A line graph showing supply and demand. The x-axis is labeled Quantity. The y-axis is labeled Price and has points marked, from bottom to top, P2, P3, and P1. There are four lines on the graph. They are labeled S1, S2, S3, and D. Line S1 is a dashed line and shows a stead increase in price as quantity increases. It intersects the S2 line at a price of P2, it intersects the S3 line at a price of P3, and it intersects the D line at a price of P1. Line S2 is a solid line that is constant at a price of P2 for all quantities. Line S3 is a solid line that is constant at a price of P3 for all quantities. Line D is a solid line that runs perpendicular to the S1 line. It shows a steady decrease in price as quantity increases. It intersects S1, S2, and S3."%0D%0A%0D%0AWhat does S3 most likely represent?%0D%0A%0D%0AMultiple Choice%0D%0A%0D%0Aproduction possibilities under conditions of free trade%0D%0A%0D%0A%0D%0AU.S. supply under quota-restricted trade%0D%0A%0D%0A%0D%0AU.S. supply under tariff-restricted trade%0D%0A%0D%0A%0D%0Athe result of a foreign country dumping this good on the U.S. market
