Q. My proofreader says that the verb needs to be singular in this caption, but that reads as incorrect to me. Can you instruct me or give me bragging rights (not that I would ever brag, of course)? “Ann Smith, one of seven alumni who talks about leadership.”
A. Those seven alumni who talk about leadership are plural, so the verb should be plural as well. Ann Smith will have to get her own verb. (But please be nice to your proofreader!)
