How did the government try to silence opposition to american involvement in world war i? (5 points) by the sale of war bonds by passing the espionage and sedition acts by refusing to use conscription to build the army by allowing women and african americans to serve

The correct answer is
by passing the Espionage and Sedition Acts

These acts silenced opposition because they were conceived in such manner that criticizing your government for its war involvement could be considered treason or espionage for the enemy and so you could go to jail. People didn't want this so they kept their opposition to themselves.
