Question: Ques: Read the following article and select the best answer. Article: "Enough" with the multivitamins already. That's the message from experts behind three new studies that tackled an often debated question: Do daily multivitaminsmake you healthier? "We believe that the case is closed - supplementing  the diet of well-nourished adults with (most) mineral or vitamin supplements has no clear benefit and might even be harmful," concluded the authors of the editorial summarizing the new research papers. They urge consumers to not 'waste' their money on multivitamins. "The 'stop wasting your money' means that perhaps you're spending money on things that won't protect you long term," editorial co-author, Dr. Edgar Miller said, "What will protect you is if you spend the money on fruits, vegetables, nuts, beans, low fat dairy, and things like that. Exercising would probably be a better use of the money." The strong message was based on a review of the findings from three studies that tracked multivitamins link to cancer protection, heart health, and brain and cognitive  measures. The first study looked at vitamin supplementation's role in preventing chronic  disease. The next study looked at whether long-term use of multivitamins would have any effect on slowing cognitive decline. The third study looked specifically at multivitamins and minerals role in preventing heart attack. "The three studies found no difference in rates of chronic disease, heart attack and the need for hospitalization between vitamin-takers and placebo -takers." Dr. Edgar Miller stated. One expert agreed some nutrient-deficient people may still benefit from multivitamins. "There might be an argument to continue taking a multi(vitamin) to replace or supplement your not healthy diet," Dr. Edgar Miller added. He also notes that vitamins can benefit people with celiac disease and those who are pregnant. Question: What can be inferred from the text? - Vitamin supplements have proved harmful to the health of adults. - Vitamin supplements are beneficial in certain conditions. - Nowadays taking vitamin supplements is common to most people. - Daily multivitamins will make you healthier.
Ans: Vitamin supplements are beneficial in certain conditions.

Ques: Read the following article and select the best answer. Article: BC Social Report, August 14, 2010 Scandinavians may spend a lot of the winter in darkness but they are the happiest people in Europe, according to a study showed this month. Countries like Denmark and Finland scored highest on the study of happiness in Europe carried out by Cambridge University, which also found that the sunny southern countries of Italy, Portugal and Greece got the least joy out of  life. The survey entitled:  "No Man is an Island" showed that countries where people enjoy time with friends and family, have trust in government and national institutions were more likely to be happy than those living in a sunny climate. The study rated respondent on their overall sense of happiness and life satisfaction on a _ of one to 10. Danes  --who expressed a high level of trust in their politicians and public institutions--came top of the field at 8.3. Italians--who reported lower levels of satisfaction with their national quality of government--came last at 6.49.' "Italy, Greece, Portugal, Germany and France report the lowest levels of happiness while the Scandinavian Countries, Netherlands and Luxembourg report the highest," the study said. Although Europeans are generally four times wealthier than their fathers and grandfathers, their levels of happiness are either equal to or lower than 40 years ago. The study also looked at factors contributing to happiness within countries and surprisingly found that an interest in politics actually increased happiness. Lead researcher Luisa Corrado said tax cuts and throwing money at social problems appeared to have no effect on the happiness of citizens when compared with government policies which strengthened and supported wider social networks.  "People are less naive ( ) than one would expect, politicians need to adapted their policies and target specific problems in specific areas," she said. Question: According to the passage, we can know  _ - Scandinavians are the happiest people in the world - the research is carried out by Oxford University - the people of the northern countries are much happier - Italians expressed their trust in politics and institutions
Ans: the people of the northern countries are much happier

Ques: Read the following article and select the best answer. Article: Their cheery song brightens many a winter's day. But robins are in danger of wearing themselves out by singing too much. Robins are singing all nightas well as during the day, British-based researchers say. David Dominoni, of Glasgow University, said that light from street lamps, takeaway signs and homes is affecting the birds' biological clock, leading to them being wide awake when they should be asleep. Dr Dominoni, who is putting cameras inside nesting boxes to track sleeping patterns, said lack of sleep could put the birds' health at risk. His study shows that when robins are exposed to light at night in the lab, it leads to some genes being active at the wrong time of day. And the more birds are exposed to light, the more active they are at night. He told people at a conference, "There have been a couple of studies suggesting they are increasing their song output at night and during the day they are still singing. Singing is a costly behaviour and it takes energy. So by increasing their song output, there might be some costs of energy." And it is not just robins that are being kept awake by artificial light. Blackoiids and seagulls are also being more nocturnal. Dr Dominoni said, "In Glasgow where I live, gulls are a serious problem. I have people coming to me saying `You are the bird expert. Can you help us kill these gulls?'.During the breeding season, between April and June, they are very active at night and very noisy and people can't sleep." Although Dr Dominoni has only studied light pollution, other research concluded that robins living in noisy cities have started to sing at night to make themselves heard over loud noise. However, some birds thrive in noisy environments. A study from California Polytechnic University found more hummingbirds in areas with heavy industrial machinery. It is thought that they are capitalising on their predators fleeing to quieter areas. Question: Why do some birds thrive in noisy environments? - Because there are fewer dangers. - Because there is more food to eat. - Because there is less light pollution - Because there are more places to take shelter.
Ans:
Answer: Because there are fewer dangers.
