01 Which is an example of a functional relationship in human geography?
Answer and explanation
Correct answer: B. A city and its surrounding daily commuting zone
Explanation: A functional relationship is based on interaction, flows, and complementary roles between places rather than on simple physical similarity. Option B is correct because a city and its surrounding commuting zone are linked by regular movement of workers, transport services, employment, education, shopping, and other urban functions. Equal rainfall, elevation, or soil may help identify areas with similar physical characteristics, but they do not prove that the places interact. The commuting connection demonstrates a functional region created by repeated social and economic exchanges.
