Are there any answer choices? If not, I believe one is oil.
Central powers: (WW1)
Germany, Austria-Hungary, and Turkey
Axis Powers: (WW2)
Germany, Italy, and Japan
My teach told me as well put the central powers just in case.
Sorry if I am wrong.
For Germany the treat of Versailles dealt them a heavy hand. They were imposed land, economic and military restraints as well as forced to pay a great deal of the reparations cost for countries like France. Whom during world war one had received heavy damages.
More specific on territory, Germany's land were split between different nations. Such as the Rhineland which they were prohibited from occupying after losing the war.
Hope it somewhat helps :)
