so would it be # 4?

Yes.

Confederation:

The correct answer is option 4.) A loose affiliation of sovereign states that have agreed to cede some power to a central authority.

To arrive at this answer, let's break down the options and focus on their definitions:

1.) A government in which all power stems from a single central authority: This describes a unitary government, where all power is concentrated in one central authority, without any significant local or regional governments.

2.) A government that secedes from another government: This describes secession, which refers to a political entity breaking away from an existing government to form its own separate government.

3.) A government in which power is shared between a sovereign central authority and various local governments: This describes a federal government, where power is divided between a central authority and several local or regional governments. However, in the context of confederation, there is generally less central control compared to a federal system.

4.) A loose affiliation of sovereign states that have agreed to cede some power to a central authority: This defines a confederation. In a confederation, sovereign states voluntarily join together and delegate certain powers to a central authority while maintaining a significant degree of autonomy.

Thus, option 4 is the most accurate description of a confederation.
