Question: Read the following article and select the best answer. Article: PALO ALTO, California----"Switching off the television may help prevent children from getting fatter---- even if they do not change their diet or increase the amount they exercise," US researchers said last week. A study of 192 third and fourth graders, generally aged eight and nine, found that children who cut the number of hours spent watching television gained nearly two pounds(0.9kg) less over a one-year period than those who did not change their television diet. "The findings are important because they show that weight loss can only be the result of a reduction in television viewing and not any other activity," said Thomas Robinson, a pediatrician at Stanford University. "American children spend an average of more than four hours per day watching television and videos or playing video games, and rates of childhood being very fat have doubled over the past 20 years," Robinson said. In the study, presented this week to the Pediatric Academic Societies' annual meeting in San Francisco, the researchers persuaded about 100 of the students to reduce their television viewing by one-quarter to one-third. Children watching fewer hours of television showed a significantly smaller increase in waist size and had less body fat than other students who continued their normal television viewing, even though neither group ate a special diet or took part in any extra exercise. "One explanation for the weight loss could be the children unstuck to the television may simply have been moving around more and burning off calories," Robinson said. "Another reason might be due to eating fewer meals in front of the television. Some studies have suggested that eating in front of the TV encourages people to eat more," Robinson said. Question: The time children spend on TV viewing every day is suggested to be about - six hours - eight hours - three hours - one hour
Answer: one hour

Question: Read the following article and select the best answer. Article: Great white sharks! Just hearing that name _ . In reality, these big fish have more to fear from us than we do from them. For many years, people killed countless great white sharks in the waters around the United States. But thanks to conservation efforts, great whites are making a comeback in the U.S. Two recent studies show that the population of these sharks is rising along the east and west coast. Why is the growing population of a killer fish something to celebrate? "When you fish too many of them, you start to lose balance in the environment," says shark researcher Tobey Curtis. As the biggest killer, sharks help keep the populations of fish, seals, and other creatures they eat from growing too large. In spite of their importance, great white sharks had long been hunted for their meat and their fins . Then, in 1997, the U.S. government passed a law that didn't allow the hunting of great whites. Afterwards, the numbers of these sharks in the U.S. waters started to increase. The law wasn't the only thing that has helped great whites. Conservationists have also played a part in the sharks' comeback. The research group OCEARCH is using a method called tagging to help change people's attitudes about great white. They let the public follow each shark as it travels the world's oceans. OCEARCH also gives each tagged shark a name to help people form a closer connection with the big fish. The group's most well-known shark is named Katharine. She was tagged last year near Cape Cod, Massachusetts. Since then, thousands of people have tracked Katharine's movements on Twitter and the OCEARCH website. This helps people see sharks in a new way. Chris Fischer, the founder of OCEARCH believes learning to appreciate great whites will encourage people to do more to protect them. Question: The main purpose of the passage is to _ . - introduce an experiment result - make an advertisement for OCEARCH - remind us that big killers are dying out - inform us that great whites are making a comeback
Answer:
inform us that great whites are making a comeback
