问题如下：
With respect to rational and irrational investment decisions, the efficient market hypothesis requires:
选项：
A.only that the market is rational.
B.that all investors make rational decisions.
C.that some investors make irrational decisions.
解释：
A is correct.
The efficient market hypothesis and asset-pricing models only require that the market is rational. Behavioral finance is used to explain some of the market anomalies as irrational decisions.
b、c为什么都错呢

Market ration和 investor ration有什么区别？
