Answer:
The bon's real rate of return is 1.39%.
As we know the inflation rate behave same as the bond yield because the bond yield includes the inflation impact.
In case of if there is a increase in the inflation in future. I will not buy this bond, because the price of the bond will fall and as percentage increases the present value of the cash flows also decreases which is the basis used for pricing the bons.
In case of if there is a decrease in the inflation in future, I will buy this bond, because the price of the bond will rise and as percentage decreases the present value of the cash flows also increases which is the basis used for pricing the bons.

Real Rate of return = Nominal rate - Inflation rate
As Bond yield is nominal rate
Real rate of return = 5.78% - 4.39% = 1.39%
