Write a multi-choice question for the following article: Article: Older women who regularly drink green tea may have slightly lower risks of stomach and throat cancers than women who don't, according to a Canadian study that followed thousands of Chinese women over a decade. For the study, researchers used data from a long-running health study of over 69,000 middle-aged and older Chinese women. The researchers found that those who drank green tea at least three times a week were 14 percent less likely to develop a cancer of the digestive ( ) system. More than 19,000 were considered regular green-tea drinkers, who drank it more than three times a week. Over 11 years, 1,255 women developed a digestive system cancer, In general, the risks were somewhat lower when a woman drank green tea often and for a long time. Green tea contains certain chemicals which may reduce the body-cell damage that can lead to cancer and other diseases. Women who _ a lot of green tea in the study were also younger, ate more fruits and vegetables, exercised more and had higher-income jobs. None of the women smoked or drank alcohol regularly, and the researchers also collected information on their diets, exercise habits, weight and medical history. Yet even with all these things factored in, women's tea habits remained linked to their cancer risks, they noted, even though this type of study cannot prove cause and effect. The study adds to debate over the effect of green tea on cancer risks, Past studies have so far come to conflicting findings on whether green tea drinkers really do have lower cancer risks.Nobody can say whether green tea itself is the reason, since green tea lovers are often more health-conscious in general.
Ans: Question: The study lasted for more than _ .Options:A three yearsB five yearsC eight yearsD ten yearsAnswer:D

Write a multi-choice question for the following article: Article: It is said that there's no such thing as a free lunch, but even if you manage to bag a bargain meal, it will not taste as good as a more expensive choice, according to scientists. A new study has found that restaurant goers who pay more for their meals think the food is tastier than offered for a smaller price. The experts think that people tend to associate cost with quality and this changes their perception of how food tastes. Scientists at Cornell University studied the eating habits of 139 people enjoying an Italian buffet in a restaurant. The price of the food was set by the researchers at either $4 or $8 for the all-you-can-eat meal. Customers were asked to rate how good the food tasted, the quality of the restaurant and to leave their names. The experiment showed that the people who paid $8 enjoyed their meal 11% more than those who ate the "cheaper" buffet. Interestingly those that paid for the $4 buffet said they felt guiltier about loading up their plates and felt that they overate. However, the scientists said that both groups ate around the same quantity of food in total. Brian Wansink, a professor of consumer behavior at the university, said: "We were fascinated to find that pricing has little effect on how much one eats, but a huge effect on how you interpret the experience." He thinks that people enjoyed their food more as they associated cost with quality and that small changes to a restaurant can change how tasty people find their meals. In a previous study, researchers from the university showed that people who eat in bright lighting consume more than people who eat in less brightly lit areas.
Ans: Question: According to the passage, which of the following factors has an effect on the quantity of food a person consumes?Options:A The taste of the food.B The price of the food.C The number of companions.D The lighting of the restaurant.Answer:D

Write a multi-choice question for the following article: Article: (1) Liu Xiang got another gold medal in the 110m hurdles at the East Asian Games (EAG) in Macao last Wednesday. The 22-year-old Liu defended his EAG title in 13.21 seconds, beating Shi Dongpeng (13.36) and Japan's Kota Kumamoto (13.89). His winning time was 0.16 seconds behind his top time this year and a further 0.08 behind this season's best: 12.97 set by Frenchman Ladji Doucoure, who beat Liu into second place in the world championships. (2) Over 30,000 people were killed in the huge earthquake that took place in India, Pakistan and Afghanistan on October 8. Millions were left homeless after the quake destroyed houses, cutting off power and water. The international community has responded to the countries' call for help. China has sent a rescue team, along with money and relief materials . But because of bad weather, it is difficult for them to reach those in remote areas. The United Nations warned of a possible outbreak of infectious diseases .

Write a multi-choice question for the following article: Article: Scientists have found what look like caves on Mars , and say they could be protecting life from the planet's terrible environment. The first caves discovered beyond the Earth appear as seven mysterious black dots on the pictures sent back by NASA's Mars Odyssey orbiter. Each as large as a football field, they may be openings into natural caves below the Martian surface. "If there is life on Mars, there is a good chance you'd find it in caves," said Jut Wynne, one of the researchers who noticed the features while working on a US Geological Survey Mars Cave Detection Program. Jonathan Clarke, a geologist with the Mars Society of Australia, yesterday described the discovery as exciting. One photo taken at night by an infrared imager showed one hole to be unusually warm, suggesting hot air trapped during the day is flowing out. "I said: 'Wow, that's a cave'" Dr. Clarke said excitedly. "People have been looking for these for a long time; now we have found them." He agreed such caves would be perfect places to hunt for life escaping from the bitterly cold, radiation-soaked , dry surface. "Tiny drops of water could collect inside," he said. "If there are gases coming out, they could provide energy for a whole range of bacteria. A cave is also a protection from radiation; the surface of Mars is exposed to high levels of space radiation." The caves probably formed when tube-shaped lave flows spread across the planet long ago. The outside of the tubes cooled, forming solid walls, while something hotter inside allowed the remaining have to flow out, forming caves.
Ans: Question: We can learn from the passage that_.Options:A water has already been found on MarsB the scientists found all the caves at nightC it is certain that there is life in these cavesD the surface of Mars is bitterly cold, radiation-soaked and dryAnswer:D
