Critical Reasoning

A recent study reveals that television advertising does not significantly affect children's preferences for breakfast cereals. The study compared two groups of children. One group had watched no television, and the other group had watched average amounts of television and its advertising. Both groups strongly preferred the sugary cereals heavily advertised on television.


Which one of the following statements, if true, most weakens the argument?
(A) The preferences of children who do not watch television advertising are influenced by the preferences of children who watch the advertising.
(B) The preference for sweets is not a universal trait in human and can be influenced by environmental factors such as television advertising.
(C) Most of the children in the group that had watched television were already familiar with the advertisements for these cereals.
(D) Both groups rejected cereals low in sugar even when these cereal were heavily advertised on television.
(E) Cereal preferences of adults who watch television are known to be significantly different from the cereal preferences of adults who do not watch television.
