B. 
C. 
解释：
老师不是说BEI是对inflation的补偿，而不是实际的inflationrate吗？那THETA因该是对expected inflation的补偿而不是expectedinflation rate吧？

BEI=expecteinflation rate + uncertainty of inflation rate. 不确定性即是风险，对于风险就有风险补偿，这样的补偿通常认为是正的，所以uncertainty of inflation rate 0.因此当BEI=2.35%时, 而uncertainty of inflation rate 0，那么expecterate if inflation 小于2.35%。题目中five years 可以看作短期吗？ 如果是短期，refault free bon和 nominfault-free bon之间，相差 expecteinflation.

NO.PZ2018091701000021 表格里的3%那个通胀率是干啥用的？
NO.PZ2018091701000021 请问老师，这道题题目的表格信息有用吗？哪里知道uncertainty >0?谢谢
NO.PZ2018091701000021 能给我讲解一下吗
