Question

when a company has a monopoly, what does this indicate?
international trade dominance
partnership with labor unions
shared ownership with government
complete market control of a product or service

Explanation:

A monopoly means a single - seller situation in the market. It is about market control, not international trade dominance (which is more about a country's position in global trade), partnership with labor unions (a labor - management relation), or shared ownership with government (a form of public - private partnership). The key concept of monopoly is having complete control over the supply of a particular product or service in the market.

Answer:

Complete market control of a product or service
