Answer
Please see the graph. The four points are labeled on the two curves.
Work Step by Step
$PC_1$ is the Phillips curve where expected inflation is 3 percent, and $PC_2$ is the Phillips curve where expected inflation is 5 percent.
Since there is expected inflation of 3 percent in these scenarios, the two points on $PC_1$ are A and D. Since there is expected inflation of 5 percent in these scenarios, the two points on $PC_2$ are B and C.
