$\begin{array}{l}\text { Domestic Market For Steel, Beta }\\\begin{array}{|c|c|c|}\hline Q_{S} & P & Q_{d} \\\hline 80 & \$ 5 & 20 \\\hline 70 & 4 & 30 \\\hline 60 & 3 & 40 \\\hline 50 & 2 & 50 \\\hline 40 & 1 & 60 \\\hline\end{array}\end{array}$

The accompanying tables show data for the hypothetical nations of Alpha and Beta. $Q_{S}$ is domestic quantity supplied, and $Q_{d}$ is domestic quantity demanded. Assuming that Alpha and Beta are the only two nations in the world, the equilibrium world price must be lower than $\$ 4$ because, at $\$ 4$ ,

A) both nations will export steel.
B) both nations will import steel.
C) Alpha will export steel and Beta will import steel.
D) Beta will export steel and Alpha will import steel.
