Questions don't exist.
There are also two types of questions. They are both requests for an an answer. But, one is based on the lack of knowledge of the asker, the other is demonstration of the lack of knowledge of the person being asked.
The difference inbetween the two is if there is an answer or not. As an example, John says, "Green is the same thing as blue". Fred comes along and asks, "But they appear different, so how can they be the same?". John can then answer, "They are both colors." In this case (assuming that John was not lying), Fred had a lack of knowledge. Once given that knowledge, the question is invalid, as there is no lack of knowledge. Even until now the question was nothing but a reperesentation of a lack of knowdege. But that is not something that has standing, per se.
Had John actually though they were the same color, he would now see Fred's point, and concede that his original statement was false. In which case his original statement had no standing, and thus the question has no standing, being it was asked on a statement that had no standing to begin with.
