Which study focuses on explaining how innovations in transportation and communication transformed the economy?

• A. Explaining how innovations in transportation and communication transformed the economy
• B. Explaining how corporate leaders tried to limit competition
• C. Comparing the careers of prominent industrial leaders
• D. Comparing ways in which businesses organized the work process

Answer: (A)

The main idea being tested is how innovations in transportation and communication drive economic change. The best choice describes a study that explains the impact of those innovations on the economy itself—how faster transport and instant communication expand markets, lower costs, enable larger-scale production and distribution, and shift patterns of trade, labor, and development. This is the type of analysis economists use to understand economic transformation over time. The other options focus on different topics: corporate leaders trying to limit competition, the careers of industrial leaders, or how businesses organized work processes. While those topics are valuable in their own right, they don’t address how innovations in transportation and communication reshape the economy as a whole.
