Final answer:
The tiny Communist Party emerged in America due to various factors, including the call for international revolution, the Great Depression, racial discrimination, the Red Scare, and bomb threats.
Step-by-step explanation:
The emergence of the Communist Party in America can be attributed to several factors. In the early 20th century, the call for international revolution by the Communist International led to around 70,000 radicals forming a Communist Party in the U.S. This was a response to growing social and economic problems, including the Great Depression and racial discrimination. Additionally, fears of communism were heightened by the Red Scare and bomb threats targeting government and business leaders in the U.S.
