问题如下：
Exhibit 1 shows Nguyen’s yield curve assumptions implied by the spot rates.
Note: Par and spot rates are based on annual-coupon sovereign bonds.
Nguyen states that she has a two-year investment horizon and will purchase a three-year fixed-rate Bond Z as part of a strategy to ride the yield curve.
Nguyen is most likely making which of the following assumptions?
选项：
A.Bond Z will be held to maturity
B.The three-year forward curve is above the spot curve
C.Future spot rates do not accurately reflect future inflation
解释：
B is correct.
考点：考察Riding the yield curve策略成功需要的条件
解析：使用的策略是riding the yield curve，为了使得该策略成功，要求收益率曲线是向上倾的。而当Forward rate高于Spot rate时，就说明收益率曲线是向上倾斜的。因此B选择正确。
根据表格中给的spot rate，收益率曲线本来就是向上倾斜的，为什么还要再假设f在s上面呢？
