input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: Experts have put forward detailed plans for a tunnel to join Taiwan with the Chinese mainland. The shortest proposed route would be 126 kilometers--more than twice the length of the English Channel Tunnel.And the longest proposed route would be 207 kilometers. A recent conference in xiamen,Fujian Province brought together more than 70 experts.The event was cosponsored by universities from Taiwan and the Chinese mainland.Fujian is the province where both proposed mutes would begin. There is no direct passenger access between the mainland and Taiwan by air or sea at the moment. Experts say that it is better to start research sooner rather than later,although there is a lack of government funding .There are no technical problems t0 build a Taiwan tunnel.But it will require an improved political relationship across the Straits. A professor of TsinghHa University said,"A special feature of huge projects is that the period of preparation is longer than the period of construction." For example,he said,the English channel Tunnel took 14 years of planning and had been discussed for two centuries.And preparations for the huge Three Corges dam on the Yangze River began in the 1950s. The xiamen conference focused on the longest southern route,which would use the Taiwan-controlled islands of Jinmen and Penghu as steppingstones. The first stage of the new project could be a bridge to cross the five kilometers between Xiamen and Jinmen.This would mean that traveling from Xiamen to Jinmen by car would only take five minutes. The longest tunnel now being planned anywhere in the world is the 54-kilometer land tunnel to link Lyon in France with Turin in Italy.The tunnel will not be completed until 2015-2020. Options: A The English Channel Tunnel. B The tunnel between Lyon and Turin. C The prefix = st1 /Taiwanstraits tunnel _ D The passage doesn't mention it. Answer: D The passage doesn't mention it.

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:
