[Q]: Article: ATLANTA, Georgia--- Alternative medicine --- including yoga, meditation, herbs and the Atkins diet ---appears to be growing in popularity in the United States, perhaps because of dissatisfaction with conventional care, the government said Thursday. More than a third of American adults used such practices in 2002, according to the government survey of 31,000 people, the largest study on non-conventional medical approaches in the United States.If prayer is included, about 62 percent of U.S.adults used some form of alternative medicine. The results seem to indicate more people are turning to alternative medicine, though the 2002 survey could not be directly compared to previous studies because of differences in size and survey methods, health officials said. The top alternative therapies included prayer (43 percent of adults) , natural products(19 percent), meditation(8 percent)and diets such as Atkins, Ornish, or the Zone (4 percent).More people also are using natural products such as herbs or enzymes to treat chronic or recurring pain , said Richard Nahin of the National Center for Complementary and Alternative Medicine, part of the National Institutes of Health. "Many conditions are not easily treated with conventional medicine," Nahin sad. "It may be the public that is turning to complementary and alternative medicine because it's not getting relief from conventional medicine." But people should not be turning away from conventional treatments that are proven safe, said Dr.Stephen Straus, director of the alternative medicine center. "People are making individual decisions to neglect those therapies and we have concerns about those choices," he said. Health officials said they were concerned that 13 percent of those surveyed said they turned to alternative medicine because regular medicine is too expensive. "It needs to be explored ---we need to find out whether they were insured or not" Nahin said. Health officials also were surprised that 6.6 percent of those surveyed used the supplement kava , which has been associated with liver disease. "People make the assumption that because something is natural that it's safe" Nahin said. "But a number of studies have shown that natural products can be unsafe when used inappropriately or with other drugs." He said people considering using alternative medicine should consult their doctor first.
Answer: Alternative medicine becomes more popular
[A]: Which can be used as the proper title for the passage?

[Q]: 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.
Answer: Some factors cause indoor air pollution.

[Q]: Article: In a time when a dangerous number of people are overweight, many people seem to have forgotten the most important way to keep healthy and slim---exercise. And as a new study carried out on mice in the lab has shown, exercise done early in life can reward you in your adult years. A team of researchers at the University of California studied the effects of early exercise on adult physical activity, body mass and eating. They found that early-age exercise in mice has positive effects on adult levels of voluntary exercise in addition to reducing body mass. "These results may have an effect on the importance of regular physical education in elementary and middle schools," said Theodore Garland, a professor of biology, who led the research project. "If kids exercise regularly through their school years, then they may be more likely to exercise as adults, which could have far-reaching positive effects on human health and well-being." Although the positive effects of early-life exercise lasted for only one week, it is important to note that one week in the life of a mouse is the same as about nine months for humans. "Our results suggest that any positive effects of early-life exercise on adult exercise will need to be kept up if they are to be long-lasting." His team of researchers found, too, that all mice that had access to early exercise were lighter in weight than non-exercised mice. Garland explained that, in general, exercise will stimulate appetite sooner or later. However, it is possible that certain types of exercise, done for certain periods of time or at certain light levels, might not _ appetite much, if at all, at least in some individuals. "If we could understand what sorts of exercise these might be, then we might be able to tailor exercise recommendations in a way that would bring the benefits of exercise without increase in appetite, leading to a better chance of weight loss," he said.
