不理解为什么是c呢，whole life insurance不是longevity risk 吧问一道题：NO.PZ2020011901000024 [ FRM I ]
NO.PZ2020011901000024 问题如下 Whtwo activities of life insurancompanies have opposite exposures to longevity risk?

Annuities have longevity risk (i.e., the risk thpolicyholrs will live longer thexpecte. 我对于题目的理解有些问题，不应该是相对于longevity risk 相反的风险是哪两个吗？但是看了之前同学的提问，看老师的回答都是以下中相互是相反的？

Annuities have longevity risk (i.e., the risk thpolicyholrs will live longer thexpecte. 这道题问哪两种对longevity risk有相反的敞口，是不是说哪两种活动会担心死的早的风险？而whole life 和年金，因为担心死的早，所以就入选了，这样理解对吗？
这道题问的是跟longevity风险相反的exposure是什么，longevity是怕人活的久了赔付风险高，那个whole life insuran是希望人活的久，不希望过早死亡而进行赔付，这个敞口跟longevity是相反的，我可以理解，但是annuities have longevity risk 这不就是说明跟longevity有着相同的exposure吗？并不是相反的exposure呀？
老师好，这道题题目能够翻译一下问的是什么吗？我理解的是问哪种保险有longevity risk，所以应该是只有annuities，不应该有whole life insurance呀？
