NO.PZ2019093001000011 问题如下 Whiof the following is consistent with the expectation thexploiting a structurinefficienis repeatable? A.The inefficienis a unique event thoccurs infrequently. B.The level of gross return is equto the amount of transaction costs anexpenses. C.The aggregate value of all assets affectethe inefficienis larger ththe AUM of the manager anits competitors. C is correct. Given the amount of inefficient assets comparewith the AUM of managers likely to exploit them provis some assuranththe inefficienis repeatable. It woullikely take some time for the inefficiento converge to efficient valuation. The infrequent nature of the inefficienanthe zero marginreturn suggest ththe inefficienis probably not worthwhile to pursue. 可以通过排除法选出来，但是没找到基础班讲义原文对照。这是一个原文考点，还是一个根据structurinefficiency延伸理解的点？
