问题如下图：
选项：
A. 
B. 
C. 
解释：
我觉得这个有点奇怪，未来deflation所以未来预期利率走低，所以现在看yield curve向下，我怎么觉得是A，
NO.PZ2018123101000044 问题如下 Tyo anher assistant are scussing the term structure theory. Tyo’s assistant asks, \"Assuming investors require liquity premiums, how ca yielcurve slope wnwar Whes this imply about forwarrates?\"Tyo answers, -Even if investors require compensation for holng longer-term bon, the yielcurve cslope wnwar— for example, if there is expectation of severe flation. Regarng forwarrates, it chelpful to unrstanyielcurve namicalculating implieforwarrates.-With respeto this scussion of yielcurves, Tyo is most likely scussing whiterm structure theory? Pure expectations theory Locexpectations theory Liquity preferentheory C is correct.考点Liquity PreferenTheory, SegmenteMarket Theory anPreferreHabitTheory解析流动性偏好理论表明流动性溢价存在以弥补投资者在长期放贷时面临的额外利率风险，流动性溢价随着期限的增加而增加。根据Tyo的描述，他所说的为Liquity preferentheory。 liquity preferentheory中的额forwarrate是upwar biaseof expectefuture spot rate~原因是其中包含了liquity premium。与题目中的wnwarcurve之间有什么关系？怎么理解
NO.PZ2018123101000044 对flation有点疑问，望解惑，感谢！ 按照这题目答案的，flation预期会导致利率走低。但是flation不就是资产价格（Price）低迷，这样回报率应该变高啊？ 很多文献里flation ten to put upwarpressure on rerates.所以一直有个印象，觉得这题假设有点反常规，还是我参照物错了？
B为什么不行呢， 也是long term加risk premium
我也觉得是A阿啊阿啊阿啊
