The researchers used a national long-term survey of adolescent health to investigate the relationship between media use and depression. They based their findings on more than four thousand adolescents who were not depressed when the survey began in 2000. As part of the survey, the young people were asked how many hours of television or videos they watched daily. They were also asked how often they played computer games and listened to the radio. Media use totaled an average of five and one-half hours a day. More than two hours of that was spent watching TV. Seven years later, in 2007, more than seven percent of the young people had signs of depression. The average age at that time was twenty-one. The researchers say they did not find any such relationship with the use of other media such as movies, video games or radio, etc. But the study did find that every extra hour of television meant an eight percent increase in the chances of developing signs of depression. Young men were more likely than young women to develop depression given the same amount of media use. The study didn't explore if watching TV causes depression. But one possibility is that it was taking time away from activities that could help prevent depression. Last December, the journal Social Indicators Research published a study of activities that help lead to happy lives. Sociologists from theprefix = st1 /UniversityofMarylandfound that people who describe themselves as happy spend less time watching television than unhappy people. The study found that happy people are more likely to he socially active, to read, attend religious services and to vote. The best title for this passage should be _ . A) Teens, Television and Depression B) Men Develop Depression Easier than Women C) Media Use is Harmful to Adolescents D) Take Great care of Teenager's depression

Q: The European Union announced plans on Tuesday to temporar-ily ban the use of animal cloning for food production, while allowing imports of food derived from the offspring of clones from the United States and elsewhere. The report from the European Commission followed a call by EU lawmakers in July for a total ban on food derived from cloned animals and their traditionally bred offspring, citing ethical concerns over the industrial production of cloned meat. The Commission said a temporary five-year EU ban on cloning for food production was justified on animal welfare grounds, but said banning imports of food from the offspring of clones was unnecessary and would disrupt global trade. "Food from cloned animals is safe. In fact, the scientific opinion is that it cannot be differentiated in any way from food normally bred animals. The issue is animal welfare," EU Health and Consumer Commissioner John Dalli told reporters. Food derived from the offspring of clones presents no such animal welfare issues, and banning its sale and import would be impossible because the origin is untraceable, Dalli said. "Such a prohibition would lead to a ban of imports of any food of animal origin (meat, milk and processed products)from third countries allowing the cloning technique," the report said. "We're not going to regulate for the world," Dalli added. But animal welfare groups criticized the Commission's decision, saying it had bowed to pressure from third countries. "We do not accept the Commission's position that it would be impossible to enforce a ban that includes the offspring of cloned animals, as (other) meat traceability systems are already in place," said Sonja Van Tichelen, director of the Eurogroup for Animals. Which of the following is TRUE according to the passage? A) The ban is permanent. B) The imports of food from the offspring of clones are not banned. C) Animal welfare groups support the ban. D) The ban has been put into effect.
A: B

Experts do not really know when people began keeping fish as pets. But they say that people have been interested in fish for thousands of years. Some say the ancient Sumerians were the first civilization to keep fish in ponds more than four thousand years ago. The Chinese kept and studied carp and goldfish more than one thousand years ago. The ancient Romans kept eels as pets. And the Greek philosopher Aristotle made what is believed to be the first known study of sea life, including sharks and dolphins. Keeping fish at home in small water tanks called _ is extremely popular today. And everyone seems to enjoy visiting huge public aquariums that have opened around the world. By the middle of the eighteen hundreds, science had shown that plants, fish and other sea creatures could survive together under water. So it was no longer necessary to change the water in a tank for the fish to live there. This led to the building of the first public aquariums. The first aquariums opened in London, England in 1853. in the next fifteen years, other aquariums opened in Europe and the United States. By 1928, there were about forty-five public aquariums. The Monterey Bay Aquarium has been recognized as the first aquarium in the United States and it shows visitors the underwater life in the bay. The Georgia Aquarium opening in 2005 says it is the largest in the world. It has more than one hundred thousand sea animals in thirty million liters of water including two whale sharks---the world's largest fish. Another aquarium re-opened in 2005 in Camden, New Jersey. The Adventure Aquarium first opened in 1992. It spent about fifty million dollars expanding its building and improving its exhibits. Aquariums provide the public with many chances to experience life under the sea. They can be found in most areas of the world. People might even want to start an aquarium at home and join the millions of people around the world who keep fish as pets. The passage is written mainly _ . A) to tell people the importance of keeping fish as pets B) to explain why people want to visit aquariums C) to let people know the development of the aquariums D) to describe different aquariums
