One way the government can restore competitiveness in a market is through:

a) patents.

b) copyrights.

c) tariffs.

d) taxes.

e) antitrust laws.

The correct answer is e) antitrust laws.

• This is because antitrust laws prevent a company in the industry from taking actions that would result in less competition in the market (e.g. the top producer acquiring the second-biggest producer). Patents and copyrights do not affect the market's competition but rather the legal environment, whereas tariffs and taxes are related to government revenue.
