In recent decades, many world historians have challenged the view that the First World War did not differ substantively from previous major wars in world history. All of following support this historical reinterpretation EXCEPT a. despite the carnage caused by the First World War, fighting was confined to western Eurasia and, despite the use of new weaponry, casualties were relatively low as the war lasted only one year.
b. the geographic extent of the First World War surpassed any previous war, with people on five continents compelled to be directly or indirectly involved in a war many did not understand.
c. nations committed to total war, mobilizing resources and using propaganda on an unprecedented scale. d the First World War was industrial in scope and military technologies caused unprecedented loss of life of combatants and civilians, maimed millions, and caused emotional harm in much of the world population.
