Since the indifference curve has a slope of zero at the point (20, 70), it indicates that Nancy's utility does not change with an increase in her second midterm score from 70, which would only be the case if her best score is what matters (as in Professor Goodheart's class). In Professor Stern's class, where the worst score counts, her utility would increase with an increase in her lower score.
