Which statement best describes the organizational approach to space research after World War II in the United States?

• A. NASA and ARPA existed from the start
• B. ARPA focused on defense; NASA on science and public
• C. All space programs were centralized under one agency
• D. The government kept all space programs classified.

Answer: (B)

After World War II, the United States organized space research into two main streams: a defense-focused track under ARPA and a civilian science/public track under NASA. ARPA was built to push technologies with national security applications, prioritizing rapid, high-risk development for defense needs. NASA, created to oversee civilian space science and exploration, focused on scientific missions, public benefit, and broad dissemination of knowledge. This division reflects how the U.S. balanced advancing military capabilities with advancing science and public interests, rather than placing all space work under a single umbrella. The other options don’t fit because NASA and ARPA weren’t in place from the very start, space efforts weren’t centralized under one agency, and not all programs remained classified or were kept exclusively within defense.
