01 In which situation would the network approach in human geography be most useful?
Answer and explanation
Correct answer: B. Understanding transport, information, and trade flows among cities
Explanation: The governing concept of the network approach is the study of connections among places, nodes, routes, and flows. In a human-geographical network, cities may function as nodes, while roads, railways, shipping lanes, pipelines, digital links, and trade routes connect them. Analysing these links helps explain how people, goods, money, services, and information move through space and why some places become more connected than others. Thus option B is correct. Measuring a mountain, identifying soil in one field, or measuring river depth focuses mainly on a physical feature at a single location. Those tasks may be geographical, but they do not primarily investigate an interconnected human system.
