Explanation:

The excerpt describes Standard Oil monopolizing the industry. Monopolies led to calls for anti - trust laws. The Sherman Anti - Trust Act was passed to address such monopolistic practices. Imperialist policies (related to overseas expansion), the Social Security system (a welfare program), and dependence on foreign fossil fuels (a later - 20th - century issue) are not related to the described monopolistic actions.

Answer:

The Sherman Anti - Trust Act was passed.
