请问B为什么不对？我发现PP和AA都是emotional，而FF和II主要bias表现为cognitive。请问这里sophoia有什么emotional biase提现么，而Christopher有没有cognitive biase提现呢？

同学你好，这道题 B是PP， C是FF。
这道题无法通过cognitive还是emotional来判断投资者类别，但是我们可以通过PP和FF的其他特征来判断。
首先，PP是low risk tolerance (Sophia), 而FF是low to medium risk tolerance (Christopher)
其次，原版书中说PP “place a great deal of emphasis on financial security and preserving wealth rather than taking risks to grow wealth.” 这句话是说，PP非常重视财产安全，他们习惯维持现有的财富水准，而不是冒险增加财富。这和题干中对Sophia的描述相吻合。
再来看FF。原版书中说FF “tend to follow leads from their friends, colleagues, or advisers when making investment decisions.” 符合题干中对 Christopher的描述。
而且 “They often want to be in the latest, most popular investments without regard to current market conditions or the suitability of the investment to the FFs long-term goals.” 这句话是说，FF喜欢最新，最热门的投资，而不考虑当前的市场状况或投资是否符合他们的长期目标。符合题干中对 Christopher的描述。
综上， Christopher是FF.

请问老师,passive preserver 和 frieny follower 有什么不同？题目好像混在一起了。
