Question

how did carnegie’s early job with the railroads greatly contribute to his success in the steel business?

• it taught him how to lay railroad tracks with steel.
• the pennsylvania railroad company was his best customer when he built his business.
• the pennsylvania railroad company paid him well enough so he eventually could invest in his own business.
• it helped him predict that the demand for steel to build railroad tracks and bridges would grow.

Explanation:

To solve this, we analyze each option:

• Option 1: Carnegie's success in steel wasn't about laying tracks. Eliminate.
• Option 2: The railroad being his best customer isn't the main contribution from his early job. Eliminate.
• Option 3: Being paid well to invest isn't the key contribution; his insight into demand is more critical. Eliminate.
• Option 4: His early railroad job gave him insight into the growing demand for steel in railroad infrastructure, which was crucial for his steel business success. This makes sense.

Answer:

It helped him predict that the demand for steel to build railroad tracks and bridges would grow.
