2. Which of the following statements is false?
Given the spot interest rates, we can determine the price and yield of any other default-free bond.
As the coupon increases, earlier cash flows become relatively less important than later cash flows in the calculation of the present value.
 When the yield curve is flat, all zero-coupon and coupon-paying bonds will have the same yield, independent of their maturities and coupon rates.
When U.S. bond traders refer to "the yield curve," they are often referring to the coupon-paying Treasury yield curve.
 3 -Which of the following statements is false?
-We can use the law of one price to compute the price of a coupon bond from the prices of zero-coupon bonds.
-The plot of the yields of coupon bonds of different maturities is called the coupon-paying yield curve.
-It is possible to replicate the cash flows of a coupon bond using zero-coupon bonds.
- Because the coupon bond provides cash flows at different points in time, the yield to maturity of a coupon bond is the simple average of the yields of the zero-coupon bonds of equal and shorter maturities.
