The correct answer is: "He restored confidence in the government and banks"
The Fireside Chats were 30 evening radio programs conducted by President Franklin D. Roosevelt between 1933 and 1944. He communicated directly with citizens, covering the major issues that affected the US during those years, specially: the recession, the policies implemented by the goverment to deal with it, such as the Emergency Banking Act or the New Deal and, of course, he also delivered needs from WWII, acting as a connection between the battlefield and the civilians that stood back home.
This practice redefined the relationship between the president and the US people, and it ensured the Roosevelt a good consideration as he was a good communicator and citizens felt safe when they listened about serious issues directly from him. He used such influence to restore the confidence of citizens on the banking system after the crash, for example, he explained why he had declared a holiday of several days for the banking sector, what had happened, what people should or should not do in such situation.
