Question: I'm taking a test and have to guess the right answer to the question after the article. Article: As people in Beijing and northern China struggle with severe air pollution this winter,the toxic air is also making life hard for plants and even food crops of China. "in the last 50 years there has been a 1 6-fold increase in ozone pollution"in the Beijing area,said Hanqin Tian of Auburn University in Alabama,who studies the effects of China's pollution and climate change on plants. Ozone is particularly harmful to plants because it damages the pores on leaves,called stomata,which plants use to regulate how much water evaporates from the leaves.That,in turn,affectS how much water a plant must take up through its roots.Changes in water uptake by plants have been documented in other parts of the world,including the United States,as having major impacts on regional groundwater and surface water supplies. In studies of the long-term productivity of plants,Hanqin Tian and some of his colleagues show that ozone pollution,along with climate change,has been lowering plant productivity in China,which reduces the amount of carbon and other pollutants that the plants Can absorb to fight all the emissions from the burning offossil fuels. The worst effects on plants are likely to be in areas where the growing pollution problem is just fairly new, said Arthur Chappelka, also a plant researcher at Auburn University.Some plants are more resistant to pollutants than others,he said,and the plants that are living today in long-polluted urban areas are likely to be only those that are very pollution tolerant. Away from the cities, however, where crops are necded to feed China's yast population, the effeets of the growing pollution on crops is a significant concern. "In some ways it affects the crop production and food securiy of China,"said Hanqin Tian."Air quality is really important for human health, plants and ecosystem and sustainability." The problem is bound to get worse as China continues to develop economically, he said, and so he and other researchers continue to urge the Chinese government to take action to reduce... Question: Which of the following statement does Hanqin Tian support? Options: A: Ozone pollution has increased 1 6 times in the past 30 years. B: Ozone pollution has lowered plant productivity alone. C: Plants can take in a large amount of carbon and other pollutants. D: The toxic air has few effects on food supply in China.
Answer: C

Question: I'm taking a test and have to guess the right answer to the question after the article. Article: If you thought taking vitamins would reduce the risk of lung cancer, think again. Researchers who studied 77,721 people said on Friday that people who took too much vitamin E,especially smokers,had a small but higher risk of developing lung cancer. They tracked the subjects'use of multi-vitamins,vitamin C and vitamin E to see if it offered protection from lung cancer.But they found that none of the vitamins was tied to a reduced risk. "If you could find some sort of magic pill--a pill you could take once a day to decrease your risk--that would be wonderful.But unfortunately.we didn't find that in our study,"lead researcher Christopher Slatore,of the University of Washington Seattle,said. The subjects of the study were followed for four years,and 521 developed lung cancer,the majority of them smokers or former smokers,Slatore's team reported in the American Journal of Respiratory and Critical Care Medicine. Among those in the study who developed lung cancer, the researchers saw a small increased risk related with vitamin E supplements in addition to the expected connections to smoking,family history and age. This added up to a 28 percent increased risk of developing lung cancer for those taking 400 mg of vitamin E supplements daily for 10 years,the researchers said. "For people--especially smokers--I suggest that they not take vitamin E(as a supplement) unless they have a very strong reason to take it." Slatore said. The idea that vitamin supplements are healthful,or at least not harmful.comes from the desire of many people to match the benefits of a healthful diet with a convenient pill,Tim Byers of the University of Colorado School of Medicine.wrote in an essay. Question: The writer thinks the statement"taking vitamins would reduce the risk of lung cancer,is_. Options: A: wrong B: right C: doubtful D: possible
Answer: A

Question: I'm taking a test and have to guess the right answer to the question after the article. Article: Once there was a man who lied to eat mangoes. One day he decided to get the sweetest mango from the very top of the tree. Mangoes which are exposed to the sun the most are the sweetest. So he climbed up to the top, where the branches were thin. He managed to pick up a few sweet reddish fruits, but, in an attempt to climb down, he slipped and started falling towards the ground. Fortunately, he caught the branch as he was falling and remained helplessly hanging on the tree. Then he started to call nearby villagers for help. They immediately came with a ladder and sticks, but could do little to help him. Then after some time one calm and thoughtful person arrived - a well-known sage who lived in a simple hut nearby. People were very curious to see what he would do, as he was famous in solving many people's problems in the area and sometimes very complicated ones. He was silent for a minute and then picked up a stone and threw it at the hanging man. Everybody was surprised. The hanging mango lover started to shout: What are you doing?! Are you crazy? Do you want me to break my neck?" The sage was silent. Then he took another stone and threw it at the man. The man was very angry: "If I could just come down, I would show you!" That's what everybody wanted - that he came down. But how? Now everybody was tense, as to what would happen next! Some wanted to chastise the sage, but they didn't. The sage picked another stone and threw it again at the man, even more forcefully. Now the man on the tree was enraged and developed a great determination to come down and take revenge. He then used all his skill and strength and somehow reached the branches which were safe to start going down. And he made it! Everybody was amazed. However, the rescued man found the sage gone. He stood there, realizing that the man really sed him because he induced him to try his best and save himself. "I should be thankful and not angry." Question: What does the story imply? Options: A: Anger saves one's life. B: Wisdom does count. C: Skill and strength count. D: Anger is the biggest enemy.
