[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: Beavers are a very unique species in the world of nature and wildlife----they are architects. Their dams are fine examples of engineering. A pair of beavers will build a dam, using branches, mud and stones, across a river. The water held back by the dam flows over the bank on either side of the river, flooding the nearby ground and forming a pond. At some point in the pond the beavers then build their home, which is called a lodge. This consists of a cone-shaped pipe of branches and sticks of two to six feet in length held together with mud and stones, the top of which projects above the waterline. It serves as a shelter from the bad weather, a safety from enemies and a base for food supplies to be drawn upon in winter. From an engineering point of view the lodge could hardly be improved. Not only does it contain a central room just above water level, which is accessible only through underwater tunnels, but it also has "walls", one or more escape tunnels and an air hole at the top, which controls the temperature inside and gives air-conditioning. It is altogether a clever piece of construction, with all modern conveniences. It is, in fact, better protected against the effects of flooding than many human houses. Trees are essential to beavers. They eat the bark on the upper branches. But they must first _ the trees, using their four front teeth. With these sharp tools, it takes only a few minutes to cut down a tree. The engineering skill of beavers is to a large extent a result of their ability to use their front paws as hands. A female will carry her young held under her chin with her front paws, walking on her hind legs. A similar method is used by all beavers when transporting stones or mud, although they also carry such materials on their broad flat trails. The fore-paws are also used for digging and for dragging heavier pieces of wood. Options: A the beaver's lodge B the beaver's engineering skills C the beaver's dam D the beaver's intelligence Answer: B the beaver's engineering skills Question:

input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: ,. Three-year-old Teddy Lasry was sleeping in his cowboy outfit yesterday at his family's Fifth Ave.apartment when he shot up in bed screaming.A 3-foot-long black-and-white snake twisted around his left arm and had just bitten his little finger. "The babysitter (a person taking care of children while their parents are away for a short time) was frightened to death," said Teddy's father, David Lasry, who, along with his wife, Evelyn, was at work when the snake appeared about 4:00 pm. The horrified babysitter called 911 and the building's doorman.The doorman and two cable TV workers helped take the snake off the boy's arm and put it in a garbage bag.Police rushed Teddy to Mount Sinai Medical Center, where he spent two hours attached to a heart monitor as a precaution in case the snake was poisonous.It wasn't.Experts at the snakebite treatment center at Jacobi Medical Center in the Bronx, where policemen took the snake, found out it was a non-poisonous California king snake. But how did it end up in Teddy's bed? A little detective work determined that the snake had escaped two weeks ago from its cage in the apartment of a doctor whose family lives four floors below the Lasrys.The apologetic owner said his son's pet snake likely traveled up the water pipes and into his neighbor's apartment."It's a very gentle, very harmless snake," he said."It's handled by our family all the time." David Lasry believed the pet was simply hungry after two weeks of wandering.Evelyn said her son seems to have overcome his fright by thinking of himself as a hero cowboy as he rode in the back of the police car to the hospital. "I told Teddy he's a pretty snake, a nice pet snake who got out of his cage," Evelyn said."But he asked, 'Why did he bite my finger, Mamma?' And I said, 'Because he saw that you are a big boy, Teddy, in your cowboy outfit and he got scared.'" Options: A his parents weren't at home B he was asleep the snake C was scared of him D the snake was hungry Answer: C was scared of him Question:

output: Teddy probably believed he was attacked because _ .

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: Qian Xuesen is one of the pioneers of China's space science. As a world-famous expert on aerospace rockets and aerodynamics, he obtained great achievements in the areas of applied mechanics, engineering cybernetics and system engineering and made distinguished contributions to the foundation and development of Chinese aerospace undertaking . He graduated from Shanghai Jiaotong University in 1934, and Qian Xuesen went to the United States to study in MIT, Massachusetts Institute of Technology, one year later. After receiving master's degree in MIT, he went to study in California Institute of Technology and received PhD degrees in both aerospace and mathematics. In 1955, six years after the founding of People's Republic of China, Qian Xuesen returned to his motherland. His return brought China the hope of developing space science and its own missiles. In 1956, Qian Xuesen put forward "Proposal on the Development of China's Aviation Industry for National Defense". With the support from Zhou Enlai, the premier, and marshal Nie Rongzheng, Qian Xuesen began to prepare for the establishment of China's first missile and rocket research and development structure, the Fifth Research Institute of State Ministry of Defense. Henceforth , he has long been in charge of the chief technological research and development of China's missile, rocket and spacecraft. Due to research and development led by Qian Xuesen, China successfully exploded its first atom bomb in 1964. Later, China launched its first man-made satellite, Dong Fang Hong I, to the earth orbit on April 24, 1970, becoming the fifth country in the world to independently launch satellite following the former Union of Soviet Socialist Republics, the USA, France and Japan. The satellite floated around the earth, blaring the song Dong Fang Hong, which has the same name as the satellite. As a _ leading the development of China's aerospace science and technology, Qian Xuesen also provided chances for young scientists. Wang Yongzhi, former chief designer of China's... Options: A In 1956, he made good preparations for the Fifth Research Institute of State Ministry of Defence. B He made outstanding contributions to the establishment and development of Chinese aerospace undertaking. C He returned to China, bringing China the hope of developing space science and its own missiles. D He devoted all his life to China's space science. Answer: A In 1956, he made good preparations for the Fifth Research Institute of State Ministry of Defence. Question:
