(This forum seems to favor several small, simple questions over one big, complex question. Hence the multiple threads with similar titles.)In this room, there are five people who/that are White, seven African American, and two Asian.
(Ignoring the interchangeability of "who" and "that" for now....)
Would dropping "who/that are" cause major ungrammaticality, or add/delete subtle meaning to the sentence?
