I'm taking a test and have to guess the right answer to the question after the article. Article: A super drug that could remove Alzheimer's ,heart disease and diabetes and help people live to 100 is being developed by scientists. Their research is based on the identification of three genes that help prolong lives and prevent diseases which occur in old age. Medically controlling the proteins made by the " longevity genes" will allow millions to live longer, predicts Dr Nir Barzilai. Those whose DNA strongly features the three genes are 80 percent less likely to develop Alzheimer's. The genes also fight against the deadly impact of smoking, poor diet, obesity and lack of exercise. Already, several laboratories are working on a pill to imitate the benefits of the genes and Dr Barzilai thinks it could be tested within three years. The pill could remove some diseases that damage old age. " The advantage of finding a gene that involves longevity is that we can develop a drug that will imitate exactly what this gene is doing," he said. Of the three longevity genes, two genes increase the production of so-called good cholesterol , which reduces the risk of heart disease. The third prevents diabetes. They were discovered by Dr Barzilai's team while studying the DNA of 500 Ashkenazi Jews with an average age of 100. The chances of living that long are one in 10,000 but the group, which shared relatively few common ancestors, was 20 times more likely to hit the entury. Dr Barzilai said: " 30 percent of them were obese or overweight and 30 percent smoked two acks of cigarettes a day for more than 40 years, however they can live to 100." But Andrew Ketteringham of the Alzheimer's Society said: "Alzheimer's disease, a most common disease, is likely to be caused by a combination of genetic disosition , lifestyles and life events. Many genes are probably involved. Question: What is Andrew Ketteringham's attitude toward the study? Options: A: Positive B: Negative C: Critical D: Cautious

I'm taking a test and have to guess the right answer to the question after the article. Article: Do women's minds work the same as men's? Absolutely not. At least, that is what most men are convinced of. Psychologists view the subject either as a matter or frustration or a joke. Now the biologists have moved into this minefield, and some of them have found that there are real differences between the brains of men and women. But being different, they point out hurriedly, is not the same as being better or worse. There is, however, a definite structural variation between the male and female brain. The difference is in a part of the brain that is used in the most complex intellectual processes-the link between the two halves of the brain. The two halves are linked by a trunkline of between 200 and 300 million nerves, the corpus callosum. Scientists have found quite recently that the corpus callosum in women is always larger and probably richer in nerve fibres than it is in men. This is the first time that a structural difference has been found between the brains of women and men and it must have some significance. The question is "What?", and, if this difference exists, are there others? Research shows that present-day women think differently and behave differently from men. Are some of these differences biological and inborn, a result of evolution? We tend to think that is the influence of society that produces these differences. But could we be wrong? Research showed that these two halves of the brain had different functions, and that the corpus callosum enabled them to work together. For most people, the left half is used for word handing, analytical and logical activities; the right half works on pictures, patterns and forms. We need both halves working together. And the better the connections, the more harmoniously the two halves work. And, according to research findings, women have the better connections. But it isn't all that easy to explain the actual differences between skills of men and women on this basis. In schools throughout the world girls tend to be better than boys at "language subjects"... Question: The corpus callosum functions in _ . Options: A: forming the nerve fibers. B: differing man from woman. C: enabling the brain to work. D: processing the most complex intellectuality.

I'm taking a test and have to guess the right answer to the question after the article. Article: If you are not comfortable with school learning, there is another option for you--cyberschool. Cyberschool can also provide a comprehensive teaching service that offers academic guidance and assistance. This is in order to promote the learning process and create a formal, wellstructured environment for learning to take place. The center for Education Reform says the United States has 67 public "cyberschools" and that is about twice as many as two years ago. The money for students to attend a cyberschool comes from the governments of the states where they live. Some educators say cyberschools receive money that should support traditional public schools. They also say it is difficult to know if students are learning well. Other educators praise this new form of education for letting students work at their own speed. These people say cyberschools help students who were unhappy or unsuccessful in traditional schools. They say learning at home by computer ends long bus rides for children who live far from school. Whatever the judgment of cyberschools, they are getting more and more popular. Children get free equipment for their online education. This includes a computer, a printer, books and technical services. Parents and students talk with teachers by telephone or by sending emails through their computers when necessary. Even though cyberschools are therefore not technically a school, mostly they offer a fully complete and comprehensive program that covers a full school day to children up to Grade 9, after which schooling is no longer mandatory . Question: What are educators' opinions about cyberschools? Options: A: They will take the place of traditional schools in the future. B: They waste a lot of money and will do damage to the students. C: They are the solution to the students who do not like to go to school. D: They have brought great convenience to the students.

I'm taking a test and have to guess the right answer to the question after the article. Article: Data on British buying habits in 2015 reveals a move away from products such as sausages and bacon in favour of fish and poultry . The move may be because high-end consumers are noticing growing warnings about their impact on health. That was reinforced by an assessment by the World Health Organization in October that placed cured and processed meats in the same category as asbestos, alcohol, arsenic and tobacco as major causes of cancer. Sales of sausages and bacon were down 14.4% last year compared with 2014 and sales of red meat fell by 8.1%. In contrast, sales of poultry and fish rose by 13.1% and 25.1% respectively. The sustained interest in organic food is driven by an increase in young and socially conscious"millennials"(born from the early 1980s to the early 2000s) with strong social, ethical and environmental values. They are prepared to pay extra for healthier options and shifting shopping patterns away from"the big weekly shop"in favour of"a few and often". At Tesco sales of organic fruit and vegetables have risen by more than 18% over the last year -- double the market average. Tesco fruit commercial manager Gareth Wilcock said,"The revival of organic foods has been gathering pace over the last few years, with lower prices and better availability both playing a major part in that." George Scott, food and grocery analyst with Verdict Retail, said,"Organic food is no longer niche and I think this upward sales trend is here to stay. It is very significant that we have acute consumers who are prepared to trade up to the foods where they want the best quality and assurances of provenance." Question: What can we know about"millennials"? Options: A: They like buying in large quantities. B: They're health-conscious. C: They used to buy a few things. D: They share the same eating habits.
