Which statement about american society in the 1950s is correct?
a. most people in suburbia could not afford cars.
b. most americans of the 1950s lived on farms.
c. many middle-class suburban women were unhappy with their circumstances.
d. most suburban neighborhoods had a lot of racial and ethnic diversity.

If you lived in suburbia chances are you could probably afford a car. By the 1950s farms weren't as much as a majority as they were back in the 1800s, so B is ruled out as well as A. Racism was still a pretty big thing in the '50s, and I believe that was when the "separate but equal" stuff was going on. So my best guess would be C) Many middle-class suburban women were unhappy with their circumstances. 

It's C. Many Middle-class suburban women were unhappy with their circumstances.
