Use the figure to answer two questions.%0D%0A%0D%0AThe horizontal axis is labeled real output in quantity per year and the vertical axis is labeled price level in average price. The concavely upward increasing parallel curves are labeled A S sub 1 and A S sub 2 from left to right. The two decreasing parallel lines are labeled A D sub 1 and A D sub 2 from left to right. A D sub 1 intersects both the curves at the points centering Q sub 1 and Q sub 3, respectively from left to right on the horizontal axis. A D sub 2 intersects both the curves at the points centering Q sub 2 and Q sub 4, respectively from left to right on the horizontal axis. Dashed vertical lines are drawn from the intersection points to the horizontal axis.%0D%0A%0D%0AIn the figure, when AD shifts leftward, what happens to%0D%0A%0D%0Athe price level?%0D%0AThe price level %0D%0A(Click to select)%0D%0A .%0D%0A%0D%0Aoutput?%0D%0AOutput %0D%0A(Click to select)%0D%0A
