Final answer:
The goal of the legislation was to ensure fair business practices.
Step-by-step explanation:
The goal of legislation like the Interstate Commerce Act, Sherman Antitrust Act, and Clayton Antitrust Act was to ensure fair business practices. These acts were passed to regulate and prevent monopolistic behavior in the marketplace. The Interstate Commerce Act created the Interstate Commerce Commission to supervise and regulate the railroad industry, while the Sherman Antitrust Act made it illegal to monopolize or conspire to restrain commerce. The Clayton Antitrust Act further clarified and expanded on the definitions of illegal business practices and aimed to prevent the growth of monopolies.
