Why are geographers interested in the information in DOLLY?

Geographers are particularly interested in DOLLY because it provides information about the spatial distribution of people's reactions to events. Understanding how different populations respond to various occurrences—such as natural disasters, political changes, or social movements—can offer valuable insights into human behavior and societal dynamics. This information allows geographers to analyze trends in reactions based on geographic location, social factors, and local cultures, enhancing their ability to interpret the interconnectedness of space and human activities.

The other choices, while relevant to geography in broader contexts, do not specifically align with the focus of DOLLY. The data on transportation routes helps in logistics and urban planning but does not directly concern human reactions. Similarly, while patterns of cultural exchange are integral to the study of geography, they do not capture the immediate human responses to events as DOLLY does. Finally, tracking climate change effects is crucial in geography, but it pertains more to environmental studies than to the social reactions emphasized by the information DOLLY provides.
