Article: Sometimes you'll hear people say that you can't love others until you love yourself. Sometimes you'll hear people say that you can't expect someone else to love you until you love yourself. Either way, you've got to love yourself first and this can be tricky. Sure we all know that we're the apple of our parent's eyes, and that our Grandmas think we're great talents and our Uncle Roberts think that we will go to the Olympics. But sometimes it's a lot harder to think such nice thoughts about ourselves. If you find that believing in yourself is a challenge. It is time you built a positive self-image and learn to love yourself. Self-image is your own mind's picture of yourself. This image includes the way you look, the way you act, the way you talk and the way you think. Interestingly, our self-images are often quite different from the images others hold about us. Unfortunately, most of these images are more negative than they should be. Thus changing the way you think about yourself is the key to changing your self-image and your whole world. The best way to defeat a passive self-image is to step back and decide to stress your successes. That is, make a list of you need to, but write down all of the great things you do every day. Don't allow doubts to occur in it. It very well might be that you are experiencing a negative self-image because you can't move past one flaw or weakness that you see about yourself. Well, roll up your sleeves and make a change of it as your primary task. If you think you're silly because you aren't good at math, find a tutor. If you think you're weak because you can't run a mile, get to the track and practice. If you think you're dull because you think it doesn't mean it's true. The best way to get rid of a negative self-image is to realize that your image is far from objective, and to actively convince yourself of your positive qualities. Changing the way you think and working on those you need to improve will go a long way towards promoting a positive self-image. When you can pat... Question: What is the passage mainly about?

Article: The food we eat seems to have profound effects on our health. Although science has made big steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that 80 percent of all human illness are connected with diet and 40 percent of cancer is connected with the diet. Therefore, that food is connected with illness is not a new discovery. In 1940's scientists realized that nitrates , which are often used to keep color1 of meat, and other additives caused cancer. However these additives remain in our food and it becomes more difficult to know which additives are helpful or harmful. Farmers sometimes give drugs to animals not because the animals are ill but because they want to sell the animals at higher prices. For example, farmers try hard to make animals grow big so that they can sell the big animals for more money. Although the Food and Drug Administration has tried again and again to control farmers to do so, farmers go on doing this. Question: What are nitrates used for? Yes or no, is the answer "They keep the color1 of meat."?
(Answer)
No

Ques: Article: Scientists are closely concerned with the structure of buildings and with the quality of building materials. The World health Organization (WHO) observes that the introduction of air conditioning and energy conservation measures have been accompanied by growing problems of indoor air quality. Some pollutants arise from insulation products, some from moving cars, and others from modern housing materials. As many Europeans spend up to 90% of their lives in buildings, the health effects of the indoor climate are very important. Some construction materials, including fiberboard, insulation foams and certain glues for man-made wood floor boards, for example, give out organic products such as formaldehyde . Heat and humidity increase the release of formaldehyde and the gas seriously harms the eyes. Paint, lacquer, etc. can also release dangerous gas into indoor air. Construction materials can cause serious damage, especially when they contain asbestos . Asbestos is naturally present in rock formations worldwide. It belongs to a family of mineral substances made up of solid, non-combustible fiber. These properties make asbestos a highly sought-after construction material. As early as 1931, however, public health officers in the prefix = st1 /United Kingdomrevealed the connection between breathing in asbestos dust and such diseases as lung cancer. The land on which a building is sited may also contribute to pollution. Some kinds of granite or similar rocks contain traces of radium. As it breaks down, this naturally radioactive element produces some kind of radioactive gas that goes through tiny cracks in walls, floors and building materials, and makes its way into the building and the rooms. The better the homes are insulated, the more is the dangerous gas in indoor air. The main effect of this dangerous gas on health is to increase the risk of lung cancer. Question: Why should we be careful about the land on which a building is to be sited? Yes or no, is the answer "To make sure that the land contains no radioactive material."?
Ans: No

Question: Article: In October, Ubayd Steed, a sixth grader in Philadelphia, Pennsylvania, was taking a math test when he noticed a classmate looking at his paper. " I quickly turned my paper over," he said. Later that day, Ubayd met the cheater and told him not to do it again. Unfortunately, Ubayd' s experience is not unusual. Whether it's kids copying class -mates' answers during tests or friends sharing homework, cheating happens in schools every day. Experts say the behavior starts in the lower grades. Surveys show that one in three elementary students admits to cheating. Jacob Harder, a fourth grader in Ware, Massachusetts, has had classmates ask to copy his homework. "I wouldn't want to just tell them the answers," he says. So instead, he explains the task and encourages his classmates to do it themselves. But many kids find it hard to say no. "l hear from kids all the time, ' I can' t say no to a friend,'" says Eric Anderman, a professor at The Ohio State University who studies cheating in school. He says it' s important to say no from the start. "Then you _ , and the other kid gets the message," he says. Plus, he points out, "a real friend is not going to disown you because he or she couldn't copy your math homework." The kids doing the copying may feel they need to cheat to be accepted by other kids. And some students may cheat simply because others do. "If you' re in an atmosphere where cheating is common, you may think that if you don' t cheat, you' re at a disadvantage," says Michael Josephson, founder of the Josephson Institute of Ethics. But Josephson says students shouldn't think that way. "There are a lot of things kids do," he says. "You have to decide what kind of person you' re going to be." When school becomes too challenging, Anderman suggests going to the teacher rather than relying on the work of others. "It' s good to ask for help," he says. Question: Ubayd' s experience serves as a(n) _ Yes or no, is the answer "introduction"?
Answer:
No
