This puzzle asks you to find the single category linking five clues: Clouds, Parasols, Tinted glass, Dark curtains, and The Moon during some eclipses. The answer is Things that block sunlight. Each clue is a concrete example of a broader collection. The answer is the set label that every row belongs to without stretching the meaning. With only "Clouds", many categories could fit. Hold your first guess and watch what clue 2 eliminates. "Clouds" and "Parasols" must share one repeatable link — not a coincidence between two words. By clue 3 ("Tinted glass"), "Things that block sunlight" should explain all three without bending meanings. "Dark curtains" strengthens "Things that block sunlight" rather than opening a new theory. The final clue ("The Moon during some eclipses") confirms "Things that block sunlight" — if it still fits naturally, the category is locked.
