Question

1. what do antitrust laws seek to prevent?

reduction of competition and monopolies
firms selling products internationally
price discounts for consumers
all mergers and acquisitions

Explanation:

Antitrust laws aim to promote fair competition. Monopolies reduce competition, harming consumers and the economy. These laws prevent such situations. Firms selling internationally isn't their focus. Price discounts (good for consumers) aren't what they stop. Not all mergers/acquisitions are bad; antitrust laws assess them, not prevent all.

Answer:

Reduction of competition and monopolies
