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 determine the correct statement, we analyze each option:

• Option 1: During the late 1800s, railroad expansion in the West required timber for construction (tracks, bridges, etc.), so Western forests were cut down. This aligns with historical context.
• Option 2: Railroad expansion disrupted bison habitats, and bison were hunted near tracks, not "allowed to roam" freely. Eliminate.
• Option 3: Bison were hunted to near - extinction, not domesticated, to clear land for railroads. Eliminate.
• Option 4: Railroad expansion focused more on the West (transcontinental railroads), and Eastern forests were not the primary source for railroad - related deforestation. Eliminate.

Answer:

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