What are the problems with the following survey questions?

        • Do you agree that Americans should be more concerned with conserving fuel and reducing pollution from auto emissions?

        • Do you favor reducing the outrageous number of administrators in the federal government?

        • Most people believe that politicians are overpaid. Do you agree?

I thought the problem was, they were simply all closed questions, what am I missing?
