Praxis 5004 Practice Test Practice Question

Which of the following contributed most to rapid expansion west of the Mississippi in the second half of the nineteenth century?

Correct Answer: C

Rationale: The construction of railroads played a pivotal role in the rapid westward expansion by providing efficient, reliable transportation for goods and people across long distances. Railroads significantly reduced travel time and costs, facilitating migration and commerce.

In contrast, the proliferation of steamboats (A) primarily benefited river transportation and did not cover the vast overland distances. Development of canals (B) improved trade routes but was limited to specific areas and lacked the flexibility of railroads. Similarly, construction of turnpikes (D) enhanced road travel but could not match the speed and capacity of rail systems, making railroads the most impactful factor in westward expansion.
