Question: I'm taking a test and have to guess the right answer to the question after the article. Article: We always read reports about costs of oil going up and we will think this is our most valuable material. However, water is the most valuable resource . People in the Middle East are more worried about this than oil. Maybe the next war will be about water. In the future, to control the quality and quantity , you will use different water for different usages. The water used to wash your car, water your flowers or wash your clothes doesn't need to be as clean as the water you drink. One in five people live in countries without enough fresh water and in 25 years, the number is believed to be one in every three people. Our world population is increasing. What do you suppose this will suggest for us in the future? Population control? Traditional management of the water industry has been out of date since the 1990s. When technologies develop so rapidly in the world, we have loads of information for technologies in the business world, but in the water industry we don't have any. Britain and France have already taken measures to successfully improve their water industries. All the water services in Britain have been provided by private companies since 1991. Since then, improvement has been made in the rules for their water quality and pricing. What can you do now for the future? Using water more efficiently in your house can make a great difference not only to the world but to your money. Even if you don't have to pay much now, you will when you start to pay big prices for different water usages. Question: Which is the author's suggestion for us? Options: A: Paying less money for water B: Buying more water for future use. C: Using different water for different usages. D: Using as little water as possible in cooking.
Answer: C

Question: I'm taking a test and have to guess the right answer to the question after the article. Article: Does solving a math problem give you a headache? Doyou feel nervous when you sit a math exam? For most students, math can be tough but scientists have proved that math problems can actually trigger physical pain. Scientists came to his conclusion with an in-depth experiment, which was published in the Public Library of Science One journal. They began by finding out how much participants fearmath. Those involved were asked a series of questions such as how they feel when they receive amathtextbook orwhenthey walkinto amathlesson. Based on their answers, participants were divided into groups. One group was made up of peoplewhowere particularly afraid ofmath and participantsinthe other group weremore comfortablewiththesubject. Both groups were then given either math tasks or word tasks. When a math task was going to come next, a yellow circle would appear but when a word task was soon to come, a blue squarewould beshown. Using a brain-scan machine, scientists noticed that whenever people from Group One saw ayellow circle, their brain would respond in a way similar to when their bodyis feeling pain. It waslike the pain they would fee, for example, if they burnt their hand on a hot stove. But theyreactedlessstrongly whenthey knew that they would befaced with awordtask. However, scientistssaw no strong brainresponsefrom peopleinthesecond group. Math can be difficult, and for those with high levels of mathematics-anxiety (HMA), math is associated with tension, apprehension and fear. "When you are really thinking about the math problems, your mind is racing and you are worrying about all the things that could go wrong," explained Ian Lyons from University of Chicago, US, leader of the study. "The higher a person's anxiety of a maths task, the more he activated brain regions associated with threat detection, andthe experience of pain." More interestingly, the brain activity disappeared when participants actually started dealingwiththemathtasks. "This means that it'snot that mathitself hurts; rather, the anticipation... Question: What can be concludedfrom the experiment? Options: A: Theanticipation ofmath has norelationto students' confidenceinmath. B: Moderatemathematic anxiety promotes students' academic performance. C: Effectivesolutions havebeenworked out tolower students' anxiety ofmath. D: Physical pain causedby HMA disappearsinthe process of doingmath problem.

Question: I'm taking a test and have to guess the right answer to the question after the article. Article: Mary Cassatt is one of the first great women American painters. At first her father did not want her to become an artist. But she followed her dreams and became an artist.She was born on May 22, 1844, and lived in Europe for several years as a child. Her family returned to the United States and, at age 16, Mary attended the Pennsylvania Academy of Fine Arts. Four years later she decided she couldn't learn anything fresh and practical in Philadelphia, so she returned to Europe. There she studied the skills of the masters in Rome, Seville, Antwerp, and Paris. Mary received the chance of a lifetime at the age of 33 when the famous French painter, Edgar Degas, asked her to join a group of painters that included now-famous artists like Manet and Renoir. Their style of painting is called Impressionism. They used primary colors and short brush strokes in their work. They recognized Mary 's spirit and powerful talent and invited her to exhibit in the Impressionist art shows. Mary painted what she saw: gardens, and paintings of persons , especially of mothers and children involved in everyday living. One of her paintings, "Young Mother and Two Children," was given to the White House in 1954 where it hangs today. Mary never married and, in 1877, her parents and sister moved to Europe to join her. Mary devoted much of her time to them for the next 18 years to their care. Mary painted until 1914 when her failing eyesight made it impossible to continue. She spent the later years of her life in Paris. She died in 1926 at the age of 82. Unfortunately,all her life, she refused to accept students. Question: Mary Cassatt stopping painting because of _ . Options: A: her poor eyesight B: her old age C: lack of interest D: her family
