解释：
■ Module C should be chosen for Goal 1, Module B
should be chosen for Goal 2, and Module D should be chosen for Goal 3.
■ The module that should be selected for each goal is the one that offers the highest return given the time horizon
and required probability of success. The module that should be selected for
each goal is the one that offers the highest return given the time horizon
and required probability of success. For Goal 1, which has a time horizon of five
years and a required probability of success of 85%, Module C should be chosen
because its 4.4% expected return is higher than the expected returns of all the
other modules. Similarly, for Goal 2, which has a time horizon of 10 years and
a required probability of success of 99%, Module B should be chosen because its
2.2% expected return is higher than the expected returns of all the other
modules. Finally, for Goal 3, which has a time horizon of 25 years and a
required probability of success of 75%, Module D should be chosen because its
7.5% expected return is higher than the expected returns of all the other
modules.
以后这种根据个人不同的goal选portfolio的，是不是只要选对应年份和概率下收益率最大的那个就可以了？不会出现哪怕选了收益率最大的那个portfolio也无法满足目标的情况么？
比如这个题目如果说25年后要如何如何，比如asset要达到多少，不需要实际计算一下么？
