Final answer:
The court ordered the dissolution of Standard Oil into smaller companies in the case of United States vs. Standard Oil.
Step-by-step explanation:
In the case of United States vs. Standard Oil, the court reached the decision to order the dissolution of Standard Oil, breaking it into smaller companies. This landmark decision in 1911 by the U.S. Supreme Court upheld the government's use of the Sherman Antitrust Act to break up Standard Oil, which had controlled about 90% of the country's oil refining. As a result of this decision, Standard Oil was divided into 34 independent firms, which later became known companies such as Exxon, Mobil, Amoco, and Chevron.
