Editor: Many candidates say that if elected they will reduce governmental intrusion into voters' lives. But voters actually elect politicians who instead promise that the government will provide assistance to solve their most pressing problems. Governmental assistance, however, costs money, and money can come only from taxes, which can be considered a form of governmental intrusion. Thus, governmental intrusion into the lives of voters will rarely be substantially reduced over time in a democracy. Which one of the following, if true, would most strengthen the editor's argument? ['Politicians who promise to do what they actually believe ought to be done are rarely elected.', 'Politicians never promise what they really intend to do once in office.', 'Politicians who win their elections usually keep their campaign promises.', 'The most common problems people have are financial problems.']
