Politician: Those economists who claim that consumer price increases have averaged less than 3 percent over the last year are mistaken. They clearly have not shopped anywhere recently. Gasoline is up 10 percent over the last year; my auto insurance, 12 percent; newspapers, 15 percent; propane, 13 percent; bread, 50 percent. The reasoning in the politician's argument is most vulnerable to criticism on the grounds that the argument ['attempts to persuade by making an emotional appeal', 'fails to show that the economists mentioned are not experts in the area of consumer prices', 'uses evidence drawn from a small sample that may well be unrepresentative', 'impugns the character of the economists rather than addressing their arguments']
