Part $1$: On a risk$/$return basis, rank order the following asset classes from lowest to highest based on the following data given, where E$($r$)$ is the expected return and the risk metric is the standard deviation.$$

Part $2$:$$How would this rank order change if the return for each class $[$i$.$e$.,$ the E$($r$)]$ were each reduced by a $3\%$ inflation factor?$$
