The answer is D The Declaration of Independence
"Mass society is any society of the modern era that possesses a mass culture and large-scale, impersonal, social institutions. A mass society is a society in which prosperity and bureaucracy have weakened traditional social ties" This is the definition of mass society theory. I would thus hypothesize that mass society strengthens the economy greatly but likely abolishes leisure activities for the sake of economic success.
I hope this helps!
