how did steam locomotives lower the cost of transporting raw materials and finished goods?\n○ they cost nothing to run because they ran on steam.\n○ they could transport many materials or goods at once.\n○ they were uncomplicated and inexpensive to build.\n○ they were safe and cut the chance of costly accidents.
Answer
Brief Explanations:
To determine the correct answer, we analyze each option:
- The first option is incorrect because steam locomotives do have operating costs (e.g., fuel, maintenance).
- The second option is correct. Steam locomotives had a large carrying capacity, allowing them to transport many materials or goods at once. This economies of scale reduced the per - unit cost of transportation.
- The third option is incorrect. Steam locomotives were complex and expensive to build, requiring advanced engineering and materials.
- The fourth option is incorrect. While safety was a concern, the main way they lowered transportation costs was through their large - scale carrying capacity, not primarily through reducing accident rates.
Answer:
B. They could transport many materials or goods at once.
