VMariaS [17]

Answer:

c)Fear of the atomic bomb combined with prosperity made it a time of

contrasting emotions

Explanation:

Here is a quote from my online textbook [(https://online.vitalsource.com/#/books/0077024125/cfi/6/1336!/4/2/2/[email protected]:1.57) United States History and Geography by McGrall Hill Education, on page 622]

"the country was enjoying postwar prosperity and optimism. That spirit, combined with McCarthyism, fears of Communist infiltration, and the threat of atomic attack, made the early 1950s a time of contrasts. As the 1952 election approached, Americans were looking for someone or something that would make them feel more secure."

I also took this quiz and got the answer right. Hope this helps!
