Dietician: "The French Paradox" refers to the unusual concurrence in the population of France of a low incidence of heart disease and a diet high in fat. The most likely explanation is that the French consume a high quantity of red wine, which mitigates the ill effects of the fat they eat. So North Americans, with nearly the highest rate of heart disease in the world, should take a cue from the French: if you want to be healthier without cutting fat intake, drink more red wine. Which one of the following statements, if true, most seriously undermines the conclusion of the dietician's argument? ['A greater intake of red wine among North Americans would likely lead to a higher incidence of liver problems and other illnesses.', 'Many other regions have much lower rates of heart disease than France, though their populations consume even less red wine than do North Americans.', 'French men consume as much red wine as French women do, yet French men have a higher rate of heart disease than do French women.', 'All evidence suggests that the healthiest way to decrease the chance of heart disease is to exercise and keep a diet low in fat.']
