Problem: Given the question: Write a multi-choice question for the following article, with the given choices and 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. . Options: A What's photosynthesis? B How and why leaves change colors? C Different kinds of leaves. D How the seasons change. Answer: B How and why leaves change colors? Question:

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: "Who did this?" asked my teacher. Thirty children tried to think about not only what they had done, but also what our teacher might have found out. "Who did this?" she asked again. She never became angry, but she was this time. She held up a piece of broken glass and asked, "Who broke this window?" "Oh, oh," I thought. I was the one who broke the window. I did not do it on purpose . It was caused by a bad throw of a baseball. Why did it have to be me? If I admitted it, I would be in a lot of trouble. How would I be able to pay for a big window like that? "My father is going to get angry at me," I thought. I didn't want to raise my hand, but something much stronger than me pulled it up. "I did it," I said. Then I was silent. It was hard enough saying what I had. My teacher went to one of our bookshelves and took down a book. She then began walking towards my desk. I had never known my teacher to strike a student, but I feared she was going to start with me. "I know how you like birds," she said as she stood looking down at my face. "Here is the field guide about birds that you always _ from our school library. It is yours now. We have got a new one for the school. You will not be punished . But remember, it's only for your honesty." I couldn't believe it! I wasn't being punished and I was getting my own bird field guide, the one that I had been saving up all my money to buy.
