Question

the building of a railroad network led to industrial growth because
raw materials and finished products were shipped quickly and cheaply.
finished products were shipped quickly to rural canada.
finished products were shipped quickly and cheaply to factories.
raw materials were shipped quickly and cheaply to consumers.

Explanation:

Railroad networks enabled efficient, low-cost transport of raw materials to factories for production, and finished goods to markets. This reduced production and distribution costs, allowing industries to scale and drive growth. The other options are narrow or incorrect: the second is limited to rural Canada, the third misdirects finished goods to factories, and the fourth sends raw materials to consumers instead of factories.

Answer:

raw materials and finished products were shipped quickly and cheaply.
