问一道题：NO.PZ201511190100000104 第4小题 [ CFA III ]

本题的解释是'The clients discussed in Statement 5 exhibit mental accounting bias because they consider their portfolio by matching its layers to goals. The clients may not have time themselves to examine the investment universe and arrive at optimal solutions, but they rely on their adviser to do this for them. Thus, they do not exhibit bounded rationality."

这段话的意思是，Statement 5中讨论的客户表现出mental accounting，因为他们通过将portfolio的layers与goal相匹配来考虑其投资组合。 这句话是说为什么选C。

第二句说，客户可能没有时间自己检查投资范围并找到最佳解决方案，但是他们靠advisor来完成这项工作。 因此，它们没有表现出bounded rationality。bounded rationality是差不多就行。客户虽然自己没有时间找最佳方案，但是他们没有妥协，而是找了投资顾问来找最佳方案。这句话是说为什么不选B。

本题是原版书习题课Reading 7第4题，建议同学再去听一下李老师的讲解。
