Homeowners aged 40 to 50 are more likely to purchase ice cream and are more likely to purchase it in larger amounts than are members of any other demographic group. The popular belief that teenagers eat more ice cream than adults must, ttherefore, be false. The argument is flawed primarily because the author ['does not supply information about homeowners in age groups other than 40 to 50', 'does not specify the precise amount of ice cream purchased by any demographic group', 'fails to distinguish between purchasing and consuming', 'discusses ice cream rather than more nutritious and healthful foods']
