Pittsburgh, PA is described as the center of the steel world due to a close relationship between railroads and which industry?

• A. Steel companies
• B. Oil refineries
• C. Textile mills
• D. Mining companies

Answer: (A)

The main idea is how industries and infrastructure fuel each other. Pittsburgh earned its nickname as the center of the steel world because railroads depended on large amounts of steel for rails, locomotives, cars, and other equipment, and the steel industry in the region grew specifically to meet that demand. The city’s location near abundant coal and iron ore, plus access to rivers for transporting materials, helped steel mills expand and supply the rail networks that were expanding across the country. In this cycle, railroads boost steel production, and steel production, in turn, powers more rail expansion. Oil refineries, textile mills, and mining companies don’t fit as directly with this relationship. Oil refineries focus on petroleum products; textile mills on fabrics; mining companies provide raw ore rather than the finished product railroads needed. The most direct link to making Pittsburgh a steel hub is the steel industry itself.
