Final answer:
The proposed legislation to cap domestic prescription drug pricing at foreign prices represents a price ceiling, which is a legal maximum price set to keep consumer costs low.
Step-by-step explanation:
The price controls described in the news clip are an example of a price ceiling. A price ceiling is a legal maximum on the price at which a good can be sold, in this case, prescription drugs. It is intended to keep prices low for consumers. This contrasts with a price floor, which is a legal minimum on the price at which a good can be sold. The intention behind the proposed legislation to cap domestic pricing at foreign prices is to prevent prices from rising above a certain level, with the aim of making prescription drugs more affordable for consumers.
