Problem 2A: Bruno is a landowner and Angela is a farmer who pays a share of her grain output to Bruno for the use of the land. The figure shows Angela and Bruno's feasible frontier, Angela's biological survival constraint, and her reservation indifference curve. Angela's biological survival constraint Angela's reservation indifference curve 12- (c) ( b ) . Feasible frontier: Angela and Bruno combined Bushels of grain (d) 2.5-+ .Z: Angela's reservation option 24 Angela's hours of free time If Angela does not work, she receives a ration of 2.5 bushels from the government. Which of the following statements is correct? The economically feasible set can be an empty set. Angela's reservation indifference curve may not necessarily go through Z. Angela's reservation indifference curve can be below her biological survival constraint. The economically feasible set is the area between Angela's biological survival constraint and the feasible frontier
