Final answer:
WWI defied previous understandings of warfare and helped to define future expectations of it, through its unprecedented scale, military technology, and total war, which altered future war dynamics.
Explanation:
The correct statement that fills in the missing words from the given statement about World War I would be: WWI defies previous understandings of war, and defines future expectations of war. World War I fundamentally altered the nature of warfare with the introduction of new technologies, total war, and the mass involvement of civilians. This contrast reflects how the conflict subverted previous norms and expectations about what war entailed (“defies”), but also how its consequences set a new precedent for how wars would be conceived and conducted in the future (“defines”).
World War I, with its extensive use of military technologies like tanks, machine guns, and airplanes, challenged traditional tactics and strategies of war. Additionally, the vast numbers of troops and civilians involved, along with the high casualties, set a new scale and standard for what was to be expected in future conflicts. This transformative effect of WWI on warfare is captured in the notions of defying past perceptions and defining future dynamics of war.
the answer is defines; defies because it goes along withe sentence
