Which is a characteristic of popular culture?
a) quick to change its commonalities..
b) defined by region or location.
c) practiced by a homogeneous group of people.
d) defined by existing within the dominant culture.

My guess is D because popular means a lot of people like it, and dominant culture is the most powerful

The answer is "A" because on of the characteristics of popular culture is heterogeneous people who stretch across the world so its not C and its not B for obvious reasons and D just sounds dumb.

Water flows along the east coast and across the western tropical pacific towards south america, while they both are directed towards that way,  el niño does not directly affect the southern flow of water along the coast.
