请问这题的考点是什么？
NO.PZ2016082405000030 analyst is stuing the C sprecurve for establishecompany. The 1-, 3- an5-yesprea are 400 bps, 200 bps, an150 bps, respectively. Whiof the following interpretations of the ta is most likely correfor the shape of the fault stribution? fault stribution Near-Term Slope Upwarsloping flslope wnwarsloping steep slope Upwarsloping steep slope wnwarsloping flslope C The C sprea incate a wnwarsloping sprecurve. Note ththe cumulative stribution of fault is always increasing regaress of the slope of the sprecurve. In aition, sinthe short-term probability of fault is relatively high, the slope in the neterm of the fault stribution function is relatively steep. 题目也没有说是问cumulative啊，我理解撑了marginfault stribution不行么

老师，这个题目为啥是看累计分布？题目也没说啊
