The Niagara Movement was a civil-rights group founded in 1905 near Niagara Falls. Scholar and activist W. E. B. Du Bois gathered with supporters on the Canadian side of Niagara Falls to form an organization dedicated to social and political change for African Americans. Its list of demands included an end to segregation and discrimination in unions, the courts, and public accommodations, as well as equality of economic and educational opportunity. Although the Niagara Movement had little impact on legislative action, its ideals led to the formation of the National Association for the Advancement of Colored People (NAACP) in 1909.
The correct term is voter turnout.
Voter turnout represents a percentage of how many eligible voters came out and participated in a recent election. Demographics refers to breaking down individuals who voted in elections based on different factors like race. The other two terms are somewhat unrelated to voting.
The best option from the list would be the "British," but it should be noted that the French and Spanish were also early colonizers of the land that would become the US.
Both The US, UK, and USSR knew that annexing the the Nazi heartland in Berlin would end the war within the European theatre through and allied victory. Early in 1945, Stalin, Churchill, and Roosevelt agreed to meet to discuss the postwar political environment of Europe. Even though they agreed to separate Berlin into separate zones, both the US and USSR feared one another's influence would be stronger over postwar Europe (as the UK would not be as dominant a power due to exhaustion from the war). Therefore, it was a race for both sides to reach Berlin first, as it was believed the first to get there would have a stronger influence over the events following Germany's loss in WWII
