Scientists studied 12,000 employees aged between 18 and 65.They found that those who traveled to work by car or public transport reported higher levels of stress and tiredness compared to active commuters who traveled by foot or bicycle. The negative health of public transport users increased with journey time. It is now expected that the study, from Lund University in Sweden, will encourage further investigation into the health effects of commuting and the best forms of transportation. Researcher Erik Hansson said:"Generally car and public transport users suffered more everyday stress, poorer sleep quality, exhaustion and felt that they struggled with their health compared to the active commuters." According to the Office for National Statistics, the average Briton commutes 54 minutes every day. But now the scientists claim that the advantages of daily travel, such as higher pay or housing conditions, need to be weighed against the negative health effects. Income, family background and environmental factors are other things that need to be considered. It may also have a cost effect on industry. According to a Absence and Workplace Health Survey, the U.K. economy lost 190 million working days to absence last year, with each employee taking an average of 6.5 days off sick, costing employers US$27 billion. Hansson added that findings would help to reconsider the balance between economic needs, health, and the costs of working days lost. However, researchers stress that the findings, published in the journal BMC Public Health, do not prove that commuting causes ill health and further research is needed. Question: It hasn't been proved in the study that _ . - .the balance between economic needs and health is broken - .more stay at public transport is more harmful to people - going to work by bus is more tiring than by bike - commuting causes ill health
commuting causes ill health

Read the following article and select the best answer. Article: In the second half of each year, many powerful storms are born in the tropical Atlantic and Caribbean seas. Of these, only about half a dozen becomes the strong, circling winds of 75 miles per hour or more that are called hurricanes, and several usually make their way to the coast. There they cause millions of dollars of damage, and bring death to large numbers of people. The great storms that hit the coast start as soft circling wind hundreds -- even thousands -- of miles out to sea. As they travel aimlessly over water warmed by the summer sun, they are carried westward by the southeast winds. When conditions are just right, warm, moist air flows in at the bottom of such a wind, moves upward through it and comes out at the top. In the process , the moisture in this warm air produces rain, and with it the heat is changed to energy in the form of strong winds. As the heat increases, the young hurricane begins to move in a counter-clockwise motion . The life of a hurricane is only about nine days, but it contains almost more power than we can imagine. The energy in the heat released by a hurricane's rainfall in a single day would satisfy the entire electrical needs of the United States for more than six months. Water, not wind, is the main source of death and destruction in a hurricane. A typical hurricane brings 6 to 12 inch downpours, causing sudden floods. Worst of all is the powerful movement of the sea -- the mountains of water moving toward the hurricane center. The water level rises as much as 15 feet above normal as it moves toward shore. Question: Here the word "downpour" means _ . - heavy rainfall - dangerous waves - the progress of water to the hurricane center - the increasing heat
heavy rainfall
