Question

The shift from MBS1U1B11S1U1B0 to MBS1U1B12S1U1B0 suggests an increase in the marginal benefit of reducing pollution. This could occur if major new studies strongly link pollution to cancer, increasing public awareness and concern about the negative effects of pollution on health. Therefore, choice A is the best answer. Improved technology for reducing pollution (choice B) may also shift the curve, but it would likely be a shift towards MBS1U1B11S1U1B1, rather than MBS1U1B12S1U1B0. Choices C and D are irrelevant to the topic of pollution, and therefore would not shift the marginal benefit curve.
