The correct answer to this open question is the following.
Although there are no options attached we can say the following.
The quote is "if the Treaty of Versailles war fair, the Second World War would not have occurred."
I can justify this statement? in the following way.
The victorious allies in World War I forced Germany to pay for war reparations. Yes, France and Great Britain did not really want a peace treaty. They wanted retribution and forced Germany to pay for all the destruction created during the war.
Germany was especially opposed to Article 231 of the Treaty of Versailles because it held Germany (and Austria) responsible for the war and required reparations. Germany also was forced to disarm its military.
In the end, this also resulted in a substantial loss of territory for Germany. All of these decisions and actions created so much pain and resentment in Germany. They helped set the stage for European conflict that would eventually result in World War II.
