Answer:
Forbid combinations in restraint of trade and monopolizing.
Explanation:
The Sherman Antitrust Act of 1890 is mainly aimed at preventing anti competitive agreements and unilateral conduct by a group of businesses aligning with one another. Such alignment results in restraint of trade and monopoly.
This Act enables the Department of Justice to bring charges against violators of antitrust laws and they may face as much as treble damages (three times of the damage caused to other parties).
Artificial raising of price and restriction of supply of products or trade are prohibited under this Act.
