Answer:
Two statements are correct:
The Communists defeated the Nationalists in the Chinese civil war: The Chinese civil war was fought between the Nationalists and the Communists from 1927 to 1949. The Communist Party of China, led by Mao Zedong, defeated the Nationalist Party, led by Chiang Kai-shek, and established the People's Republic of China.
Americans became fearful and worried that communism would dominate the world: The spread of communism in Asia, notably the victory of the Chinese Communists, led many Americans to believe that communism was a global threat. This fear, known as the "Red Scare," led to intense anti-communist sentiment and actions, including McCarthyism, in which Americans were persecuted for their perceived communist sympathies.
The other two statements are not correct:
South Korea invaded North Korea in the early 1950s, sparking the Korean War: The Korean War was sparked by a surprise attack by North Korea on South Korea in June 1950. The United States intervened to support South Korea, and the war lasted until 1953.
Americans persecuted their fellow citizens because of the fear of communism: While there were instances of persecution and discrimination against individuals suspected of being communists or communist sympathizers, it is not accurate to say that Americans as a whole persecuted their fellow citizens. The fear of communism led to a climate of suspicion and distrust, however, which chilled civil liberties and free speech.
