问题如下：
Which of the following statements about amplification through network structure is not correct?
选项：
A.Network structure can amplify and propagate shocks. B.Symmetrical information plays an important amplifying role in standard theories of systemic risk. C.Cyber shocks can derive solvency shocks. D.Financial networks structured for resiliency to market risk and for liquidity sharing may be vulnerable to cyber shocks.解释：
B is correct
Asymmetric information plays an important amplifying role in standard theories of systemic risk.非对称信息是导致 amplification 的原因，因为比如新闻或者谣言会使人们为了保证自己的本金安全而从没有受影响的金融机构撤离资金。所以B选项描述是错误的。
我有点没理解，这题B到底在说什么？为什么不对？
