Passage Summary: People generally like colors they can see clearly. While infants can see bright colors well, they struggle with subtle shades, and this difference is reflected in the fact that bright toys for babies sell better than muted ones.

Reasoning: The passage establishes that all people prefer colors they can easily distinguish; it then notes that while infants struggle with subtle shades, they see bright colors easily, and that bright infant toys outsell those in subtle shades.

Analysis: In a 'Most Strongly Supported' task, we must treat the premises as absolute facts and see where they lead when combined. We know that 'all people' prefer colors they can distinguish easily, and we are told that infants specifically struggle with subtle shades that adults find easier to navigate. Since infants do not buy their own toys, the fact that bright toys sell better suggests that the buyers—presumably adults—are either choosing based on the infant's known preferences or that the 'all people' rule applies to the buyers' own perceptions. Look for an answer that connects the visual limitations of infants or the general preference rule to the actual sales data provided.
