A more thorough explanation:

A government is a group of people who have the power to manage a political unit, organization, or state. The word "government" comes from the Latin word "gubernare," which means "to steer a ship." The government is responsible for making decisions and taking actions to ensure the proper functioning of the state. There are different forms of government, such as monarchy, oligarchy, democracy, autocracy, communism, and socialism. The constitution of a state defines the modality of designation, missions, and the powers granted to the members of the government.

The U.S. Federal Government is composed of three branches: the legislative, executive, and judicial. The legislative branch makes the laws, the executive branch carries out the laws, and the judicial branch evaluates the laws. Each branch has a power to challenge the acts of other branches, a mechanism known as the system of checks and balances. For instance, the President has the power to veto legislation adopted by Congress, and Congress can remove the President from office in exceptional circumstances. Finally, the Justices of the Supreme Court can overturn constitutional laws and are nominated by the President and confirmed by the Senate.

The French Government represents the executive power and determines and conducts the French policy, and has the administration and the armed forces under its power. The members of the French Government are appointed by both the President and the Prime Minister, the latter being the head of the French Government and dealing with the constitutional functions and powers of the Government. Under Article 20 of the French Constitution, it is the responsibility of the Government to "determine and conduct the policy of the Nation".

The Government of China is an authoritarian political system under the exclusive political leadership of the CCP (Chinese Communist Party) and is composed of the following branches: legislative, executive, military, supervisory, and judicial. The Chinese Congress is the highest state organ and controls the Constitution, the elections, and the supervision of officials and all government organs.

The Australian Government is part of the Australian Parliament and is elected at a federal election. The party with the support of most of the House of Representatives becomes the Government of Australia. The party elected remains the Government until the support of the majority is lost, or after the next federal election.

These examples illustrate how different countries have different forms of government and how the rules governing the formation of the government, its powers, and the nomination of its members depend on the state or country.
