<em>They helped farmers transport their goods to wider markets.</em>
Explanation:
Railroads helped farmers in the late 1800s by using them to transport their goods to wider markets.
During this time, it was still very rural, particularly in the South. While the North was beginning to become industrialized, the South was still bare and rural, except for farms.

Railroads greatly helped farmers by not only covering these distances quickly but by taking the goods even farther and taking them to wider markets.
