Please help answer the following questions.

The yield on a one-year Treasury security is 4.2300%, and the two-year Treasury security has a 5.7100% yield. Assuming that the pure expectations theory is correct, what is the market's estimate of the one-year Treasury rate one year from now? 6.1370% 9.1694% 7.2200% 8.2308% Recall that on a one-year Treasury security the yield is 4.2300% and 5.7100% on a two-year Treasury security. Suppose the one-year security does not have a maturity risk premium, but the two-year security does and it is 0.3000%. What is the market's estimate of the one-year Treasury rate one year from now? 6.6000% 5.6100% 7.5240% 8.3820% Suppose the yield on a two-year Treasury security is 5.83%, and the yield on a five-year Treasury security is 6.20%. Assuming that the pure expectations theory is correct, what is the market's estimate of the three-year Treasury rate two years from now? 6.45% 7.10% 5.46% 6.53%
