Providing the questions beforehand means you already have an answer planned. That is called a scripted response. It means you have “acceptable” questions and “acceptable” answers already planned. If your answers are unscripted, then you have no reason to provide the questions in advance. That is reality. People can live in a imagination-land where Joe Biden is winning in polls and is likely to beat Trump at this point. That is fine. I just prefer to stick with reality.
