4. What did the U. S. in preparation for war before participating in the war?

With the financing, transportation, equipment, food, and men in place, the United States was ready to enter the war. The next piece the country needed was public support.

:-))

congress failed to remove johnson. but it did succeed in getting control of efforts to re-build the south following america's civil war. radical republicans wanted to punish the south for starting the war. they also wanted to be sure new governments in the southern states would support the republican party.

the answer is b. hope this !
