没太明白B为什么错了，难道线性的Portfolios不能模拟出分布吗？
NO.PZ2016062402000034问题如下 Whione of the following statements about Monte Carlo simulation is false? Monte Carlo simulation cusewith a lognormstribution. Monte Carlo simulation cgenerate stributions for portfolios thcontain only linepositions. One awbaof Monte Carlo simulation is thit is computationally very intensive. Assuming the unrlying process is normal, the stanrerror resulting from Monte Carlo simulation is inversely relateto the square root of the number of trials. MC simulations account for options. The first step is to simulate the process of the risk factor. The seconstep prices the option, whiproperly accounts for nonlinearity. a和矛盾吗，正太分布的区别
