Answer:
An example of total war during World War I would be that all food and supplies were sent to soldiers, while civilians starved at home.
Explanation:
Total war is a type of war in which not only the armies but the whole of society fights, not on the battlefront but on the domestic front, through the redirection of the productive effort from the civilian to the military. Thus, the nation allocates all its resources and efforts to its military objectives, in order to win the conflict.
Thus, for example, the fact that most of the food resources and supplies were destined to cover the needs in the battle front, momentarily putting aside the needs of civil society, is a clear example of total war, in the that not only the soldiers, but the nation as a whole, make efforts to win the war.
