The correct answer to this open question is the following.
Although there are no options for this question we can say the following.
Mass culture of the 1950s became increasingly homogenous for the following reason.
The decade of the 1950s was homogenous because the government and conservative society tried to establish uniform conduct to alienate the young generations. After World War II, the government used mass media outlets to broadcast information, entertainment programs, and social messages that aimed to maintain control of the status quo in American society.
The result was the conformity of the youngsters and society in general. People decided consciously or unconsciously, to follow the rules established by social norms. Traditional roles and norms for men and women in the family, the workplace, and society were reinforced. Nobody really thought on defy the rules established.
The first signs of rebellion arrived until late that decade with the advent of rock and roll and its many exponents.

The correct answer to this open question is the following.
Although there are no options attached, we can say that the emergent consumer culture changed what it meant to be "American" at the turn of the century in that it represented the rise of many big consumer companies such as "Sears," that turned American people into a consumerism society. The two basic ways in which these new companies tried to sell goods to US citizens were by mail orders or directly in the stores. It was a time in which stores offered many unnecessary things to the American consumer, mostly for leisure time. Those years were the beginning of large retail stores such as Macy's, Marshall Fields, Gimbel's, or Woolworth. It was also a time in which people bought many things on credit. They bought cars, furniture, and home electronics. For instance, that was the case of what was known as the "Roaring 1920s."
