问题如下：
1. When downloading the model from Greenfield Financial Corporation, does Acertado violate any CFA Institute Standards of Practice and Professional Conduct?
选项：
A.No.
B.Yes, because he does not have written permission from Boswin.
C.Yes, because he does not have permission from Greenfield Financial Corporation.
解释：
C is correct.
Boswin, as an employee, developed the model on behalf of Greenfield. Therefore, Greenfield, not Boswin, is the owner of the model. Acertado violates Standard IV(A) Duties to Employers: Loyalty when he downloads the model without proper written permission from Greenfield Financial. Acertado is misappropriating employer assets.
请问用model的这个分析师题干里面没有说ta不是Greenfield Financial Corporation的分析师啊。。如果是同一家公司，为什么要得到许可呢？
