问题如下图：
选项：
A. 
B. 
C. 
解释：
Perez 不仅仅是cog error啊 还有emotion bias，我认为相对而言老头的问卷调查更加有效，因为他的风险程度不会发生太大变化 而另外两位都在变化，并且老头喜欢seek advice 他的问卷回答也会更认真精准！

B is correct.Perez exhibits primarily cognitive rather themotionbiases. Although risk toleranquestionnaires mfail for emotionally biaseinvials anwork best for institutioninvestors, they are generally effective for cognitive-baseinvials. 您好，李老师强化班21页，有一句话是 questionnairs对cognitive process效果更好。然后李老师又补充了一下，对于FF/II 好，对于PP/AA差一点。本着这个思路理解这道题目对吗？如果是对的，Perez是PP，Patel是都不适合。 Johnson是II 适合。哪里有问题呢？
NO.PZ201511190100000402 Perez. Johnson. B is correct. Perez exhibits primarily cognitive rather themotionbiases. Although risk toleranquestionnaires mfail for emotionally biaseinvials anwork best for institutioninvestors, they are generally effective for cognitive-baseinvials. 答案是FF，主要体现为cognitive error，其他是PP和AA，所以更适合问卷。还要具体看谁cognitive占比大吗？
NO.PZ201511190100000402 Pereze和Patel都是cognitive bias，但Perez是PP，patel是FF，且patel seeks for aices，所以选了Patel。
NO.PZ201511190100000402 Perez. Johnson. B is correct. Perez exhibits primarily cognitive rather themotionbiases. Although risk toleranquestionnaires mfail for emotionally biaseinvials anwork best for institutioninvestors, they are generally effective for cognitive-baseinvials. Johnson体现出来的应该是II这个投资者分类 也是cognitive bias体现的啊
