The major points of the Treaty were: 1. Germany would take all blame for starting the war. 2. Germany would pay reparations to the other nations for all the damage that occurred during the war. 3. Germany was not allowed to have an airforce nor submarines. They were also to cut the army to 100k men. There was also certain stretched of land where they could not operate nor station men. 4. Germany also lost territories, mainly their colonies.
The Allies set these terms because: 1. They needed justification for the punishments that they were going to set on Germany. 2. By cutting Germany's military and forcing them to pay, Germany wouldn't have the funds nor the manpower to attempt anything like what had just occurred. 3. By taking territory, Germany would lose it's sphere of influence and other vital trade markets. The goal was to cripple Germany. The treaty was successful in that. It also led to extreme bitterness in the German people. This, along with a worldwide depression, allowed for the rise of Hitler and the Nazi regime.
Internal validity would be the extent through which a record an accounting a reliable reason as well as effect correlation among both medications as well as consequence.
Perhaps it speaks to the fact that the original study ends up making it achievable to help reduce possible causes for something like a discovering.
