1. Currently, the yield-to-maturity yield on 10-year US Treasury bonds with zero coupons is 0.66% (0.0066 < 1%). You buy these bonds at $936 per bond and plan to keep them as a "safe" long-term investment (eg 4-5 years). The face value is $1,000 at maturity.
   1. Let's assume that starting next year, interest rates start to increase at a rate of 1% per year (1.6% in 2021, 2.6% in 2022, etc.) and the yields of these bonds follow a similar upward trend. 
   2. What will the prices of 10-year bonds be from 2021 to 2030? 
   3. What will your rate of return be if you sell your bonds in 2023?
   4. Assume that interest rates do not change much, but the average inflation rate over the next 10 years is 2.5% per year. 
   5. What will be your real rate of return if you hold the bonds until maturity?
   6. Do you still want to invest in these bonds? Why or why not?
