A cultural transition zone is best described as:

• A. Region with a single dominant culture
• B. Area where two cultures meet and exchange traits
• C. Region with no cultural interaction
• D. Zone defined by climate transition only

Answer: (B)

The main idea is how cultures interact across a boundary. A cultural transition zone is the area where two cultures meet and exchange traits—language, clothing, food, technologies, religious practices—so cultural influences blend rather than stop abruptly. Because people, ideas, and goods move across this boundary, traits diffuse and vary gradually from one side to the other, creating a mosaic of influences. This makes it the best description for a zone shaped by ongoing cultural exchange. If you imagined a region with a single dominant culture, that wouldn’t capture the boundary dynamics. If there were no cultural interaction, diffusion wouldn’t occur. If the definition rested solely on climate, it would describe a climatic or ecological transition, not a cultural one.
