Explanations:
One of the main provisions of the Treaty of Versailles was the creation of thee League of Nations. The League of Nations was an organization that believed in world peace, and wanted all of the nations around the world to communicate and be in peace with one another. The League of Nations was one of the reasons why Germany surrendered, since the League of Nations overpowered them.
Another main provisions of the Treaty of Versailles was Germany losing parts of its territory. Germany lost world war I, and because of that, they had to surrender part of its territory to the winning countries, specifically the countries in Europe. It gave the land that Germany took back to its orignal countries.
Another main provisions of the Treaty of Versailles was Germany's military restrictions. Because of the Treaty, the countries made restrictions to Germany's military, which made their military weaker, so they don't end up fighting another war (which they did in WWII). Germany was restricted to 100,000 people in their army, which is a little compared to other countries military population.
The last main provisions of the Treaty of Versailles was the guilt of Germany from the war. Because Germany lost the war, the Allies made Germany pay $33 billion dollars to repair the damages that were caused during WWI. They made Germany pay for it because they were the one's that were fighting them, and since they lost, they lost their superiority.
