Leaves are the world's food factories. Plants take water from the ground through their roots and take CO2from the air. Plants use sunlight to turn water and CO2into glucose , a kind of sugar. Plants use it as food for energy and growing. A chemical called _ in the leaves gives plants their green colour. 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 sunlight or water. 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 chlorophyll disappears from the leaves, we begin to see yellow and orange leaves. The bright reds and purples we see in leaves are made mostly in autumn. In some trees, like maples , sunlight and the cool nights of autumn turn the glucose in the leaves into a red colour. And we can enjoy the beautiful red leaves during autumn.

Instead of going to camp last summer, Zach decided to walk 668 miles from Atlanta to Washington, D.C. He hoped more people would help homeless kids. His journey to help others began six years ago. Zach walked from his home in Tampa to Tallahassee. Then, in 2008, Zach Bonner went on a 270-mile walk from Tallahassee to Atlanta. In 2010, he did it again, from Tampa to Los Angeles. Last summer, Zach traveled 12 miles every day on foot. Along the way, he collected more than 1000 letters about homeless children. He hoped to give the letters to President Obama. Zach says he wants his walk to make a difference. More than 1 million children in the U.S. have nowhere to live. During his journey, Zach spent 24 hours with some homeless children so he could learn the difficulties they face. When Zach walked the last mile of his long journey, more than 500 supporters, including 300 homeless kids, joined Zach. They went with him down the National Mall. "It was a long walk," Zach says, "but it was meaningful." Although the journey is difficult and tiring, Zach won't give up. "When homeless kids get tired of being homeless, they don't get to stop.

Question: Read the following article and select the best answer. Article: Some scientists say that animals in the ocean are increasingly threatened by noise pollution caused by human beings. The noise that affects sea animals comes from a number of human activities. Such noises are added to natural sounds. These sounds include the breaking of ice fields, underwater earthquakes, and sounds made by animals themselves. Decibels measured in water are different from those measured on land. A noise of one hundred and twenty decibels on land caused pain to human ears. In water, a decibel level of one hundred and ninety-five would have the same effect. Some scientists have planned to set a noise limit of one hundred and twenty decibels in oceans. They have found that noises at that level can frighten and confuse whales. A team of American and Canadian scientists discovered that loud noises can seriously hurt some animals. The research team found that powerful underwater explosions were causing whales in the area to lose their hearing. This seriously affected the whales' ability to exchange information and find their way. Some of the whales even died. The explosions had caused their ears to bleed and become infected. Many researchers whose work depends on ocean sounds disagree to a limit of one hundred and twenty decibels. They say such a limit would mean an end to important industrial and scientific research. Scientists do not know how much and what kinds of noises are harmful to ocean animals. However, many scientists suspect that noise is a greater danger than they believed. They want to stop noises from harming creatures in the ocean. Question: As to the influence of noises on whales, which of the following statements is TRUE? - They are deaf because of noises. - Noises at a certain level may hurt them. - They are easily confused by noises. - Noises will limit their ability to reproduce.
Answer: Noises at a certain level may hurt them.
