Q: Write a multi-choice question for the following article, with the given choices and answer: Article: What's the greenest place in America? If you answered something like the warm sunlight of Santa Barbara, you'd be wrong. The greenest place in America has almost no sign of nature-- the buildings outnumber the trees-- and the air isn't all that great. What it has is density and efficiency-- the twin qualities that finally define green in the global warming time. Applying those standards,the greenest place in America is New York City-- particularly,the overcrowded,overpriced island of Manhattan, which produces 30% less per-capita greenhouse gas than that of the nation. It's that density that makes Manhattan so green. Manhattan's population density is 800 times the national average. Density comes with negatives,certainly-- small living spaces,air pollution-- but it also enables amazing efficiencies.Over 80% of Manhattanites travel to work by public transport, by bike or on foot-- compared to an average of about 8% everywhere else in the country. Manhattan's apartment buildings are far more energy-efficient than the houses in the suburbs. What's true of New York City is more or less true of other American urban areas, which explains why a growing part of the environmental movement now focuses on greening cities, hoping to attract more Americans back downtown. There's an effort to make cities more sustainable ,by improving public transport,reducing air pollution and upgrading energy efficiency. But even more important, it is quite urgent to change decades of government policies that have been in favor of the suburbs,with disastrous consequences for energy,the environment and the climate. That's exactly the difficult point. For all the high efficiency and convenience and richness of living in a city,there are disadvantages too.New York,for example,has some of the highest childhood asthma rates in the U.S. So it's welcome news that New York has continued to push its P1aNYC scheme, a long-term program to make the city greener and more sustainable over the next decades. Recently _ announced an update to the plan that... Options: A buildings and trees B density and efficiency C sunlight and nature D transport and population Answer: B density and efficiency Question:
A: Manhattan is considered as the greenest place in America because of its _

Question: Write a multi-choice question for the following article, with the given choices and answer: Article: Spending hours playing violent video games prevents teenagers from their moral growth, a study has found.It is thought that regular touch to violence and lack of contact with the outside world makes it harder for them to tell right from wrong.They also struggle to trust other people,and see the world from their viewpoints. Researchers from Brock University in Ontario found that those who spend more than three hours each day in front of the screen are particularly unlikely to have developed the ability to empathise . The Canadian researchers surveyed 109 boys and girls,aged 13 and 14,about whether they played video games,which games they liked,and how long they spent playing them.Their findings found that 88 percent of teens said they played games,and more than half admitted to playing games everyday.Violent games were among the most popular. The teenagers also filled in a questionnaire designed to measure their moral development.For example,they were asked how important it is to save the life of a friend. Previous studies have suggested that a person's moral judgement goes through four phases as they grow from children and enter adulthood.By the age of 13 or 14,scientists claim young people should be entering the third stage,and be able to empathise with others and take their viewpoints into account.The research found that this stage appeared to be delayed in teenagers who regularly played violent video games. It is also thought that teenagers who play games regularly did not spend enough time in the real world to learn to take other's thoughts into consideration.Researcher Mirjana Bajovic said:"The present results indicate that some teenagers;who spent three or more hours a day playing violent video games,are deprived of such opportnnities."Writing in the journal Educational Media International.the researchers added:"Touch to violence in video games may influence the development of moral reasoning because violence is not only presented as acceptable but is also justified and rewarded." ... Options: A Parents and teachers should let teens go online. B Playing video games should be forbidden among teens. C Game designers should be kindly treated and rewarded. D Teens should be encouraged to do more meaningful things. Answer: D Teens should be encouraged to do more meaningful things. Question:

Question: Write a multi-choice question for the following article, with the given choices and answer: Article: Sure,you've watched extreme pet sports on Animal Planet. But did you know that there's a whole world of athletic activities for dogs right in our area? There are some reasons for considering taking part in such activities. Such sports strengthen the close feelings between dog and owner,and also benefit your pup's body and mind." Dogs that are tied with chains often have behavioral problems," says Lee Morgan. "They love to go out and play as much as we do." Of course,many of these sports require some amount of practice,and some breeds are simply better at certain activities than others .But all dogs can participate in the following games. Frisbee Dogs This sport requires you to throw as many Frisbees as your dog can catch in a 60second time period. The further out your dog catches the Frisbee,the more points you rack up. Extra points are awarded if your pet catches the Frisbee while it's still in the air. Mid Atlantic Disc Dogs (MADDogs) hosts local competitions and offers informal instruction in local parks or even in people's backyards. Flyball Dogs The sport has been around since 1970s.Flyball is a relay race with four dogs in a team. Each must jump four hurdles spaced with 10 feet apart and then land on a springloaded box that shoots out a tennis ball. The dog must then catch the ball and run back over the four hurdles. Once that's done,the next dog can go. The first team that successfully completes the course wins the competition. There are a number of local teams,including 4 Dog Night,which holds classes for beginners and intermediate players and is always looking for new team members. The Beltway Bandits is another team,based in Leesburg,that hosts private classes and competitions.
