Theamount of pollution abatement is plotted horizontally, with amountsrising from Q 1 to Q 4. The vertical axis is labeled society’s M Band M C of pollution abatement. The graph shows two rising curveslabeled M C 1 and M C 2 and two falling curves labeled M B 1 and MB 2. M B 2 lies above M B 1 and M C 2 lies to the right of M C 1.The falling curves start at two different points on the top leftand end at two different points on the bottom right. The risingcurves start at two different points on the bottom left and end attwo different points on the top right. M B 1 and M C 1 intersect atQ 1. M B 2 and M C 1 intersect at Q 2. M B 1 and M C 2 intersect atQ 3. M B 2 and M C 2 intersect at Q 4.
Refer to the diagram. From society's perspective, ifMB1 and MC2 are relevant,
