Answer:
C. They carried out mass executions.
D. They were known as mobilized killing units.
E. They were used by Germany during the invasions of Poland and the Soviet Union.
Explanation:
Einsatzgruppen was founded in 1939 as a mobile death killing unit (squad) of the Nazi German security forces during the second world war (the invasion of the Soviet Union in 1941 and Poland in 1931). The Einsatzgruppen were mainly part of the Schutzstaffel paramilitary and as such played a significant role in the mass murder of the Jewish people, Romanis, priesthood members and the intelligentsia in Poland.
Hence, the statements which best describe Einsatzgruppen are;
I. They carried out mass executions.
II. They were known as mobilized killing units.
III. They were used by Germany during the invasions of Poland and the Soviet Union.
The correct answer here would be Vladimir Lenin, leader of the Bolshevik Revolution that brought communism to power in Russia and established the Soviet Union. Lenin's "New Economic Policy" serves as an example of central planning to bring everything under the central government's control.
Karl Marx and Friedrich Engels were the philosophical founders of communist ideas back in the 19th century.
Josef Stalin was the totalitarian leader that took over the communist leadership in the USSR after Lenin's death.
I'm pretty sure (1.) is A, and I know for a fact that (3.) is D because slavery was a regular practice between quarreling tribes. I have no clue what (2.) is. Best of luck.
