3. How did the great migration contribute to the social unrest in the U.S.? 
Schafer takes a macro approach to the phenomenon, looking at large economic forces which propelled large numbers of people to act. Schmidt, on the other hand, looks at individual players and actors. In his view, the decisions of millions of individuals must be taken into account in order to tell the larger story. History is not the work of impersonal economic forces, but rather is the action of men and women who make decisions. The Great Migration was the result of many small migrations.

4. How did the "Red 
Summer" in Chicago contribute to the social unrest in the  U.S?
On July 27, 1919, an African-American teenager drowned in Lake Michigan after violating the unofficial segregation of Chicago’s beaches and being stoned by a group of white youths. His death, and the police’s refusal to arrest the white man whom eyewitnesses identified as causing it, sparked a week of rioting between gangs of black and white Chicagoans, concentrated on the South Side neighborhood surrounding the stockyards. When the riots ended on August 3, 15 whites and 23 blacks had been killed and more than 500 people injured; an additional 1,000 black families had lost their homes when they were torched by rioters.
