PROBLEM: Article: New research at Washington University School of Medicine in St. Louis shows that people who struggle with mood problems or addiction can safely quit smoking and that kicking the habit is associated with improved mental health. Cavazos-Rehg, an assistant professor of psychiatry, found that quitting or significantly cutting back on cigarette smoking was linked to improved mental health outcomes. Quitting altogether or reducing by half the number of cigarettes smoked daily was associated with lower risk for mood disorders like depression, as well as a lower likelihood of alcohol and drug problems. "We don't know if their mental health improves first and then they are more motivated to quit smoking or if quitting smoking leads to an improvement in mental health," Cavazos-Rehg said. "But either way, our findings show a strong link between quitting and a better psychiatric outlook." In addition, she believes the serious health risks associated with smoking make it important for doctors to work with their patients to quit, regardless of other psychiatric problems. "About half of all smokers die from related to smoking, so we need to remember that as complicated as it can be to treat mental health issues, smoking cigarettes also causes very serious illnesses that can lead to death," she explained. Cavazos-Rehg and her team analyzed questionnaires gathered as part of the National Epidemiologic Study on Alcohol and Related Conditions. In the early 2000s, just under 35,000 people were surveyed. As part of the study, they answered questions about drinking, smoking and mental health in two interviews conducted three years apart. The researchers focused on data from 4,800 daily smokers. Those who had addiction or other psychiatric problems at the time of the first survey were less likely to have those same problems three years later if they had quit smoking. And those who hadn't had psychiatric problems at the initial survey were less likely to develop those problems later if they already had quit. "We really need to spread the word and encourage doctors and patients to tackle these problems," Cavazos-Rehg said. "When a patient is ready to focus on other mental health issues, it may be an ideal time to address smoking cessation, too."

PROBLEM: Article: The round-the-clock availability that cell phones have brought to people's lives may be _ amily life, a new study suggests. The study, which followed more than 1300 adults over 2 years, found that those who consistently used a mobile phone through out the study period were more likely to report negative "spillover" between work and home life--and, in turn, less satisfaction with their family life. Spillover(,) actually means that the line between work and home began to become unclear. Work life may invade home life--when a parent is taking job-related calls at home, for instance--or family issues may start to take up work time. For example, a child may call Mom at work, telling her "the microwave exploded", explained Noelle Chesley, an assistant professor of society at the University of Wisconsin Milwaukee and the author of the study. The problem with cell phones seems to be they are allowing for ever more spillover between work and home. This may be especially true for working women, the study found. Among men, consistent use of mobile phones seemed not to allow more work issues to creep into family time. But for women, the spillover tended to go in both directions--being "connected" means that work cuts into home time, and family issues come into work life. Cell phones seem to be opening more lines for stressful exchange among family members. But there may be ways to control the spillover, according to Chesley. Employers, she said, should look at their policies on contacting employees after working hours to make sure their expectations are "reasonable". For their part, employees can decide that cell phones go off during family time, Chesley said.
Question: What is the main idea of this passage?
Options: (A) Cell phones offer 24-hour availability. (B) Cell phones get life and work mixed. (C) Women don't use cell phones in an effective way. (D) Men are better at dealing with family problems.

PROBLEM: Article: Every year, billions of kilograms of fresh produce are wasted in the United States. Meanwhile, millions of poor Americans go hungry, without access to healthy and affordable meals. Evan Lutz, CEO and founder of Hungry Harvest, was inspired to act after seeing extreme poverty in areas of Baltimore. Maryland. He wants to reduce the so-called food desert in that area. His work is to make sure to food goes to waste and no person is ever hungry in America. And he combines that goal with a love for business. Hungry Harvest is a business which collects and sells fruits and vegetables that most food companies will throw away. Everything doesn't grow the same way on a farm. But all that is too big or too small gets thrown out. That is why everything in a grocery store looks similar. Hungry Harvest will box those imperfect ones and deliver them to customers once a week. For every purchase, Hungry Harvest delivers healthy food to people in need. Hungry Harvest has recovered 300,000 pounds of produce to date and provided 100,000 pounds to those in need. Lutz established Hungry Harvest in 2014. Its success depends on team work. Every week on Monday or Tuesday they will decide what will go into the next week's box by calling up packing houses and wholesalers to see what they will normally throw away that week. They then place the order. The last step is to send goods to customers. In January 2016, Lutz appeared on the American business competition television show "Shark Tank" and got even more than he expected: $100,000. Lutz is using the money to expand. Actually, more than six billion pounds are wasted each year due to "ugly" surface. Hungry Harvest is on the way to saving more food from going to waste and feeding hungry families.
