Final answer:
American culture has transformed from an agrarian base to the information age, which is characterized by advances in technology that have reshaped many aspects of life, from work and communication to global cultural interactions.
Step-by-step explanation:
The changes in American culture from the early days of farming to the present can be perceived in different ways. Based on the information provided, though, it seems most accurate to describe the evolution as moving toward the information age, which is option b. This era is marked by significant technological advances, such as industrialization, the advent of computers, the Internet, and cell phones, which have fundamentally altered the ways people communicate, work, learn, and trade. These technologies catalyzed a shift from an agrarian society to an industrial one, and now to an information society, influencing not just American culture but sparking changes in global culture as well.
This shift to an information society has increased global communication, thereby facilitating the emergence of a more unified global culture, despite traditional barriers such as distance, language, and different social customs. Advances in transportation and communication have made it possible for ideas and cultural products to be exchanged more freely and rapidly, impacting social relationships, business practices, and even the perception of morality and success.
