The correct answer to this open question is the following.
What is not an example of racism experienced by African Americans at the turn of the twentieth century is the forced relocation of black people to cities in the north part of the United States.
What US historians considered to be the Great Migration of African Americans to large cities of the North started in 1916 and ended by 1970. Black people that lived in the poor and rural regions of the South decided to move up North, trying to find better economic and living conditions for their families. Scholars affirm that almost 6 to 7 million African Americans moved during that period.
