Q: Read the article and select the best answer. Article: Have you ever wondered how and why a fall leaf changes color? We first have to understand what leaves are and what they do. Plants are the world's food factories. Plants take water from the ground and take CO2from the air. Plants use sunlight to turn water and CO2into glucose . Glucose is a kind of sugar. Using it as food, plants get energy and grow. Plants using sunlight to turn water and CO2into sugar is called photosynthesis . _ helps photosynthesis. It gives plants their green color. As summer ends and autumn comes, the days get shorter and shorter, and trees "know" to begin getting ready for winter. During winter, there is not enough light or water for photosynthesis. Trees rest during this time and live on the food they store during the summer. They begin to shut down their food -- making factories. As the green chlorophyII disappears from the leaves, we begin to see yellow and orange leaves. These colors have been in the leaves all the time. We just can't see them in the summer, because they are covered up by the green chlorophyII. The bright reds and purples we see in leaves are made mostly in autumn. In some trees, glucose is caught in the leaves after photosynthesis stops. Sunlight and the cool nights of autumn turn this glucose into a red color. The brown color of trees is made from waste left in the leaves. It is mixture of all these things. It makes the beautiful leaves during autumn. . Question: Plants use sunlight to turn _ into sugar. Options: A: water and chlorophyII B: water and CO 2 C: CO 2and glucose D: water and glucose

Q: Read the article and select the best answer. Article: Everyone knows that chickens lay eggs . Most people know that all the other birds do as well. But have you ever thought about other animals that lay eggs? They include bees, snakes and some sea animals. When a mother lays eggs, many more babies can be born at once, or in a few days, because there is very little development inside the parent. Animals that do not lay eggs often have fewer babies. Animals lay many eggs because other animals may eat the babies. However, even though some of their babies are eaten, they will still have some more to continue their family. Some animals that lay eggs do not take care of their young. Turtles come onto the beach and dig holes. Then they put their eggs in the sand and leave. A turtle mother can lay as many as 150 eggs. When the babies come out of the eggs, they must find their own way to the ocean. They must learn how to live on their own. Many young turtles get eaten by other animals. Most eggs have an outside shell that keeps the growing animal inside safe. The egg shell also keeps the young animal from drying out. After the animal is fully developed, it comes out of the egg. The animal grows bigger and bigger. Then it can have its own young. Question: Why do animals lay many eggs? Options: A: Because other animals may eat their babies. B: Because they use their eggs for food. C: Because they want to have fewer babies. D: Because they want to eat their babies.
