2. When preparing the initial draft for Brecksen’s review, does Grohl violate any CFA Standards?
选项：
A.No.
B.Yes, because he used Brecksen’s research reports without permission.
C.Yes, because he did not use reasonable judgment in identifying which factors were important to the analysis.
解释：
A is correct.
Grohl exercised diligence, independence, and thoroughness in analyzing the company and its competitors. Brecksen provided his research reports for Grohl’s use and using the reports as a guide was appropriate. Standard V(A) requires that members distinguish between fact and opinion in communicating investment recommendations to clients. The Standard does not apply to investment recommendations communicated to supervisors or internal investment committees.
问个一年强没有解答的问题，这个人有没有违反diligence and reasonable 啊？他在准备报告的之前，就用了old reports，没有看原始财报的数据
