Article: People with mentally taxing jobs, including lawyers and graphic designers, may end up having better memory in old age, research suggests. A study of more than 1,000 Scottish 70-year-olds found that those who had had complex jobs scored better on memory and thinking tests. One theory is that a more stimulating environment helps build up a "cognitive reserve" to help buffer the brain against age-related decline. The research was reported in Neurology. The team, from Heriot-Watt University, in Edinburgh, is now planning more work to look at how lifestyle and work interact to affect memory loss. Those taking part in the study took tests designed to assess memory, processing speed and general thinking ability, as well as filling in a questionnaire about their working life. The analysis showed that those whose jobs had required complex skills in dealing with data or people, such as management and teaching, had better scores on memory and thinking tests than those who had done less mentally intense jobs such as factory workers, bookbinders, or carpet layers. While the study did not look at biological reasons for the protective effect of certain jobs, potential explanations include that structural changes within the brain mean less damage is accumulated over time. Study leader Dr Alan Gow said: "Our findings have helped to identify the kinds of job demands that preserve memory and thinking later on." "However," He added, "while it is true that people who have higher cognitive abilities are more likely to get more complex jobs, there still seems to be a small advantage gained from these complex jobs for later thinking skills." Dr Simon Ridley, head of research at Alzheimer's Research UK, said the study added to the growing evidence about factors that affected brain health as we aged. "Keeping the brain active throughout life could be helpful and different types of work may play a role. However, it's important to note that this study points to a small and subtle association between occupation and later-life cognition... Question: According to the research, who may have the best memory in old age? - Taxi drivers. - Computer programmers. - Supermarket cashiers. - Motor mechanics.

Read the following article and select the best answer. Article: Don't you find that it is getting increasingly darker every day when you wake up for school ? As winter comes ,days become shorter while the nights become longer ,In the past people slept more in winter ,but in modern times we just use more electric light instead of sunlight to continue our normal routines . But scientific research is finding that manhandling of electric light is making us sick . Electric light is fooling the body's biological clock into releasing awaking hormones ( )at the wrong times ,scientists say .This might be leading to seasonal fatigue and depression . Much more than mental health is at stake ,Recent scientific studies have found that women who work at night ,have higher chances of getting breast-cancer . "Electric lights are wonderful ,but as with a lot of other things ,we really mess ,things up "said David Avery ,a psychiatrist ." Our ancestors evolved in a very regular light -dark cycle ,and our bodies just work better that way ." Researchers have known for a long time that all living things have a biological clock that is linked to light ,Being of the natural day-night cycle can cause fatigue ,mood change and depression ,This is known as seasonal affective disorder ,or SAD. Scientists disagree on the cause of SAD ,Some say it is caused by winter's late sunrises , others blame the early sunsets . However ,they all agree the perfect solution to SAD is to give up artificial light ,It will quickly bring someone into a cycle of long ,restful nights and easy awakenings at dawn . But realistically most people need to use electric light in their everyday life . Ironically the next best solution is to use more bright lights to reset the body's biological clock . By getting bright light first thing in the morning it simulates an earlier dawn and shifts the body clock forward ,according to Alfred Lewy ,a psychiatrist at Oregon Health & Science University . A 2005 study done by the American Psychiatric Association showed that daily exposure to bright light was about as effective as... Question: What is the best solution to treat people with SAD? - Using bright lights to reset the body's clock - Getting bright light in the morning to shift the body clock forward - Daily exposure to bright light . - Giving up artificial light
(Answer)
Using bright lights to reset the body's clock

Read the following article and select the best answer. Article: When it came to role models, Diana Ortiz said her mother, Marcia Dominguez, was the "hero". Ms. Dominguez came to the United States from Cuba in 1979. She went to college and got a job as a social worker --- all the while raising three children in America mostly on her own. "It was always school first," Diana said, "My mom had us in a straight line. If we got out of line, she corrected us. She was a perfect woman. She was beautiful, she had the education and she had everything --- but the illness took over. When I was 11, it frightened me to see how quickly my mother's health was ruined by cancer. A week before I turned 14, my mother died at age 50. I had tried to prepare myself, but on the first morning I woke up without my mother, the sense of loss was painful." Diana had not seen her father for five years, who refused to provide for her. Diana then entered the city's foster care system. She has spent about four years in foster homes. Despite Diana's hard teenage years, the values her mother had planted in her mind inspired her to go after higher education. Since August 2010, she has been a fulltime student majoring in law. A public organization offers her tuition but she has part-time jobs to help people like her and earn more life experience. Her goal is a job in the Federal Bureau of Investigation. For now, Diana works 20 hours a week as a cashier at Marshalls, earning $7.25 an hour. In November, she moved into her own public housing studio apartment on the Lower East Side. She pays $236 a month in rent. Although she is out of foster care, Diana has been speaking at workshops for foster youths. She emphasizes that nothing should get in the way of their success, not the trials of their lives or what they may have lost. "I tell the young who have the similar experience like me, 'Why are you going to let what happened to you affect you in the long run?' " Diana said. " 'Why are you going to sit there and feel sorry for yourself? You're wasting precious time.' It is a message my mother would approve of. My... Question: What did Ms. Dominguez find most important for her children? - Staying in a straight line for coherence. - Making punctual self-correction. - Struggling to run after perfection. - Receiving excellent education.
Receiving excellent education.
