PLEASE HELP I NEED THIS NOW!! What was a sign that nations were determined to fight World War I, a "total war," to the bitter end?

Women joined the military and faced combat conditions for the first time.

Nations used only trained professional soldiers instead of volunteers.

Instead of being thirteen republics, under a federal head, [the federalists’ plan] is clearly designed to make us one [unified] government. . whether such a change can ever be [made] in any manner; whether it can be [made] without convulsions and civil wars; whether such a change will not totally destroy the liberties of this country—time only can determine. –the federal farmer what best summarizes the point of view the excerpt expresses? in time, one unified government will run the country. the federalists prefer thirteen republics to one unified government. one unified government probably will not lead to disruptions and civil wars. under one unified government, people will be robbed of their freedoms.
