input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Australia's koalas could be dying out within 30 years, unless urgent measures is taken to stop the losing in population, according to researchers. They say development, climate change and bushfires have all related to reduce the number of wild koalas sharply. The Australian Koala Foundation said a recent survey showed the population could have dropped by more than half in the past six years. Previous estimates put the number of koalas at more than 100,000, but the latest figures suggest there could now be as few as 43,000. The foundation collected field data from 1,800 sites and 80,000 trees to calculate the numbers. In one area in northern Queensland estimated to have 20,000 koalas a decade ago, a team of eight people could not find a single animal in four days of searching. The foundation said besides problems caused by cutting down forests, hotter and drier conditions because of global warming had reduced the nutritional value of their staple food, eucalyptus leaves, leading to poor nutrition for them. Koalas, which live in the forests in Australia's east and south, are very particular about what types of the leaves they eat. Foundation chief Deborah Tabart said: "The koalas are missing everywhere we look. It's really no tree, no me. If you keep cutting down trees you don't have any koalas."She is hoping the new figures will persuade the government's Threatened Species Steering Committee (TSSC) to list the koala as threatened. But committee chairman Bob Beeton said a decision was not likely recently and the koala's status as one of the country's favorite animals would not be a factor. "There's a number of species which are attractive and people have special feelings towards them. We don't consider that," Mr. Beeton was reported as saying by the AFP agency. Options: A the leaves koalas eat are losing nutritional value B koalas cannot get enough water to drink C koalas can hardly stand the hot weather D the leaves koalas eat cannot grow in hot weather Answer: A the leaves koalas eat are losing nutritional value Question:???
output answer: Global warming is an important cause of koalas' reduction because _ .

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Shopping is not as simple as you may think! There are all sorts of tricks at play each time we reach out for that particular brand of product on the shelf. Colouring, for example, varies according to what the producers are trying to sell. Health foods are packaged in greens, yellows or browns because we think of these as healthy colours. Ice cream packets are often blue and expensive goods, like chocolates, are gold or silver. When some kind of pain killer was brought out recently, researchers found that _ because they made the product look weak and ineffective. Eventually, it came on the market in a dark blue and white package--blue because we think of it as safe, and white as calm. The size of a product can attract a shopper. But quite often a bottle doesn't contain as much as it appears to. It is believed that the better-known companies spend, on average, 70 percent of the total cost of the product itself on packaging! The most successful producers know that it's not enough to have a good product. The founder of Pears soap, who for 25 years has used pretty little girls to promote their goods, came to the conclusion: "Any fool can make soap, but it takes a genius to sell it." Options: A The way to promote goods. B The discovery of a genius. C The team to produce a good product. D The brand name used by successful producers. Answer: A The way to promote goods. Question:???
output answer: Which of the following is the key to the success in product sales?

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: American author Mark Twain once noted that "life would be surely happier if we could only be born at the age of 80 and gradually approach 18." Twain's words were only one of many complaints about aging. The ancient Greek poet Homer called old age "hateful", and William Shakespeare termed it "terrible winter". Alexander the Great, who conquered most of the known world before he died around 323 B.C., may have been looking for a river that healed the of age. During the 12th century A.D., a king called Prester John ruled a land that had a river of gold and a fountain of youth. But the name linked most closely to the search for a fountain of youth is 16th-century Spanish explorer Juan Ponce de Leon. He thought it would be found in Florida. In St. Augustine, the oldest city in the U.S., there's a tourist attraction. It is said to be the fountain of youth that Ponce de Leon discovered soon after he arrived in what is now Florida in 1513. However, elderly visitors who drink the spring's water don't turn into teenagers. But the tale of the search for a fountain of youth is so appealing that it survives anyway, says Ryan K. Smith, a professor of history. "People are more attracted by the story of looking and not finding than they are by the idea that the fountain might be out there somewhere." Still, a few grains of truth have helped to support . Kathleen Deagan, a professor of archaeology, says a graveyard and the remains of a Spanish mission dating back to St. Augustine's founding in 1565 have been discovered near the so-called fountain of youth. Michelle Reyna, a spokesperson for the Fountain of Youth Archaeological Park in St. Augustine, says the fountain has been a tourist attraction since at least 1901 and may have been attracting visitors since 1860. Options: A how the fountain of youth came into being B why some famous people hate becoming old C how to remain young forever D whether the fountain of youth exists Answer: D whether the fountain of youth exists Question:???

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: A glass a day keeps obesity at bay.Alcohol has always been thought to cause weight gain because of its high sugar content,but new research suggests a glass a day could form part of a diet.Looking at past studies they found that,while heavy drinkers do put on weight;those who drink _ can actually lose weight. A spokesman for the research team at Navarro University in Spain says,"Light to moderate alcohol intake,especially of wine,may be more likely to protect against,rather than promote,weight gain".The International Scientific Forum on Alcohol Research reviewed the findings and agreed with most of the conclusions,particularly that current data do not clearly indicate if moderate drinking increases weight. Boston University's Dr.Harvey Finkel found that the biologic mechanisms relating alcohol to changes in body weight are not properly understood.His team pointed out the strong protective effects of moderate drinking on the risk of getting conditions like diabetes ,which relate to increasing obesity.Some studies suggest that even very obese people may be at lower risk of diabetes if they are moderate drinkers. The group says alcohol provides calories that are quickly absorbed into the body and are not stored in fat,and that this process could explain the differences in its effects from those of other foods.They agree that future research should be directed towards assessing the roles of different types of alcoholic drinks,taking into consideration drinking patterns and including the past tendency of participants to gain weight. For now there is little evidence that consuming small to moderate amounts of alcohol on a regular basis increases one's risk of becoming obese.What's more,a study three years ago suggested that resveratrol,a compound present in grapes and red wine,destroys fat cells. Options: A who produce wine B who have a drinking habit C who go on a diet D who are eager to lose weight Answer: B who have a drinking habit Question:???
output answer:
The passage is mainly for those _ .
