Logic Breakdown
Passage Summary: Health experts think TV makes us eat junk because the people we see on the screen are always eating junk.
Conclusion: Television viewing negatively affects the eating habits of those who watch it.
Reasoning: The food and beverages depicted or consumed on many television shows are of very low nutritional quality.
Analysis: The argument relies on a significant 'Missing Link' between what is shown on a screen and how a viewer behaves in real life. To make this argument work, one must assume that television has the power to influence viewer behavior through imitation or normalization. If viewers were completely unaffected by the dietary choices of fictional characters, the premise about low-quality TV food would be irrelevant to the conclusion about the viewers' actual habits. Look for an answer that confirms that viewers are indeed influenced by the behaviors they observe on television.

Correct Answer
B
B supplies the missing causal link: exposure to low-nutrition foods and beverages on TV increases the likelihood that viewers will consume similar items. Negation test: if exposure does not increase consumption, then the premise (what’s on TV) cannot explain the conclusion (viewers’ diets get worse), and the claim collapses.
