问题如下：
An individual investor’s ability to take risk is higher than average level. His willingness to take risk is lower than average level. How about his risk tolerance, comparing with the average level?选项：
A.Higher than average level B.Lower than average level C.Same with the average level解释：
When assigning an overall risk tolerance, the prudent approach is to use the lower of ability to take risk and willingness to take risk.是不是只有ability or willingness 中有一个低了--那就是low risk tolerance
When assigning an overall risk tolerance, the prudent approach is to use the lower of ability to take risk and willingness to take risk.
有点不太明白这个lower of 需要怎么衡量
