In the Commanding Heights video, you saw that during the 1920 's the U.S. economy was probably at q, on the graph from page 275 . By 1931 we were near point q, The Classical/Austrian economists of that time period argued that the government should: a. Point A or even higher in segment III of the aggregate supply curve; B; not intervene in the economy because in the long run wages and input costs would fall causing aggregate supply to increase and the restoration of full employment. b. E; D; increase taxes in order to reduce aggregate demand and lower the rate of inflation. c. A; D; increase government spending on infrastructure programs in order to push aggregate demand closer to point E. d. C ; B ; lower interest rates and increase government spending in order to create a multiplier effect that would stimulate aggregate demand in the short run and aggregate supply in the long run.

3. Consider the 5 x 6 matrix \begin{pmatrix} 2 & 1 & 1 & 3 & 0 & 4 \\ 4 & 2 & 4 & 4 & 1 & 5 \\ 2 & 1 & 3 & 1 & 0 & 4 \\ 6 & 3 & 4 & 8 & 1 & 9 \\ 0 & 0 & 3 & -3 & 0 & 0 \end{pmatrix} $P =$ with columns labelled $C_1, C_2, \dots, C_6$. Answer the questions and justify your answers. (a) What is the rank of P? (b) Which are the basic columns of P? (c) Express the non-basic columns of P as linear combinations of the basic columns. (d) Suppose that $P = (A \mid B)$ is the augmented matrix for a 5 × 5 system of linear equations $AX = B$. What are all solutions? (e) If P is as in (3d), what are all solutions to the homogeneous system $AX = 0$?
