Which of the following nations had a command economy?
the united states
britain
the soviet union
france
belgium

The correct answer is the Soviet Union

A command economy is one in which the central government has a significant role in determing the availablity/distribution of resources for a country. In this case, the Soviet Union used this system of a command economy from the early 20th century all the way up to the 1990's. This command economy allows the government to tell business what products to make, how to give distribute these resources to the citizens, etc. This system limits the economic freedom of citizens as they do not have much power to determine what products they will buy.
