The correct answer is - 2.) Communist governments under Soviet control.
The Soviet Union, just like the United States, during the Cold War period tried to have as many allies as possible in order to have stronger support and protect its interests. Eastern Europe was a region that was almost totally under the control of the Soviets, apart from Yugoslavia which was strong on its own and didn't wanted to be submissive to other country.
The Soviets sponsored Communist governments and gave them a lot of support, be it financial, propaganda, or even military one if there were problems in the country. That led to almost all of the Eastern European nations having governments that were under the influence and control of the Soviets, making them a satellite countries to the Soviet Union.

Albert Einstein is one of the most intelligent scientist all over history. He was German and a theoretical physicist acknowledged to be one of the greatest physicists of all time. He is known to develop the theory of relativity. But also made many develops on theory of quantum mechanics. Albert Einstein is one of the most intelligent scientists, other scientists like him include Isaac Newton who was a Mathematician, physicist, astronomer and greatly recognized. Albert is best known for his equation E= mc2 and has won many awards. He’s greatest contribution to the world was his theory of relativity in which described new ways of looking at time, space, matter, energy and gravity. Einstein’s work has influenced advanced modern quantum mechanics, the model of physical time, the understanding of light, solar panels, and even modern chemistry.
Problems such as his equations didn’t always work out. Things in science only works in trial and error.
Overall Albert Einstein is one of the most bravest, intelligent and modern people that invented things that helped us in learning and finding new things. He is amongst one of the most intelligent. All scientists work together and develop the world in this time.
Hope this helps!!!
