Accepted Answer

# Brief Explanations:
The excerpt describes the completion of transcontinental railroads in the 1860s. Analyzing each option:
- Option A: The excerpt does not mention political mobilization by merchants for transportation expansion.
- Option B: Railroads enabled the growth of new towns and commercial hubs along their routes, a direct and well-documented effect of 19th-century railroad expansion in the U.S., which aligns with the context of transcontinental rail completion.
- Option C: There is no reference in the excerpt to increased government control over transportation industries.
- Option D: The excerpt does not state that new immigrants mostly settled on western farms via rail; railroads facilitated settlement but this option's specific claim is not supported by the given text.
# Answer:
B. New commercial centers and communities emerged along rail lines
