The Populist Party, which emerged in the late 19th century, primarily focused on addressing the economic challenges faced by farmers and the working class. Among the options listed, the Populist Party believed that 1. currency reform would help solve U.S. economic problems. They advocated for the free silver movement, which aimed to increase the money supply and make it easier for farmers to pay off debts.
The other options—savings banks, new policies on Native Americans, and renewed immigration policies—were not central to the Populist Party's agenda for addressing economic issues.
