Read the following article and select the best answer. Article: It's believed that a bad job is worse than no job at all. I'm not convinced, but here's the argument anyway. Researchers at the Australian National University in Canberra compared the mental health of more than 7,000 working age Australians. They found that those with jobs had an average score of 75 in a test of mental well-being. Jobless people averaged 68.5. If you remained unemployed a long term it lowered your mental health score by 1.1 points. But getting a poor quality job lowered your score ever further - by 5.6 points. The results suggest that having a bad job may be worse for your mental health than having no job at all. So what is a bad job? According to the study it's one where you have little control over decision-making; the job makes heavy demands on you; there's no job security; and you feel underpaid. My advice would be that if a reasonable offer of employment comes along, seize it. If you discover that you don't like the work, that's OK. You've given it your best shot and discovered that this type of work isn't for you. In my own case my first job was as a trainee social worker. I very quickly learned that I was too young, too inexperienced and innocent to become a social worker. I cut my losses and tried something else. I worked as an economic researcher - and was miserable. These experiences taught me that I was a person. But from my short time as a trainee social worker I had discovered an ability for interviewing people and writing reports. That led finally to journalism. So take up that first job offer and find out about the world of work. If you realize the job isn't what you expected, that's OK. Look around for something else. So I disagree that a bad job is worse than no work at all. Remember, it's always easier to find a job if you are already in work. Question: From the writer's experience, we could learn that _ . - a poor quality job in hand is worse than no jobs at all - long-term unemployment got him a mental score of 75 - you will find another more easily if you stick to a job - if a bad job offer comes to you, give it up immediately
you will find another more easily if you stick to a job

Read the following article and select the best answer. Article: The term "smog" was first used in London during the early 1900's to describe the combination of smoke and fog. What we typically call " smog" today is a mixture of pollutants but is primarily made up of ground-level ozone . Ozone can be beneficial or harmful depending on where it stays. The ozone staying high above the Earth protects human health and the environment, but ground-level ozone is responsible for the choking, coughing, and painful eyes associated with smog. The ozone in smog also prevents plants growth and can cause widespread damage to crops and forest. Major smog occurrences often are linked to heavy motor vehicle traffic, high temperatures, sunshine, and calm winds. Weather and geography affect the position and severity of smog. Because temperature regulates the length of time it takes for smog to form, smog can form faster and be more severe on a hot and sunny day. When warm air stays near the ground instead of rising and winds are calm, smog may stay trapped over your city for days. As traffic and other sources add more pollutants to the air, the smog gets worse. Smog is often more severe away from the pollution sources because the chemical reactions that cause smog occur in the atmosphere while the reacting chemicals are being moved by the wind. Smog is a visible example of air pollution. You can look into the distance during the day to see how much smog there is in the air. In addition, most cities measure the concentrations of pollutants in the air and report the results to the public. Environmental Protection Agency sets national standards for pollutants. Areas that fail to meet the standards for at least one air pollutant are called "nonattainment areas. " New measures are being taken by local governments across the country to reduce air pollution in nonattainment areas. These include: banning charcoal barbecues and wood burning in stoves or fireplaces when pollution levels are high; developing programs to encourage carpooling and voluntary "ozone actions" ;... Question: According to the passage, ground-level ozone can _ . - damage the environment - benefit human health - protect crops and forest - limit the spread of smog
(Answer)
damage the environment
