The correct answer to this open question is the following.
Although there are no options attached, we can say the following.
Stalin failed to act quickly on promises to help the U.S., according to the agreements reached during the Yalta Conference and later in the Potsdam Conference. However, the United States also failed to do things agreed upon during the conferences. Of course, both nations have their own sides of the story. The real thing was that these series of disagreements contributed to mistrust between the nations.
During the so-called Cold War years, the Soviet Union remained in control of Czechoslovakia, East Germany, Romania, Bulgaria, Poland, and Hungary. Stalin considered these countries as a buffer in case the western allies tried to invade the Soviet Union.
The Cold War years was a time in which the United States and teh Soviet Union competed in the arms race, the space race, and in spreading/contain Communism in the world. These generated so many conflicts and wars around the world.

Answer:
In 1584, Queen Elizabeth I granted Sir Walter Raleigh a charter for the colonization of an area of North America which was to be called Virginia. Raleigh and Elizabeth intended that the venture should provide riches from the New World and a base from which to send privateers on raids against the treasure fleets of Spain. He called his new privately-funded colony, Roanoke, and founded it on an island off the coast of present-day North Carolina, where it would be relatively isolated from existing settlements in North America.
The colony was small, consisting of only 117 people, who suffered a poor relationship with the local American Indians, the Croatans, and struggled to survive in their new land. Their governor, John White, returned to England in late 1587 to secure more people and supplies; by the time he returned in 1590, the entire colony had vanished. The only trace the colonists left behind was the word “Croatoan” carved into a fence surrounding the village. Governor White never knew whether the colonists had decamped for nearby Croatoan Island (now Hatteras) or whether some disaster had befallen them all. Roanoke is still called “the Lost Colony” today.
