Answer: C - Restricted the ability of competitors to engage in cooperative agreements.
Step-by-step explanation:
The Sherman Antitrust Act was signed in 1890 by President Benjamin Harrison. This was named after a senator, John Sherman, who authored the bill himself.
This act prohibits businesses from;
- Anticompetitive agreements
- "Unilateral conduct that monopolizes or attempts to monopolize the relevant market"
- Innocent monopoly
If any business is caught breaking the Sherman Antitrust law the Department of Justice can file suit against the parties involved. The act is made to protect a competitive marketplace for consumers.
