Answer 1

Between 1870 and 1890, the map would show a great expansion of railroads in the West, highlighted by the connection of four transcontinental lines that brought together the West Coast with regions across the Mountain West and the Great Plains.

Step-by-step explanation:

The change the map shows between 1870 and 1890 is C. Railroads expanded greatly in the West. This expansion was a significant part of the second industrialization wave that took place in the late nineteenth century, which led to increased urban growth across the East and Midwest due to the development of transportation infrastructure such as railroads and telegraph lines. By 1887, there were four transcontinental lines connecting the West Coast with the expanding railroad network throughout the Mountain West and Great Plains, transforming the American economy and linking various communities across the nation.
