The correct answer is: The war effort required American civilians to contribute
Total war is a term of the twentieth century that describes a war in which countries or nations mobilize and force to the limit all available resources, whether human, military, industrial, agricultural, natural, technological, scientific, or of any other kind, to totally destroy the ability of another country or nation to engage in a war. The practice of total warfare has been used for centuries, but it was not until the mid-nineteenth century that it was recognized as a different way of waging war.
In other cases, the total war involved the maximum effort within the conflicting powers, such as the effort that civilians should make in the consumption of food or water during the conflict.
