问题如下：
Which of the following statements is not an intention of disclosure in the Standard on Referral Fees?
选项：
A.Clients or employers could evaluate the full cost of the services.
B.Clients or employers could request discounted service fees.
C.Clients or employers could evaluate any partiality shown in any recommendation of services.
解释：
B is correct.
A and C are the two primary purposes for disclosing the referral fees to clients under Standard VI(C) Referral Fees.
从题目角度，是可以排除A和C的，但是B选项还是有点意思。
为什么说discount 可以不披露？ 教材中原文类似的语句吗？
