Final answer:
Cultural diffusion is the primary inducer of both major and minor changes within cultures, largely through the exchange of cultural elements between societies.
Step-by-step explanation:
Both major and minor changes within culture are primarily induced by Cultural diffusion (A), which is the movement of an element of culture from one society to another, commonly through migration, trade, or globalization. Cultural diffusion can result in innovation, invention, and hybridity in cultures. Societies also undergo continuous change as they integrate and adapt new technologies or ideas, which are examples of the many catalysts for cultural evolution.
