Although there are no options attached we can say the following.
The actions of significant individuals were the main factor in the rise of Nazism in Germany in the 20th Century to the extent that prominent figures of that time like Adolph Hitler not only caught the attention of German people, but he can convince them that he was the "chosen one" to change the face of the nation and put Germany in the highest place it deserved.
The Great Depression affected Germany in that the Weimar Republic lived heavy inflation in the decade of 1920 because Germany had to pay many reparations due to World War 1 and the agreements of the Versailles Pact.
