CR : Television Advertising .

[sac3433]

The source is LSAT CR :

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.

The OA is : A


Is this question a sort of specific pattern in which 2 groups are talked about / compared & the correct option should talk about the group in question ??? can I simply cancel out C because it doesn't mention anything about the group(the group in question) that didn't view the advertising ???

there is no such thing as CR on the LSAT, and we do not answer LSAT questions here because LSAT questions are too different from GMAT questions to be worth your while studying..
