Question

In the mid to late 1800s, the US government granted land to railroad companies to expand their networks. What is another way that railroad companies used the land?
They mined the land for coal and other natural resources.
They sold the land to farmers and ranchers.
They built factories along the rail lines.
They created land preservations in order to protect the environment.

Answer 1

They sold the land to farmers and ranchers.

Railroads sold much of their granted land to settlers to raise cash for construction and to create customers (freight/passenger traffic); they also sometimes exploited resources on their lands, but they did not create environmental preserves.
