Explanation:

The Market Revolution in the 19th - century United States was driven by several factors, including technological advancements. The steam engine was a crucial technology. It was used in steamboats (improving river transportation) and later in railroads (revolutionizing land transportation). This made the movement of goods across long distances more efficient, expanding markets.
Telephones became prominent later (in the late 19th and 20th centuries, well after the main phase of the Market Revolution). Automobiles were also a 20th - century innovation. Coal - powered engines were more of a general description, and the specific and widely impactful technology for transportation and industrial growth during the Market Revolution was the steam engine.
