Answer:
longer; lower
Step-by-step explanation:
bond is simply known as a debt security that entitles the issuer to pay interest (maybe semi-annually) and to repay the principal amount when the debt matures.
A coupon is simply the timely or periodic interest payments. Its rate is usually expressed as an annual rate per dollar of par value.
A bond interest rate affect its price in different ways. That is why the longer the maturity of a bond and the lower the coupon, the greater the sensitivity of the bond's price to interest rate changes.
