Passage Summary: The author believes that being smart and being wise are two different things, and in their personal life, they have never met anyone who possesses both traits simultaneously.

Reasoning: Intelligence and wisdom are distinct qualities that do not guarantee one another, and the author's personal experience suggests they are mutually exclusive in individuals.

Analysis: This is a 'Must be False' question, so we are looking for a statement that directly contradicts the rules established in the stimulus. The essayist provides two general rules—that intelligence doesn't necessitate wisdom and vice versa—and one specific observation about their own experience: every person they meet has exactly one of these traits. To find the answer that cannot be true, look for a statement that claims the essayist has met someone who is both wise and intelligent. While it is theoretically possible for such a person to exist in the world, it is impossible for the essayist to have met one according to their own testimony.
