Press release: A comprehensive review evaluating the medical studies done up to the present time has found no reason to think that drinking coffee in normal amounts harms the coffee-drinker' s heart. So coffee drinkers can relax and enjoy their beverage -- it is safe to drink coffee. Which one of the following points to a weakness in the reasoning in the press release's argument? ['The health of the heart is not identical with the general health of the body.', 'Drinking unusually large amount of coffee could be caused by stress that itself directly harms the heart.', 'Other beverages besides coffee might contain stimulants that have some effect on the heart.', 'Coffee drinkers might choose to eat, along with their coffee, foods containing substances that harm the heart.']
