative branch is made up of the two houses of Congress—the Senate and the House of Representatives. The most important duty of the legislative branch is to make laws. Laws are written, discussed and voted on in Congress.

The President is the head of the executive branch, which makes laws official. The President is elected by the entire country and serves a four-year term. The President approves and carries out laws passed by the legislative branch. He appoints or removes cabinet members and officials. He negotiates treaties, and acts as head of state and commander in chief of the armed forces.

The judicial branch oversees the court system of the U.S. Through court cases, the judicial branch explains the meaning of the Constitution and laws passed by Congress. The Supreme Court is the head of the judicial branch. Unlike a criminal court, the Supreme Court rules whether something is constitutional or unconstitutional—whether or not it is permitted under the Constitution.

Is it just free response or do you have multiple choice?
