Step-by-step explanation:
The time period or event that the document describes is b) The Cold War. This period began after World War II and lasted until the collapse of the Soviet Union in 1991. It was characterized by the division of the world into two major blocs - the United States and its allies against the Soviet Union and its satellite states. The Cold War era was defined by several key aspects, including the arms race, space exploration known as the Space Race, proxy wars, and the ideological clash between capitalism and communism. A significant feature of this time was the lack of direct military confrontation, known as a "hot war," between the two superpowers. Instead, the conflict was expressed through political maneuvering, espionage, economic pressures, and competitions for technological supremacy, such as missile development and achievements in space travel.
