Article: A new study suggests that the more teenagers watch television, the more likely they are to develop depression as young adults.But the extent to how much TV may be to blame is a question that the study leaves unanswered. The researchers used a national long-term survey of adolescent health to look into the relationship between media use and depression.They based their findings on more than 4,000 adolescents who were not depressed when the survey began in 1995. 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 5 and one half hours a day.More than 2 hours of that was spent watching TV. 7 years later, in 2002, more than 7 percent of the young people had signs of depression.The average age at that time was 21. Brian Primack at the University of Pittsburgh medical school was the lead author of the new study.He says every extra hour of television meant an 8 percent increase in the chances of developing signs of depression. The researchers say they did not find any such relationship with the use of other media such as movies, video games or radio.But the study did find that young men were more likely than young women to develop depression given the same amount of media use. Doctor Primack says the study did not explore why watching TV causes depression.But one possibility, he says, is that it may take time away from activities that could help prevent depression, like sports and socializing. It might also affect sleep, he says, and that could have an influence. The study was just published in the Archives of General Psychiatry. In December, the journal Social Indicators Research published a study of activities that help lead to happy lives.Sociologists from the University of Maryland found 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 be...

Read the following article and select the best answer. Article: Nowadays, the food we eat seems to have great effects on our health. Although science has made enormous 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 perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well, especially cancer of the colon. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures. That food is related to illness is not a new discovery. In 1945, about 68 years ago, government researchers realized that nitrates, commonly used to preserve color in meats, and other food additives, caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to beef and living animals, and because of this, penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical purposes, but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration (FDA) has tried repeatedly to control these procedures, the practices continue. Question: What are nitrates used for? - They preserve flavor in packaged foods. - They preserve the color of meats. - They are the objects of research. - They cause the animals to become fatter.
(A).
They preserve the color of meats.

The bride and her father arrived in a new black American sports car. Her father looked nervous and uncomfortable in front of the cameras. The bride wore a silk wedding dress. She smiled nervously at the waiting photographers and went to a room on the first floor where she met her future husband for the very first time. Carla Germaine and Greg Cordell were the winners of a radio station's competition. The aim of the competition was to find two strangers prepared to marry without having met each other. Miss Germaine,23, is a model. Mr. Cordell, 27, is a TV salesman. They were among the two hundred people who entered for a peculiar "experiment" organized by BMRB radio in Birmingham,England. Greg and Carla were among eight finalists who were interviewed live on radio. They took a lie detector test and the station also spoke to their friends and family about their personalities. The competition judges included an astrologer who declared that they were suited. The couple celebrated their wedding with a wedding breakfast and a party for 100 guests in the evening, but not everyone shared their joy. Miss Germaine's mother looked anxious throughout the wedding and Mr. Cordell's parents are reported to be less than delighted. Organizations, including the marriage guidance service Relate, have criticized the marriage. As one person put it, "We have enough problems getting young people to take marriage seriously without this. Marriage should always be about love."
