Article: Science has told us too much about the moon that it is fairly easy to imagine what it would be like to get there. It is certainly not a friendly place. Since there is no air or water, there can be no life of any kind. There is not much variety of scenery either. For mile after mile there are only flat plains of dust with mountains around them. Above, the sun and stars shine in the black sky. If you step out of the mountain shadow, it means moving from the severe cold into intense heat. These extreme temperatures break rocks away from the surface of the mountains. The moon is also a very silent world, for sound waves can only travel through air. But beyond the broken horizon, you see a friendly sight. Our earth is shining more brightly than the stars. From this distance, it looks like an immense blue, green and brown ball. Question: The best title for the passage is _ . Yes or no, is the answer "The Moon"?
Yes

Article: For years scientists have been worried about the effects of air pollution on the earth's natural conditions. Some believe the air inside many houses may be more dangerous than the air outside. It may be one hundred times worse. Indoor air pollution can cause a person to feel tired, to suffer eye pain, headache and other problems. Some pollutants can cause breathing disorders, diseases of blood and even cancer. Most scientists agree that every modern house has some kind of indoor pollution. People have paid more attention to the problem now. It is true that when builders began making houses and offices they did not waste energy. To do this they build buildings that limited the flow of air between inside and outside. They also began using man-made building materials. These materials are now known to let out harmful gases. As the problem became more serious, scientists began searching for a way to deal with it. They discovered a natural pollution control system for building--green plants. Scientists do not really know how plants control air pollution. They believe that a plant's leaves absorb or take in the pollutants. In exchange the plant lets out oxygen through its leaves and tiny organizations on its roots. Scientists suggest that all buildings should have one large plant or several small plants inside for every nine square meters of space. Studies of different plants show that each absorbs different chemicals. So the most effective way to clean the air is to use different kinds of plants. Having green plants inside your house can make it a prettier and healthier place. Question: The reason why we should use different kinds of plants to clean the air is that Yes or no, is the answer "plants can absorb all kinds of harmful indoor chemicals"?
(Answer)
No

Ques: Article: Is carrying a few extra pounds into your senior years healthy? Advice has been mixed. Now, two studies published this month attempt to better define the ideal weight for fitness and longevity for adults over age 60. The main point is that you don't need to worry about being slightly overweight, as long as that extra weight is maintained at a consistent level. However, being very overweight is detrimental to health, and exercising to lose body fat and to gain muscle mass is always beneficial. Determining the ideal weight for older people has been a pursuit, with researchers looking for what weight is not too thin, but not too fat. Studies have suggested that being slightly overweight can be protective. For example, a 2001 study by researchers at Yale University found that moderately overweight senior adults with a body mass index (BMI) of 27 -- two points higher than the BMI of 25 that defines being overweight -- lived longer than seniors who were either thinner or heavier. There's a fine line here, though, because carrying extra pounds is a risk factor for many types of cancer and other diseases. And, according to the researchers behind the two new studies, the general public has misinterpreted the Yale findings to mean that being very overweight is healthy. One new study, published this month in the American Journal of Epidemiology by researchers at The Ohio State University in Columbus, found that seniors who maintained a stable, slightly overweight status survived most probably over the 16 years surveyed. Those seniors who had a so-called healthy weight going into the study (a BMI between 18.5 and 25) and who gained weight, but stayed below BMI 25, had a slight possibility of surviving over the study period. People in the obese group, with a BMI higher than 35 and who continued to gain weight, faced the worst among all the groups in the study. But next-to-last were normal-weight people who lost weight, but this was likely because they... Question: As for the 2001 study, the general public wrongly think that _ . Yes or no, is the answer "it is healthy and protective for people to be very overweight"?
Ans: No

Ques: Article: Way back in 1662,John Evelyn,a brilliant Englishman known for his detailed diaries,wrote About disastrous effects of coal-burning on the city of London .In it,he described an infernal scene of smog.air filled with "Columns and Clouds of Smoke''given out by small industries and residences that burned coal for fuel. I found the description in the 2003 book When Smoke Ran like Water,by epidemiologist and environmental advocator Devra Davis.In it,Davis looks back at several historic pollution events and their disastrous effect on human human health-and at how these phenomena were often Ignored or even actively covered up by then people in charge at that time. As Davis points out,John Evelyn was ahead of his time when writing about how London's polluted air affected the well-being of its residents.It wasn't until nearly 300 years later,after what became well-known as the Great Smog of 1952,that the government began to address the problem in a systematic way. For four days.Between December 5th"and 9th",due to all accident of the weather pattern,the city was buried in a heavy fog .People were still burning coal for fuel,and low-grade coal at that time, because 0f wartime condition.A temperature inversion trapped the smoke from the city's fires, creating a black cloud in which people could barely find their way down the most familiar streets Some tried to protect themselves,but most people simply went about their business But l952's fog was far worse than any other in memory.In the same week of the previous year, 1852 people had died in London;inl952,that number was 4703 And the deaths didn't stop when the weather changed and the fog lifted.Davis and her colleagues analyzed data from the next several months and found that about 13000 more people died between December and March than one would have predicted from historical averages Many of them died of pneumonia .The government, she writes.Tried to blame a bad flu season.Her detailed analysis found that explanation simply did not pan out. Davis... Question: The passage is written to Yes or no, is the answer "warn people of the danger from air pollution"?
