[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: Think about what you usually have for a meal: Is it a hamburger? What about vegetables? Would it surprise you to learn that what you eat can affect the whole planet? It can--in a big way. Scientists attending the American Association for the Advancement of Science meeting in Chicago presented new studies showing how food and its production affect the globe and its warming climate. It is generally believed that global warming is caused by the large amounts of greenhouse gases released into the atmosphere. One of these greenhouse gases is carbon dioxide. What does this have to do with food? A big part of the carbon dioxide comes from the process of making and eating food, the scientists reported in Chicago. The production of meat contributes to a lot of that carbon dioxide. The process of making a hamburger, for example, requires a lot of energy. A cow has to be fed and raised on farmland, and cow manure is a major source of methane --an especially powerful greenhouse gas. By the time a hamburger is finally served on a dinner plate, it has done great harm to the environment. The message from the research is clear: We can greatly reduce the production of greenhouse gases by eating less meat. All kinds of meat, the scientists reported, are harder on the planet than vegetables. To grow and eat a pound of potatoes, for example, sends less than one-quarter pound of carbon dioxide or other greenhouse gases into the air. So shifting our diet to less meat and more vegetables ,as it turns out, may do the world some good. Options: A cutting down too many trees. B releasing too many greenhouse gases. C growing too many vegetables. D raising too many cows. Answer: B releasing too many greenhouse gases. Question:

[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: After a 15-year ban on the sale of fireworks in Beijing, Kang Guoliang, 51, was able to start his old trade again yesterday. As a salesman in Xinhui store in Dongcheng District, he is happy about the increasing number of buying fireworks wrapped in red paper -- a color standing for happiness and good luck. "Fireworks are available for the first time in town for more than a decade," Kang said happily."People will buy them." The store has 300 boxes of fireworks piled up and is open 24 hours at the moment.Residents are buying the fireworks and firecrackers for the upcoming Spring Festival, which falls on February 18. Citywide, 2,116 registered stores and retailers, 585 in the centre and 1,600 on the outskirts are trading fireworks in the Chinese capital.Sales of fireworks within the Fifth Ring Road started yesterday and will last until March 4, Xinhua reported.Among the stores, 117 stores are permitted to operate 24 hours.About 600,000 boxes of firecrackers worth more than 100 million yuan have been carried to registered stores. The Chinese capital began a ban in 1993 to reduce fireworks-related deaths and fires during the holiday season.Last September the ban was removed in response to residents' fondness for fireworks when celebrating Spring Festival. According to new rules, Beijing residents are allowed to set off fireworks within the Fifth Ring Road all day on Lunar New Year's Eve and Lunar New Year's day, from 7 a.m.to midnight every day from February 19 to March 4. "Spring Festival without fireworks is not Spring Festival," said Sheng Hefei, who was buying fireworks in the store."It was fun to light the firecrackers when I was little," he said."The sound and view of fireworks make a real holiday." However, not all residents welcome the return of firecrackers because of injuries, pollution and noise."My child is scared of the sudden sound of firecrackers, and it is annoying to hear it all night long," complained Lu Jun, a local resident.

[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: The Namib Desert in Africa is one of the driest places on earth.With half an inch of rain falling every year,humans call barely survive there for a week with no water.But the Namib beetle does just fine.It collects morning dew that condenses on its back. Inspired by this little creature,27--year--old Edward Linacre,a former student from Swinburne University of Technology in Melbourne,Australia,has designed a new"Airdrop" irrigation system which can pull water from even the driest desert air.His invention won the 2011 James Dyson Award,an international design award.Hopes are high that the system will be able to solve the problems of growing plants on dry land,according to the may Mail. Linacre studied the Namib beetle and found that it had hydrophilic skin on its back,which helped catch water molecules passing in the air.These water molecules accumulated into small drops of liquid water.He realized that as long as the air temperature was low enough,even the driest air contains water molecules that can be extracted . Following this principle,he designed the new system which works by pumping air through a network of underground pipes to cool it to the point at which water condenses.The water is then delivered directly to the roots of plants. According to the research,about 11.5 milliliters of water could be collected from every cubic meter of air in the driest desert.Further development could raise that number even higher . The idea of getting water from the air is not new.However,the Airdrop has certain advantages compared with its competitors.Similar systems often require great amounts of energy because they use refrigeration equipment to lower the temperature.But Airdrop simply uses the temperature difference between the air and the cool earth underground Options: A can collect morning dew in the air B is designed to help the Namib beetle C works by pumping water through pipes D cools air to the point at which water condenses Answer: D cools air to the point at which water condenses Question:
