Read the following article and select the best answer. Article: The Crowne Plaza Hotel in Copenhagen is offering a free meal to any guest who is able to produce electricity for the hotel on an exercise bike linked to a generator ,The idea is to get people fit and reduce their carbon footprint. Guests will have to produce at least 10 watt hours of electricity -- roughly 15 minutes of cycling for someone of average fitness. Guests staying at Plaza Hotel will be given meat tickets worth $36 once they have produced 10 watt hours of electricity. The bicycles will have smart phones attached to the handlebars measuring how much power is being generated for the hotel. The plan, a world-first, will start on 19 April and run for a year. Only guests staying at the hotel will be able to take part. Frederikke Toemmergaard, hotel spokeswoman, said, "Many of our visitors are business people who enjoy going to the gym. There might be people who will cycle just to get a free meal, but generally I don't think people will take advantage of our programme," Copenhagen has a long-standing cycling tradition and 36% of locals cycle to work each day, one of the highest percentages in the world, according to the website visitcopenhagen.dk. US environmental website treehugger.com recently voted Copenhagen the world's best city for cyclists. "Because Copenhagen is strongly connected with cycling, we felt the bicycle would work well as a symbol of the hotel's green profile ." If successful, the electric bicycle meal programme will be spread to all Crowne Plaza hotels in the UK, the hotel said in a statement. Question: How can a participant get a free meal? - By becoming a professional cyclist. - By cycling to produce some electricity. - By linking a smart phone to a bicycle. - By monitoring his or her carbon footprint.
By cycling to produce some electricity.

(Question)
Read the following article and select the best answer. Article: As a society we might want to rethink the time and money spent on education,so that these resources can benefit a greater percentage of the population.Ideally,both high schools and colleges can prepare individuals for the ever-changing roles. High school degrees offer far less in the way of preparation for work than they might,or than many other nations currently offer,creating a growing skills gap in our economy.We encourage students to go on to college whether they are prepared or not,or have a clear sense of purpose or interest,and now have the highest college dropout rate in the world. We might look to other countries for models of how high schools can offer better training,as well as the development of a work ethic and the intellectual skills needed for continued learning and development. Meanwhile,the liberal arts become more important than ever.In a knowledge economy where professional roles change rapidly and many college students are preparing for positions that may not even exist yet,the skillneeded is one that prepares them for change and continued learning. Learning to express ideas well in both writing and speech,knowing how to find information,and knowing how to do research are all solid background skills for a wide variety of roles,and such training is more important than any particular major in a liberal arts college.We need to continue to value broad preparation in thinking skills that will serve for a lifetime. Students also need to learn to work independently and to make responsible decisions.The lengthening path to adulthood appears exacerbated by parental involvement in the college years.Given the rising investment in college education,parental concern is not surprising,but learning where and when to intervene willhelp students take more ownership of the outcomes of these increasingly costly educations. Question: What kind of education does the author think is ideal? - It benefits the great majority of the general population. - It prepares students to meet the future needs of society. - It encourages students to learn throughout their lives. - It ensures that students'expectations are successfully fulfilled.
(Answer)
It prepares students to meet the future needs of society.

Ques:Read the following article and select the best answer. Article: Researchers at Sweden's KTH Royal Institute of Technology say they have found further proof that the wolf ancestors of today's dogs can be from southern East Asia -- findings that are contrary to theories placing the birth place in the Middle East. Dr Peter Savolainen, KTH researcher in evolutionary genetics, says a new study released Nov. 23 confirms that an Asian region south of the Yangtze River was the principal and probably the only region where wolves were domesticated by humans. Research data show clearly that dogs are descended from wolves, but there's never been scientific agreement on where in the world the domestication process began. "Our analysis of Y-chromosomal DNA now confirms that wolves were first domesticated in Asia south of Yangtze River -- we call it the ASY region -- in southern China or Southeast Asia," Savolainen says. The Y data supports previous evidence from mitochondrial DNA. "Taken together, the two studies provide very strong evidence that dogs appeared first in the ASY region," Savolainen says. Archaeological data and a genetic study recently published in Nature suggest that dogs originate from the Middle East. But Savolainen rejects that view. "Because none of these studies included samples from the ASY region, evidence from ASY has been overlooked," he says. Peter Savolainen and PhD student Mattias Oskarsson worked with Chinese colleagues to analyse DNA from male dogs around the world. Their study was published in the scientific journal Heredity. Approximately half of the gene pool was universally shared everywhere in the world, while only the ASY region had the entire range of genetic diversity. "This shows that gene pools in all other regions of the world most probably originate from the ASY region," Savolainen says. "Our results confirm that Asia south of the Yangtze River was the most important -- and probably the only -- region for wolf domestication, and that a large number of wolves were domesticated," says Savolainen. In separate research published recently in Ecology... Question: What is special about mitochondrial DNA? - It is only used in studying evolutionary relationships. - It alone can provide hard evidence for Savolainen's research. - It is the most useful in finding out the birth place of dogs. - It comes from the mother of most animals and plants.

Ans:
It comes from the mother of most animals and plants.
