(Figure: Dreamliners and Small Jets) Use Figure: Dreamliners and Small Jets. The combination of dreamliners and small jets at point H: A graph plots Deamliners per period on the vertical axis versus small jets per period on the horizontal axis and shows a curve. The horizontal axis ranges from 0 to 20, in increments of 20. 18 jets per period is also marked on the horizontal axis. The vertical axis has equally spaced markings at 4, 8, 12, 16, and 18, from bottom to top. A curve labeled, ?Production possibility frontier,? is concave down and decreases from (0, 18) to (20, 0). Points A, B, E, and F are marked on the curve at (0, 18), (12, 16), (18, 8), and (20, 0), respectively. A point H is marked at about (23, 8). Question 4 options: a) can be attained but would cost too much. b) cannot be attained, given the level of technology and the factors of production available. c) is attainable but would increase unemployment. d) has no meaning, since it does not relate to the preferences of consumers
