Read the following article and select the best answer. Article: Everyone wants to know the secrets of a long and healthy life. Here are some discoveries from health experts. Many studies looking into the lives of centenarians look at what they eat. Many people who live into their hundreds live in the Mediterranean , so their diet, which is high in fruits, vegetables, nuts, and healthy fats like olive oil, gets a lot of attention. The diet has been linked to a healthier older age, lower risk for heart disease, and even protection against memory loss. Education is related to a longer life. A 2012 report from the CDC's National Center for Health Statistics found that people with a bachelor's degree or higher live about nine years longer than people who don't graduate high school. James Smith, a health economist at the RAND Corporation, is also a supporter of the argument for staying in school for better life expectancy. His findings show education should be an even bigger factor than race and income. Educated people are more likely to land better jobs, plan for their future, and make healthier lifestyle choices. Being a hard worker doesn't necessarily mean job-stress will harm you. The Longevity Study found that plenty of hard workers lived long lives. "Skeptics may wonder if hard workers really are enjoying life." the authors write, "We found that productive, hardworking people (even in old age) are not stressed or miserable, but tend to be happier, healthier, and more socially connected than their less productive peers." Having a strong social group is associated with a longer life. We often turn to friends and family for support, and taking care of the people that matter to us may help us take better care of ourselves, some evidence shows. Some research even suggests that immune function is improved when we are around our friends, and that they help with stress management. Research shows that sitting for long period of time put people at risk for shorter lifespans and other health risks. A 2011 study found that each hour people spent sitting down and watching TV after...

(Question)
Read the following article and select the best answer. Article: On April 24th, another natural disaster-the oil spill in the Gulf of Mexico, happened. Millions of dollars have been used to help stop the spill and to clean up the animals, beaches, and land spoiled by the oil. Unfortunately, when many of these chemicals are used, more damage is caused to the environment, especially to lives in the sea. But governments seem to accept the _ of transporting mil-lions of tons of oil by ship every day so that we can fill up our cars and drive around and cause even more environmental damage. Interestingly, the biggest companies in the world produce cars, and the next biggest supply the gasoline to make them run. Of all of today's environmental disasters, an oil spill may actually be one of the least serious. Although oil is poisonous, it is a natural material. In the end, it breaks down naturally. In 1967 the tanker Torrey Canyon sank off the Scilly Isles near the coast of England and spilled 120,000 tons of oil into the ocean. If you go there today, you will find it hard to see any sign that it ever happened. However, we should be thinking more about reducing our dependency on oil. Governments should be encouraging research into new technologies, such as cars run by solar power, electricity, hydro-gen, and so on. Much of this research, in the past, was stopped by the oil, gas, and coal. If the world's millions of cars were 10% more efficient ,we would need many fewer tankers crossing the oceans each year. If this happened, the risks of oil spills would be reduced, and the air we breathe would be cleaner and fresher, too. Question: What is the passage mainly talking about? - Oil spills pollution. - What oil pollution is. - Oil tanker accidents. - How to reduce oil pollution.
(Answer)
Oil spills pollution.
