Suppose net investment income is N I I = 100, the international asset position is A = 3000, the international liability position is L = 4000, and the rate of return is 5 percent, 5" = 0.05. (a) (3 marks) Economist John Green, a strong advocate of the dark matter hypothesis, believes that A is not accurately recorded. Calculate the amount of dark matter and the \"true\" international asset position, which we will denote TA, consistent with Green's view. (b) (3 marks) Financial analyst Nadia Gonzalez does not believe in the dark matter hy pothesis. Instead, she believes that A is accurately measured. In her view 5 percent is actually the rate of return on assets TA = 0.05, and the rate of return on the coun- try's international liabilities, \"FL, is different. Find the value of TL consistent with Gonzalez's view
