Give one example of a form of government that is currently being used in the world today.
Kisachek [45]

Hey there! I'm happy to help you!

One prominent form of government is the communist government, which is currently being used in countries such as China and North Korea.

Another type of government is the capitalist government, which is used by many global countries such as the United States, Russia, and South Korea.

These two governments really are a spectrum, because there can be some countries that are completely free market or that are completely communist. There are spots in between such as socialism.

I hope that this helps! Have a wonderful day!
