Answer:
C. People were more inclined to believe in radical views.
Step-by-step explanation:
The Great Depression caused devastation throughout all America and the post World War I Europe. Especially in Germany.
People then began to feel despise to the politicians of that time because they were guilty of letting the Depression happened. With that context, people with good oral skills could convince people to tend to radical views in order to get over that period.
One major example of it was the arising of Hitler in Germany. Who, with great oratory skills came to power in Germany after the Great Depression convincing people that his radical points of view would be the politics that helped them to pass the crisis.
