Answer:
An act that extended the Espionage Act of 1917
Step-by-step explanation:
The Sedition Act of 1918 was an Act of the United States Congress that extended the Espionage Act of 1917 to cover a broader range of offenses, notably speech and the expression of opinion that cast the government or the war effort in a negative light or interfered with the sale of government bonds.
It was an attempt at silencing people who disagreed with the government.
