解释：
为什么B错？这个量化的记录不应该保存吗？说删就删，不留备份是不是不太合适？

B看了报告，觉得量化模型不重要，而且表现出他对这个模型不熟知，然后G本来想保留模型，但是B电话打断了。这些信息难道都是误导信息？怎么就能判断他删除模型是做了充分研究和判断呢？
Brecksen是看了G同学的报告，说同意G同学的观点。请问题干中哪里写了Brecksen用top-wn方法得出他自己的观点的？如果没有自己推导，又说看不同multi-factors模型就同意G的观点，那么也违反了R吧？
committee对量化模型很满意可以看出量化模型很重要啊，所以应该保留recor？
老师，这道题那个同学认为不重要在哪看出来的啊，为啥他觉得不重要就删了啊
