Respuesta :

There is a difference in the change of pronounce used. The best (and probably correct answer) is the first sentence: However, when the entire residence staff listened to our argument again, they became convinced that the system wasn't fair. The pronounce 'they' refer to the collective term of 'entire residence staff'.
