case of the brilliant brother

I've a brother in particular who's a brilliant student. He got straight As for his exam. One of his friends, who happens to be from another ethnic group got somewhat similar results as my brother did. That particular friend received a thousand bucks from a minister of the same ethnic group as his. Well, good for him. A few of my brother's other friends, from yet another ethnic group, received a few thousand bucks from some race-exclusive societies; their exam results being on par with my brother. Since my brother received nothing of sorts, I gave him a thousand bucks and said something like; "you do your job, I'll do mine."

What am I?
A. A minister
B. A society

Take your pick.
