Explanation:

Ida Tarbell's History of the Standard Oil Company exposed the company's monopolistic practices. This led to legal action. In 1911, the U.S. Supreme Court ordered Standard Oil to dissolve under the Sherman Antitrust Act. The company was split into 34 smaller companies, ending its monopoly. There is no evidence that the profit - sharing with employees, back - tax payment, or workplace safety changes were direct results of Tarbell's work.

Answer:

The company was forced to split up, ending the monopoly.
