The 8-year spot interest rate (the longer of the spot rates, or the n-year rate) is 5.71% and the 2-year (k-year) forward rate expected (n - k) years from now has been estimated to be 5.99%. What is the other spot rate you need to know to find the forward rate given above using the pure expectations theory? Round to the nearest 0.01%. E.g., if your answer is 5.785%, record it as 5.79
