It describes chlorophyll as a dominant pigment that absorbs sunlight and hides other colors, then shows how shorter days and cooler nights gradually stop chlorophyll production. Once green fades, carotenoids reveal yellows and oranges, while anthocyanins are produced in fall using sugars.

The truth is that the colors were hiding inside the leaf the whole time, waiting for their turn. A summer leaf is like a busy green factory, packed with a chemical called chlorophyll that soaks up sunlight and makes food for the tree. There is so much chlorophyll that it drowns out every other color, the way a bright flashlight hides the stars.  \nThat green flashlight, it turns out, cannot stay on forever. As autumn arrives, the days grow shorter and the nights grow longer and cooler, and the tree senses the change like an alarm clock. It slowly shuts the food factory down and stops making chlorophyll, so the green fades away week by week. And once the green is gone, the colors that were waiting backstage finally step into the spotlight.  \nThe first performers to appear are the yellows and oranges, made by pigments called carotenoids. Believe it or not, these were tucked inside the leaf all summer long, hidden behind the green, the same pigments that make carrots orange and bananas yellow. When the chlorophyll disappears, they are simply uncovered, like furniture found under a sheet you finally pulled off. So that golden maple in your yard did not turn yellow overnight; it was quietly yellow underneath the entire time.  \nThe reds and purples play by a completely different rule. Unlike the carotenoids, pigments called anthocyanins are not hiding in summer at all; the tree actually makes them fresh in the fall from leftover sugar trapped in the leaves. That is why a string of sunny days and crisp, cool nights can paint a forest in the brightest reds, while a warm, cloudy autumn leaves the colors dull. So the weather you complain about is secretly the artist deciding how bold the show will be.  \nAfter the grand color show, the leaf has one last trick before it lets go. The tree grows a thin, corky wall where the leaf stem meets the branch, quietly cutting off the water and cementing the leaf loose. One gust of wind, and down it drifts, joining the crunchy pile you love to jump in on a Halloween afternoon. And here is the strangest part of the whole story: the fiery reds and golds were never new colors at all, only secrets a tree keeps until the light is just right.  \nWhy Leaves Change Color  \nName:  \n\n| Solve each problem.\u003Cbr>Use the article to answer the question.\u003Cbr>1) What is the main idea of the first paragraph?\u003Cbr>A.
