the supreme court ordered the breakup of the standard oil company.
president theodore roosevelt gave her a medal for her journalistic efforts.

Explanation:

Ida Tarbell was a muckraker who wrote about the Standard Oil Company. Her work exposed the company's monopolistic practices. The Supreme Court's action against Standard Oil was a result of such exposés. The Pure Food and Drug Act was more related to Upton Sinclair's The Jungle. Tarbell was not imprisoned, and there's no record of Roosevelt giving her a medal for this.

Answer:

The Supreme Court ordered the breakup of the Standard Oil Company.
