Question: Read the following article and select the best answer. Article: While other countries debate whether to fix wind turbines offshore or in distant areas, Denmark is building them right in its capital. Three windmills were recently introduced in a Copenhagen neighbourhood, and the city plans to add another 97. "We've made a very ambitious commitment to make Copenhagen CO2-neutral by 2025," Frank Jensen, the mayor, says. "But going green isn't only a good thing. It's a must." The city's carbon-neutral plan, passed two years ago, will make Copenhagen the world's first zero-carbon capital. With wind power making up 33% of Denmark's energy supply, the country already features plenty of wind turbines. Indeed, among the first sights greeting airborne visitors during the landing at Copenhagen's Kastrup airport is a chain of sea-based wind towers. By 2020, the windswept country plans to get 50% of its energy from wind power. Now turbines are moving into the city and these ones will cost less than half the price of those sea-based. Having the energy production closer makes it cheaper, and land-based turbines are the cheapest possible source of energy available today. Fixing them also makes the locals more aware of their energy consumption. Though considerably less attractive than it was in ancient times, the windmill is enjoying popularity in the 21st century. "Windmills are a symbol of the new and clean Copenhagen," says resident Susanne Sayers. Meanwhile, fellow Copenhagen citizen Maria Andersen worries about the noise, explaining that she wouldn't want a wind turbine in her neighbourhood. While Copenhagen citizens approve of the windmills, they're less willing to live close to one. The answer, the city has decided, is to sell turbine shares. Each share represents 1,000 kW hours/year, with the profit tax-free. With a typical Copenhagen household consuming 3,500 kW hours/year, a family buying four shares effectively owns its own renewable energy supply. To date, 500 residents have bought 2,500 shares. Involving the local population was a smart move. "There are a lot of things you... Question: How has the city of Copenhagen persuaded its people to accept the windmills around their homes? - By promising them that all their income is free of tax. - By designing less noisy windmills to ease their worries. - By convincing them that land-based turbines are much cheaper. - By offering them the chance to get the profit the windmills bring.
Answer: By offering them the chance to get the profit the windmills bring.

Question: Read the following article and select the best answer. Article: The first chocolate was eaten by people in Central and South America hundreds of years ago. In those days, people did not really eat chocolate; the cocoa bean was used to make a chocolate drink that the people enjoyed very much. Much later the cocoa bean was brought to Europe and people there also came to love the taste of it. In 1824, John Cadbury opened a small shop in Birmingham. One of the items he sold was cocoa powder to be made into drinks. In 1831, he opened a small factory to make cocoa powder from cocoa beans. John Cadbury believed that alcohol was an important cause of people's being poor, and he wanted to encourage people to drink chocolate instead. A few years later a man called Joseph Fry invented a way to make chocolate bars, and so for the first time people had the chance to eat chocolate instead of only drinking it. At first, chocolate was luxury and only the rich people could buy it. Later, as more and more chocolate bars were produced and sold, they became cheaper. However, at first, only plain chocolate was produced. Milk chocolate came later and this was made by adding milk or milk powder to the chocolate. Cadbury introduced their first milk chocolate bars in 1897. Their most famous chocolate, Cadbury's Milk Bar, was introduced in 1905. It has been a best-seller in Britain and around the world for nearly 100 years. The Cadbury factory is still in Birmingham and the chocolate produced there is eaten all over the world. Every year, thousands of visitors visit the factory to see how chocolate is made. Question: People started to eat chocolate when _ . - milk was added to chocolate - more milk chocolate was made - chocolate became cheaper - chocolate bars were made
Answer: chocolate bars were made

Question: Read the following article and select the best answer. Article: Passage 1 The Information Highway is the road that links computer users to a large number of on-line services: the Web,e-mail,and software,to mention just a few. Not long ago,the Information Highway was a new road,with not many users. Now,everyone seems to want to take a drive, with over 30 million families connected worldwide. Not surprisingly, this well-traveled highway is starting to look like a well-traveled highway. Traffic jams can cause many serious problems,forcing the system to close down for repair. Naturally,accidents will happen on such a crowded road,and usually victims are some files,gone forever. Then,of course,there' s Mr. Cool,with his new broad-band connection,who speeds down the highway faster than most of us can go. But don' t trick yourself:he pays for that speeding. Passage 2 Want to know more about global warming and how you can help prevent it?Doctor Herman Friedman,who is considered a leading expert on the subject,will speak at Grayson Hall next Friday. Friedman studied environmental science at three well-known universities around the world before becoming a professor in the subject. He has also traveled around the world observing environmental concerns. The gradual bleaching of the Great Barrier Reef,which came into the public eye in 2002,is his latest interest. Signed copies of his color1ful book,which was p ublished just last month,will be on sale after his talk. Question: How does Mr. Cool manage to travel the Information Highway so fast? - By storing fewer files. - By repairing the system. - By buying a better computer. - By using a broad-band connection.
Answer:
By using a broad-band connection.
