When worms pass the leaves, their waste can help to make the soil rich, from which the plants use to get their nutrition. The plants grow and provide food for animals. When the animals eat the plants, their waste goes back into the soil. It's a perfect cycle. But at the Elephant Conservation Centre in Lampang, Northern Thailand, they are using elephant waste for something more--to make 100% natural, beautiful color1ful paper products! 100 years ago over 100,000 elephants in prefix = st1 /Thailandworked on farms, building sites and even in the army. However, only 6,000 remain there today because of advances in technology that have made elephants' old word less necessary. Elephants are doing new jobs now, including entertaining tourists by painting and playing football, and now by helping in the paper making industry. And their keepers, called Mahouts, can earn a living for their families and help their elephants by using elephant waste, also called "dung" to make beautiful, natural, paper products without any bad smell. Every day an adult elephant eats about 200kg of plants like bamboo, grass and watermelon seeds. His body system breaks the plants into 50kg of fibers, which can produce 115 sheets of fibrous paper. The first step to make this special natural paper is to collect the fiber rich "dung" from the elephant. The next step is to wash it and boil it for five hours to kill bacteria. (The water the use in this process is reused to water plans at the Centre, which, in turn, feed the elephants). After it's boiled, they cut fibers up. During the cutting process, they add in the desired color1 of the paper. For the fourth step, they take the mixture and make balls of 300g. Each ball is then speeds lightly over bamboo frames to dry into one large sheet of paper. After a few hours in the sun, the sheets are dry enough to remove. The result is a wonderful, 100% natural, recycled paper. People around the world are getting... Question: What is the famous product mentioned in the passage? Options: A: Paper. B: Dung . C: Fibers.

I told him that I couldn't do it. He asked, "Why not?" I paused, and then I said, "Because I'm educable mentally retarded ." He came from behind his desk and looked at me. "Don't ever say that again. Someone's opinion of you does not have to become your reality," he said. It was a very special moment for me. Doctors said that I was educable mentally retarded in the fifth grade, and I was put back into the fourth grade. When I was in the eighth grade, I failed again. But Mr Washington changed my life. This person always gave students the feeling that he had high expectations of them, and then all of the students did their best to live up to what those expectations were. He often said, "You have greatness within you." One day, I caught up with him in the parking place and said, "Mr Washington, is there greatness within me, sir?" He said, "Yes, Mr Brown." "But what about the fact that I failed in English, math and history? What about that, sir? I'm slower than most kids." "It doesn't matter. It just means that you have to work harder. Your grades don't determine who you are or what you can produce in your life." "I want to buy my mother a house." "It is possible, Mr Brown. You can do that." And he turned to walk away. "Mr Washington?" "What do you want now?" "Uh, I'm the one, sir. One day you're going to hear my name. I'm the one, sir." School was a real struggle for me. Mr Washington put many demands on me. He made me believe that I could do it. At the end of that year, I was on the honor roll for the first time in my life. Years later, I produced five programs on public television. When one of my programs was shown on the educational television channel, I had some friends call him. I was sitting by the phone waiting when he called me. He said, "May I speak to Mr Brown, please?" "Oh, Mr Washington, is that you?" "Yes, it's me. You... Question: What happened to the author at last? Options: A: He entered a good university. B: He earned much honor. C: He got a good job.
