a) Malaysia is a major producer in chickens and beef. The production combinations for chickens and beef are shown in the table below. (i) Draw a fully labeled graph (including labeling all the points A to F, X-axis for chickens and Y-axis for beef) of Malaysia's Production Possibility Frontier (PPF). (2 marks) (ii) Calculate the opportunity cost of producing more beef as Malaysia moves from combinations A to B, B to C, C to D and D to E. (4 marks) (iii) Briefly explain the opportunity cost of producing more beef in (ii) above. (2 marks) (iv) Suppose there is a new farming technique in cattle production, leading to more beef produced. Explain, with the aid of a PPF diagram, what would happen to the shape of the PPF
