But there is another factor that can cause your heart problems more immediately: the air you breathe. Previous studies have linked high exposure to environmental pollution to an increased risk of heart problem, but two analyses now show that poor air quality can lead to heart attack or stroke within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA) considers to be of "moderate" quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure. The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.

Read the following article and select the best answer. Article: The centenary of the birth of William Faulkner, one of the great modern novelists, was celebrated in September 1997. Faulkner wrote about the southern states of the United States of America where he grew up, and where his family had an important part to play in the history of that region. His work became a touchstone for insights into the troubled issues of southern American identity, race relations, and the family interrelationships of the old time southern gentry . Faulkner was born in New Albany, Mississippi on September 25, 1897. Despite his interest in writing, he left Oxford High School, Mississippi, without graduating. After World War I, he entered the University of Mississippi as a special student, a right to study which was granted to retired soldiers, although Faulkner had only finished training with the Air Force in Canada, and not entered combat . Faulkner began to write poems, a verse play, short stories and finished his first novel Sartoris in 1928. His fiction was centered for 14 of the 19 novels published during his lifetime in a fictional region called Yoknapatawpha County. The name is said to come from the Indian Chickasaw word meaning split land. In December 1950, Faulkner was awarded the Nobel Prize for Literature. When he accepted it in Stockholm, his speech emphasized that he wished to continue writing, but in a positive way that affirmed the power of humanity to prevail over adverse circumstances. As he said in his speech, he still felt that, despite the threat of nuclear war then hanging over the world, the central concern of the writer should be "the problems of the human heart in conflict with itself". He wanted the tensions and problems that he had cast the spotlight on in the southern states of America to be resolved by the life-affirming attitudes and action of his characters. Like playwright Tennessee Williams, Faulkner was a major voice who spoke for the troubled heart of the southern states of America. His achievement is all the more remarkable because, as a schoolboy, he was... Question: Which of the following statements about Tennessee William is true? - Both Tennessee William and William Faulkner are playwrights. - Tennessee William was a major voice who spoke for the troubled people in southern America. - Like Faulkner, he once won Nobel Prize for literature. - Tennessee William had to pursue his writing career through difficult times.

Read the following article and select the best answer. Article: It can be hard to encourage families of preschoolers to turn off the TV,but there are plenty of highquality shows that promote learning and positive relationships rather than violence,researchers noted. "Although clearly kids watch too much,what's more worrying is that they watch poor quality shows," said Dr Christakis,the lead researcher on the new study from the University of Washington in Seattle.His former survey of parents of threeto fiveyearold children showed the kids often watched violent cartoons and movies that are "totally inappropriate". For their study,he and his colleagues randomly divide 565 preschoolers into two groups.In one group,parents recorded notes about kids' normal TV viewing,without receiving any guidelines to reduce or change those habits.In the other group,researchers made visits and calls and sent monthly newsletters encouraging parents to replace violent TV with educational programming.After six and 12 months,parents reported their kid's angry,aggressive or anxious behaviors on a questionnaire.At both time points,children in the TV intervention program had slightly fewer problems than those in the comparison group.Boys in lowincome families seemed to benefit most from the change in programming,the researchers found. "The point is,this is something that is as effective as other things we do to try to guide behavior in children,and it's fairly simple," Christakis said. Another study published in Pediatrics found the more TV kids and teens watched,the more likely they were to have a crime or other problems in society.Children may imitate violence they see--or more time in front of the TV could simply mean less communication with peers and families,and worse performance in school. The American Academy of Pediatrics recommends kids watch no more than one to two hours of highquality programming each day.Researchers agreed parents should be mindful of what exactly their young kids are watching on TV as well."It's not just about turning the TV off,it's about changing the channel,"... Question: What is the positive effect of highquality TV shows on kids? - Good learning results and relationships. - Being affected by violence. - Spending less time on TV programming. - Encouraging them to turn on the TV.
