问题如下图：
选项：
A. 
B. 
C. 
D. 
解释：
B的解释很牵强，that contain only linear positions是portfolio的定语从句，指的是这个组合只有线性头寸，MCS可以为只有线性头寸的组合产生分布，这样看来没说错啊。而不是解释里面的“只能为线性组合产生分布”，only是在从句里的，不等同于MCS only can generate distribution for portfolio......
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
