Which field uses cross-regional comparisons to understand revolutions or reforms?

• A. Comparative history.
• B. Ethnography.
• C. Numerical accounting.
• D. Meteorology.

Answer: (A)

Cross-regional analysis of historical changes to uncover patterns and driving forces behind revolutions and reforms. This approach is best captured by comparative history, which deliberately looks at cases from different places and times to identify common factors, differences, and how context shapes outcomes. By examining multiple regions, you can see which pressures—economic stress, political structures, ideologies, or external influences—tend to trigger change and how those changes unfold in various settings.

Ethnography, for example, studies cultures through deep, on-the-ground fieldwork within a particular community, rather than across multiple regions to compare large historical processes. Numerical accounting focuses on tracking and analyzing financial data, not on explaining broad political and social transformations. Meteorology deals with weather and atmospheric phenomena, not revolutions or reforms.
