Answer:
1- To try to gain control over West Berlin, the Soviet Union set up a total blockade which cut off that section of the city.
2- One place where the Cold War was "hot" and U.S. soldiers fought and died was Korea.
3- The "Iron Curtain" refers to the border between the Soviet satellite states and Western Europe.
4- The term "arms race" refers to a never-ending effort to acquire more and more weapons.
5- The purpose of the Berlin Airlift was to supply West Berlin during a blockade by the Soviet Union.
Step-by-step explanation:
1- The Berlin Blockade (June 24, 1948 - May 12, 1949) became one of the biggest crises of the Cold War, triggered when the Soviet Union interrupted rail, road and waterway access to the city of West Berlin. His goal was to force the western powers to leave, thus giving Soviet control over the whole city.
2- The Korean War was an armed conflict on the Korean Peninsula, which started on June 25, 1950 and ceased on July 27, 1953.
Prior to the formal war outbreak, a large number of military confrontations took place. The war began with North Korea attacking south of the 38th parallel. United Nations forces led by the United States entered the South Korean side, while North Korea later received help from China. The war soon passed into a stalemate. Three years later, the parties agreed on a cease-fire.
3- The Iron Curtain was a border through Europe, a dividing line between the communist "Eastern bloc" (the Soviet Union and its satellite states in Eastern Europe) and the capitalist "Western bloc" (Western countries under command of the United States of America).
4- An arms race takes place when many countries compete among themselves to develop the most powerful armed forces and the most effective weapons.
5- Between June 24, 1948 and May 12, 1949, the Soviet Union tried to put pressure on the Western allies through a blockade; obstructing roads, railways and canals, but the Potsdam Agreement guaranteed three air corridors to replenish the western sector of Berlin. This became known as the Berlin Airlift.
