Pittsburgh's evolution included an early function connected to defense, followed by a steel manufacturing phase, and later a shift to diverse services. What is the late phase described?

• A. Diverse services (financial, light manufacturing)
• B. Defense
• C. Steel manufacturing
• D. Tourism

Answer: (A)

Economic shifts over time show a city moving from heavy production to a diversified services base. In Pittsburgh, defense-related activity started things, then steel manufacturing dominated for decades, and eventually the economy pivoted to a broad mix of services. The late phase described—diverse services including financial activities and light manufacturing—captures that sustained shift toward knowledge-based, service-oriented activity alongside lighter production. Tourism is part of the services spectrum, but the description best fits a broad diversification into finance and other service sectors rather than sticking with defense, steel, or only tourism.
