Answer 1

Vertical integration was the business practice that contributed most to Andrew Carnegie's ability to form a monopoly.

Step-by-step explanation:

Andrew Carnegie's ability to form a monopoly was most contributed by vertical integration. Vertical integration is a business practice in which a company controls all aspects of production, from raw materials to the finished product. By acquiring and owning the suppliers, such as mines, freighters, and railroads, Carnegie was able to cut costs and ensure a quality product. This practice allowed him to dominate the steel market and eventually sell his steel factory to J.P. Morgan, creating the United States Steel Corporation.
