Which one of the following statements, if true, most weakens

Answer choices

  1. Correct69% picked this

    The preferences of children who do not watch television advertising are influenced by the preferences of children

    Why this is right

    This states that the preferences of children who don't watch TV advertising are influenced by those who do, suggesting that TV ads either directly or indirectly affect all children's preferences. This establishes a causal link between TV advertising and preferences, counter to the conclusion. It offers a different explanation for why TV-kids and non-TV kids both prefer sweet cereals. It's not just because they inherently prefer the sweet cereal. It's because ads brainwashed the TV-kids, and then those kids brainwashed the non-TV kids.

    Skill tested: Weaken · how this choice captures the argument's function is the move to repeat next time.

  2. Weakens8% picked this

    The preference for sweets is not a universal trait in humans, and can be influenced by environmental factors

    This proposes that preference for sweets, which can be shaped by TV advertising, isn’t a universal trait, introducing a potential role for ads but lacks direct evidence or scope regarding specific cereal preferences in this context.

  3. No Impact10% picked this

    Most of the children in the group that had watched television were already familiar with the

    This mentions familiarity with ads among TV-watching children without directly affecting non-TV watchers' similar preferences, thus not offering alternate reasoning for shared preferences.

  4. Strengthens12% picked this

    Both groups rejected cereals low in sugar even when these cereals were heavily

    This reveals both groups rejected low-sugar cereals despite advertising, supporting the claim that advertising doesn’t influence preferences for sugary cereals, reinforcing the conclusion.

  5. Weakens (Slightly Relevant)1% picked this

    Cereal preferences of adults who watch television are known to be significantly different from the cereal preferences of adults

    This hints at a pattern where adult TV watchers' preferences differ from non-watchers, implying TV influence. However, it concerns adults and diverts from the specifics of the children's study.
