Which is not true of World War I? U-boats were used by the Axis powers. It was a one-front war. Poisonous gases were used by both sides. It was considered a total war.



Answer :

I belive it is that it was a one-front war, becuase there were battles in France and Northern Africa, aming other places, which leads me to say that it was a one-front war.
B.) It was a one front war. Because that is NOT true about world war one. so that would make sense
