Homeowners aged 40 t0 50 are more likely to purchase ice cream and are more likely to purchase it in larger amounts than are members of any otherdemographic group. The popular belief that teenagers eat more ice cream than adults must, therefore, be false.
The argument is flawed primarily because the author
(A) fails to distinguish between purchasing and consuming
(B) does not supply information about homeowners in age groups other than 40 t0 50
(C) depends on popular belief rather than on documented research findings
(D) does not specify the precise amount of ice cream purchased by any demographic group
(E) discusses ice cream rather than more nutritious and healthful foods
