Passage Summary: Ads usually change people's minds about yogurt brands more than milk brands. However, a recent ad campaign for a specific store actually boosted milk sales more than yogurt sales.

Reasoning: No reasoning (Fact Set).

Analysis: The paradox here is the discrepancy between a general rule (yogurt is more sensitive to ads) and a specific outcome (milk sales grew more). To resolve this, we need a reason why this specific milk advertisement was uniquely effective or why the yogurt advertisement was less effective than usual. Look for an answer that provides a specific detail about the store's milk or yogurt that explains the unexpected sales jump.
