Two Polls Were Conducted to Determine How Much Support There

Two polls were conducted to determine how much support there was for public funding of private schools. However, the results from the two polls were contradictory. One poll asked whether "students should attend private school at public expense". The other poll asked "How much do you support providing parents with the option of sending their children to the school of their choice - either public, private or parochial - rather than only to the school to which they are assigned?" Explain why the wording of the questions may have affected the results.
