You observe the following term structure:

Effective Annual YTM

$1-$year zero$-$coupon bond $6\mathrm{.}7\%$

$2-$year zero$-$coupon bond $6\mathrm{.}8$

$3-$year zero$-$coupon bond $6\mathrm{.}9$

$4-$year zero$-$coupon bond $7\mathrm{.}0$

Required:

If you believe that the term structure next year will be the same as today$$s$,$ calculate the return on $($i$)$ the $1-$year zero and $($ii$)$ the $4-$year zero.

Which bond provides a greater expected $1-$year return?
