The main idea being tested is how a market is organized in terms of competition. Market structure describes the broad arrangement of a market with respect to competition, including how many firms operate, how similar the products are, and what barriers to entry exist. These features determine how competitive the market is and how firms behave—think of setups ranging from many firms selling identical products to a single firm dominating with unique offerings.

Market equilibrium refers to the point where supply equals demand, giving a price and quantity that balance the market, not how the market is organized. Equilibrium quantity is simply the quantity traded at that equilibrium price. Price controls are government actions that set or limit prices, which affect outcomes but do not describe the competitive architecture of the market. So market structure is the term that best captures the idea of the market’s competitive arrangement.
