Cultural traits spread throughout the world in many different ways. In the modern world, innovations in communication technologies have resulted in an increase in the sharing of cultural traits. This sharing of traits concerns some sociologists, however, because they believe it could lead to
A.
a decrease in trade barriers.
B.
a decrease in cultural diversity.
C.
an increase in the number of world religions.
D.
an increase in warfare between cultures.
It would have no effect on trade barriers, it would increase cultural diversity, not decrease it, and an increase of world religions wouldn't necessarily be a bad thing. Therefore the only answer that makes sense would be D.
