Explanation:

An event that caused a lot of concern among Americans in 1949 was the Communist takeover of China. This came as a result of the Chinese Civil War (1945-49). On October 1, 1949, Mao Zedong proclaimed the founding of the People's Republic of China. This also led to the establishment of Taiwan as a communist refuge for those who disagreed with the new regime, while the rest of China was unified under a Communist government.
