Answer 1

- The Soviet Union exploded an atomic bomb. — Yes; the 1949 test ended the U.S. atomic monopoly and escalated the arms race.
- The Soviet Union launched Sputnik I. — Yes; the 1957 satellite launch kicked off the Space Race.
- Both the United States and the Soviet Union worked to develop hydrogen bombs. — Yes; thermonuclear development in the early 1950s greatly intensified the arms race.

(The Yalta Conference and the Berlin Airlift increased Cold War tensions but did not directly trigger the arms or space race in the same way.)
