Short5 blue6 waves7 scatter8 more9 than10 long11 red12 waves13, so14 daytime15 skies16 look17 blue18 to19 our20 eyes21. Too many.\n\nNeed exactly 20. Maybe: \"Sunlight scatters in air; short blue wavelengths scatter more than long red wavelengths, so daytime skies appear blue.\" Count: Sunlight1 scatters2 in3 air4 short5 blue6 wavelengths7 scatter8 more9 than10 long11 red12 wavelengths13 so14 daytime15 skies16 appear17 blue18. Need 2 more. \"to eyes\" 19 to20 eyes21? Wait if add \"to eyes\" gives 20? Current 18, add \"to eyes\" 20? Let's recount with punctuation not word: Sunlight1 scatters2 in3 air; short4 blue5 wavelengths6 scatter7 more8 than9 long10 red11 wavelengths,12 so13 daytime14 skies15 appear16 blue17. Need 3 words: \"to our eyes\" -> 20? 17+3=20. Sentence: \"Sunlight scatters in air; short blue wavelengths scatter more than long red wavelengths, so daytime skies appear blue to our eyes.\" Count: Sunlight1 scatters2 in3 air; short4 blue5 wavelengths6 scatter7 more8 than9 long10 red11 wavelengths,12 so13 daytime14 skies15 appear16 blue17 to18 our19 eyes20. Good. Need exactly 20 words. Check hyphen none. Punctuation attached doesn't create word. It's explanatory. final only that. Ensure no quotes.\n"
