Explanation:

The Russian Revolution of 1917 led to the establishment of a socialist government. This event heightened fears in the United States about the spread of socialism and anarchism. Immigrants were also viewed with suspicion as potential carriers of these ideologies. The Espionage Act was mainly about preventing interference with the war effort. The arrest of Sacco and Vanzetti was later and related to a specific crime case. The limitation of Chinese immigrants was more about labor - related and racial issues rather than the broad anti - socialist/anarchist sentiment.

Answer:

the outbreak of the Russian Revolution in 1917
