For instance, the government sets prices of all goods in a command economy and they also set the production level (ie how much of a certain item to produce).
A traditional economy is based on the culture and often uses the barter method. A market economy uses currency instead of bartering, and the prices are determined by market forces (ie the people in the market). A mixed economy is a combination of command and market.
An example of a mixed economy is the United States where free market forces determine prices though there are government regulations set up to ensure the economy doesn't go south, and to ensure fair trade practices are followed.
The major events that increased polarization on the world stage from the close of world war II through 1961 had to do with the Cold War between Russia and the US--primarily proxy wars such as the Korean War.
A deadly virus emerges that can pass from human to human. I hope I helped in any sort of way, if not please not me know kindly. Good luck with your future studies. Cheers, Mabel L.
