Final answer:
An industry described as an oligopoly would most likely have a few large firms that dominate the market.
Step-by-step explanation:
An industry described as an oligopoly would most likely have a few large firms. In an oligopoly, a small number of large firms dominate the market and have most of the sales. Examples of oligopolies include the auto industry, cable television, and commercial air travel. These firms are characterized by mutual interdependence where their decisions on output, pricing, advertising, and other factors depend on the actions of the other firms.
