Question

which example shows cultural diffusion along the silk road?
merchants refusing to trade technologies
local rulers banning foreign languages
buddhism and islam spreading to new regions
cities isolating customs from travelers

Explanation:

Cultural diffusion is the spread of cultural elements (like religion, ideas, customs) between societies. The Silk Road facilitated the spread of religions like Buddhism and Islam to new regions. The other options (merchants refusing trade, rulers banning foreign languages, cities isolating customs) represent resistance to cultural exchange, not diffusion.

Answer:

C. Buddhism and Islam spreading to new regions
