I'm writing a DBQ for class and i just need help getting started. The question is To what extent did the Supreme Court advance or inhibit Progressive regulation of corporations in the period 1885-1920?

So Far i have come up with this for my thesis: In the Late 1800’s and early 1900’s, the United States Supreme Court did not advance progressive regulation despite introducing the Sherman Antitrust Act to regulate against monopolies and the Interstate Commerce Act that attempted to regulate railroad companies. The Sherman Act declared illegal all combinations “in restraint of free trade.” It empowered the Justice Department to bring suit and break up such monopolies. However, these documents would have the pass the scrutiny of the Supreme Court and would have to be enforced.

If you have anything i can add or change it would be greatly appreciated.
