Question

How was Rockefeller’s monopoly different from Carnegie’s?

Answer 1

The correct answer is:  

C. Rockefeller combined many corporations into a trust.

Rockefeller´s Standard Oil company bought up his competitors, and created the US’s first monopoly. Combining many corporations into a trust meant that holders of stock from oil companies handed over their shares to Rockefeller and his associates as a board of trustees, getting in return ‘trust’ certificates which paid dividends without any power.
