The correct answer is Landing a man on the moon will show the Soviet Union that the United States is the more powerful nation.
During the era of the Cold War, the United States and Soviet Union were battling for international political power. One of the competitions between these two dealt with technology advancements. This is known as the Space Race. This resulted in the US and Soviet Union competing for advancements in technology to show their intellectual and scientific superiority. After the United States saw the Soviet Union be the first country to successfully launch a satellite into space (Sputnik) the desire to increase America's space program increased. This culminated with the landing of an American on the moon in 1969.
