What can popular culture tell us about a historical time period? Are
trends in music, film, and television important for understanding an
era? Why or why not?

The correct answer to this open question is the following.

What can popular culture tell us about a historical period is the way people lived and thought during that particular period in history. Often, artists -in this case, musicians- write music about the things that are happening daily in society. Music describes moods, feelings, and relate stories of each epoch. Trends in music, film, and television are important for understanding an era because as ion the case of music, they reflect the things, customs, traditions, tendencies, and the life of people in any period. Artistic expression is the result of the life of people in different moments. For instance, the counter-culture of the 1960s and 1970s, that represented a culture change in youth and American society.
