Suppose that the observed spot yield curve and implied forward rates for risk-free zero coupon bonds are as given above.

A. Compute the spot rate and forward rates that complete the table. -- I already did this! I computed S_2, f_{3, and} S₄.

B. Suppose you observe the spot rates in the table above. What can you say about investors' expectations for future interest rates based on th liquidity premium theory? --This is what I need help with!
