Problem: Miami:

Black labor played a crucial role in Miami's early development. During the beginning of the 20th century, migrants from the Bahamas and African-Americans constituted 40 percent of the city's population. Whatever their role in the city's growth, their community's growth was limited to a small space. When landlords began to rent homes to African-Americans in neighborhoods close to Avenue J (what would later become NW Fifth Avenue), a gang of white man with torches visited the renting families and warned them to move or be bombed.

Where did a portion of Miami's black population migrate from in the early 1800s?

Problem: Canadian football:

Canadian football has mostly been confined to Canada, with the United States being the only other country to have hosted a high-level Canadian football game. The CFL's controversial "South Division" as it would come to be officially known attempted to put CFL teams in the United States playing under Canadian rules between 1992 and 1995. The move was aborted after three years; the Baltimore Stallions were the most successful of the numerous Americans teams to play in the CFL, winning the 83rd Grey Cup. Continuing financial losses, a lack of proper Canadian football venues, a pervasive belief that the American teams were simply pawns to provide the struggling Canadian teams with expansion fee revenue, and the return of the NFL to Baltimore prompted the end of Canadian football on the American side of the border.

When was the Grey Cup aborted?

A: unanswerable


Problem: Protestantism:

Protestants have founded hospitals, homes for disabled or elderly people, educational institutions, organizations that give aid to developing countries, and other social welfare agencies. In the nineteenth century, throughout the Anglo-American world, numerous dedicated members of all Protestant denominations were active in social reform movements such as the abolition of slavery, prison reforms, and woman suffrage. As an answer to the "social question" of the nineteenth century, Germany under Chancellor Otto von Bismarck introduced insurance programs that led the way to the welfare state (health insurance, accident insurance, disability insurance, old-age pensions). To Bismarck this was "practical Christianity". These programs, too, were copied by many other nations, particularly in the Western world.

What did Bismarck consider social insurance programs to be?
