Final answer:
The National Civil Liberties Bureau was not used to ensure American public support for the war effort during World War I, unlike propaganda campaigns, loyalty leagues, and the Sedition Act.
Step-by-step explanation:
The National Civil Liberties Bureau was NOT used to ensure American public support for the war effort during World War I. The National Civil Liberties Bureau actually worked to protect civil liberties and defend individuals who opposed the war. On the other hand, propaganda campaigns, loyalty leagues, and the Sedition Act were all used to ensure American public support for the war effort. Propaganda campaigns aimed to shape public opinion and generate support for the war. Loyalty leagues were organizations that promoted patriotism and loyalty to the government. Lastly, the Sedition Act was passed in 1918 to suppress opposition to the war, making it a crime to criticize the government or the war effort.
