The correct answer is <em>"command economy"</em>, <em>"collectives"</em>, <em>"health care benefits"</em>, and <em>"price controls"</em>.
After the Second World War, the Soviet Union exercised strong political, ideological, and economic interest in the countries of Eastern Europe. Countries like Poland or Yugoslavia were governed by Communist regimes which put in practice this ideology's beliefs.
Communism proposes the creation of a strong central government who exercises a "command economy", in other words, the control of productive means, prices, investment and income of all economically related activities. The government also organized collectives, which were organized forms of distribution of the goods among the population. Finally, the government also controlled public services, such as education and healthcare.
