Explanation:

First Question (Which factor fueled debate over national security in the US during 1940s - 1950s?)

• Analyze each option:
• "the fear of communist infiltration": During the 1940s - 1950s, the Cold War was ongoing, and the US had a strong fear of communist infiltration (McCarthyism era), which fueled national security debates.
• "the development of nuclear power plants": Nuclear power plant development was not a major national security debate fuel in the 1940s - 1950s (focus was on nuclear weapons and communism).
• "the slow economic growth following WW2": Post - WW2 US had economic growth (boom), not slow growth.
• "the expansion of the U.S. involvement in South Vietnam": US involvement in Vietnam escalated later (1960s), not in 1940s - 1950s.

• Analyze the ideological conflict (capitalism vs communism) between US and USSR:
• The Soviet Union was communist, the US was anti - communist. After WWII, the Korean peninsula was divided. The Soviet - controlled north became communist, and the US - influenced south became anti - communist.
• "It increased religious tensions...": Korea's division was not religious - based.
• "It intensified ethnic conflict...": The division was ideological, not ethnic (same ethnicity in Korea).
• "It created tensions over natural resources...": The division was ideological, not resource - based.

Answer:

the fear of communist infiltration
