问题如下：
When constructing the optimal portfolios for investors with different risk preferences, the investor with the higher risk aversion is most likely to have a:(2016 mock)
选项：
A.steeper capital allocation line.
B.flatter indifference curve.
C.lower expected return.
解释：
The optimal portfolio is identified as the point at which the capital allocation line (CAL) is tangential to the investor's indifference curve. As investor risk aversion increases, the optimal portfolio slides down the CAL to a point of lower expected risk and lower expected return.何老师讲cal是单个投资者根据自己风险偏好画出来的的有效前沿和无风险资产的组合。能否帮用图画两个不同风险偏好投资者的不同有效前沿，这里有点不太明白
