Question

which of the following statements best describes how railroad expansion affected the environment during the late 1800s?
western forests were cut down to build railroads and bridges.
wild bison were allowed to roam near railroad tracks.
wild bison were domesticated to make room for railroads.
eastern forests were cut down to build railroads and bridges.

Explanation:

To solve this, we analyze each option:

• Option 1: During late 1800s railroad expansion in the West, forests were cut for railroad/bridge construction. This matches historical context.
• Option 2: Railroad expansion led to bison hunting (not roaming freely near tracks), so incorrect.
• Option 3: Bison were hunted, not domesticated, to make room for railroads, so incorrect.
• Option 4: Railroad expansion was more in the West, not Eastern forests for this purpose, so incorrect.

Answer:

A. Western forests were cut down to build railroads and bridges.
