What did the federal government do to generate support for america's role in world war i ?

established a special agency within the department of defense to respond to questions

sold savings bonds to remind americans to be patriotic about the war effort

provided tax rebates in exchange for military enlistments

formed the committee on public information to create propaganda about the war

The correct response is "formed the Committee on Public Information to create propaganda about the war."

Explanation:

The United States had traditionally been isolationist and avoided getting involved in conflicts abroad, especially those in Europe. WWI started in 1914 but the United States did not join the effort until 1917 when the Zimmermann Telegram (offering to return territories to Mexico if Germany won) was made known to the United States and there were German submarine attacks on US merchant vessels. War on Germany was declared by the US on April 6, 1917. However, there was not a lot of public support for this intervention initially so the government created a committee that was charged with making the climate more favorable for the war effort domestically in the US.
