user: input question: Write a multi-choice question for the following article, with the given choices and answer: Article: At first sight the planet Mars does not appear very welcoming to any kind of life. It has very little oxygen and water, the temperature at night is below 50 degrees and winds of 100 miles (161 kilometers)per hour cause severe dust storms. However, the surface of the planet seems to show that water flowed across it at some time in the past, and it is believed that there would be enough ice at the poles to cover the planet with water if it melted. Although there is no life on the Mars now, some scientists think there may have been some form of life a long time ago. At that time, the planet had active volcanoes ; the atmosphere was thicker and warmer; and there was water. In fact, in some ways the Mars may have been similar to the Earth, where life exists. Some people believe that the Mars could support life in the future if the right conditions were produced. The first step would be to warm the planet using certain gases which trap the Sun's heat in the planet's atmosphere. With warmth, water and carbon dioxide , simple plants could begin to grow. These plants could slowly make the Mars fit to live on. It is judged that the whole process might take between 100, 000 and 200, 000 years. In the meantime, people could begin to live on the planet in a special closed environment. They would provide a lot of useful information about conditions on Mars and the problems connected with living there. Options: A No Life on Mars B A Study of Mars C The Future conditions on Mars D The Possibility of Life on Mars Answer: D The Possibility of Life on Mars Question:???

Write a multi-choice question for the following article, with the given choices and answer: Article: Big trees are incredibly important ecologically. For a start, they provide food for countless other species and shelter for many animals. With their tall branches in the sun, they capture vast amounts of energy. This allows them to produce massive crops of fruit and flowers that sustain much of the animal life in the forest. Only a small number of tree species have the genetic ability to grow really big. The biggest are native to North America, but big trees grow all over the globe, from the tropics to the forests of the high latitudes  . To achieve giant size, a tree needs three things: the right place to establish its seedling, good growing conditions and lots of time with low adult death rate. Lose any of these, and you will lose your biggest trees. In some parts of the world, populations of big trees are dwindling  because their seedlings cannot survive. In southern India, for instance, an aggressive non-native bush, Lantana camara, is invading the floor of many forests. Lantana grows so thickly that young trees often fail to take root. With no young trees to replace them, it is only a matter of time before most of the big trees disappear. Without the right growing conditions, trees cannot get really big and there is some evidence to suggest tree growth could slow in a warmer world, particularly in environments that are already warm. Having worked for decades at La Selva Biological Station in Puerto Viejo de Sarapiqui, Costa Rica, David and Deborah Clark and colleagues have shown that tree growth there declines markedly in warmer years. "During the day, their growth shuts down when it gets too warm, and at night they consume more energy because their metabolic   rate increases," explains David Clark. With less energy produced in warmer years and more being consumed just to survive, there is even less energy available for growth. The darks' theory, if correct, means tropical forests would shrink over time. The largest, oldest trees would progressively die off and tend not to be replaced. According to the... Options: A Big trees in trouble. B Advantages of big trees. C Results of big trees' disappearing. D Importance of big trees to humans. Answer: A Big trees in trouble. Question:

Q: Write a multi-choice question for the following article, with the given choices and answer: Article: A drink of water is just a matter of turning on a tap for most of us. However, water for those in drought-stricken northwestern China can't be taken for granted. Its present shortage is a matter of life and death to them. The tragedy is the direct result of the drought that has hit a large area of northwestern China, and is affecting more than 50 million people.  The drought began last spring, ravaging Gansu, Qinghai and Shaanxi. Experts say the drought is a result of less rainfall, insufficient water reserves, high temperatures, dated irrigation projects, environmental damage and global climate change. More than 15 million people are having difficulties getting safe drinking water. The drought is also affecting schoolchildren's studies. "I am worried that my family will get no harvest this year. In that case, my family will not be able to afford my living costs," an unnamed boarding schoolgirl at Naqing Primary School in Shandan, Zhangye, told Dazhong Daily. But thanks to measures taken under the leadership of the central government, the drinking water problem has been greatly eased. Each person in the five worst-hit provinces is being supplied with drinking water and 20 liters of water for other purposes each day. Local authorities are digging deep wells and creating artificial rain. Military personnel are helping to transport water from others province to Gansu and Qinghai, according to CCTV. In Shaanxi, locals are turning to drought resistant crops. Other parts of China are helping by giving water and donating other resources. Options: A causing many to die of thirst B making it hard for millions to get drinking water C making it difficult for school children with parents facing money problems D destroying the harvest Answer: A causing many to die of thirst Question:
A: The damages the drought brought about are the following EXCEPT_.


Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: Not all bodies of water are so evidently alive as the Atlantic Ocean, an S-shaped body of water covering 33 million square miles. The Atlantic has, in a sense, replaced the Mediterranean as the inland sea of Western civilization. Unlike real inland seas, which seem strangely still, the Atlantic is rich in oceanic liveliness. It is perhaps not surprising that its vitality has been much written about by ancient poets. "Storm at Sea", a short poem written around 700, is generally regarded as one of mankind's earliest artistic representations of the Atlantic. When the wind is from the west All the waves that cannot rest To the east must thunder on Where the bright tree of the sun Is rooted in the ocean's breast. As the poem suggests, the Atlantic is never dead and dull. It is an ocean that moves, impressively and endlessly. It makes all kinds of noise--it is forever thundering, boiling, crashing, and whistling. It is easy to imagine the Atlantic trying to draw breath--perhaps not so noticeably out in mid-ocean, but where it meets land, its waters bathing up and down a sandy beach. It mimics  nearly perfectly the steady breathing of a living creature. It is filled with _ existences, too: unimaginable quantities of creatures, little and large alike, mix within its depths in a kind of oceanic harmony, giving to the waters a feeling of heartbeat, a kind of sub-ocean vitality. And it has a psychology. It has personalities: sometimes peaceful and pleasant, on rare occasions rough and wild; always it is strong and striking. Options: A To describe the movement of the waves. B To show the strength of the storm. C To represent the power of the ocean. D To prove the vastness of the sea. Answer: C To represent the power of the ocean. Question:
