Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: Have you ever dreamed of visiting a planet in the Milky Way? While the trip sounds exciting, it would take years and years to reach the place that we are going to. So in the future, bedtime for astronauts may be more than a few hours of regular shut-eye. They would have to sleep for years. European researchers are now doing hibernation experiments. The study may help them understand whether humans could ever sleep through the years it would take for a space flight to distant planets. "If there was an effective technology, it could make deep-space travel come true," said Mark Ayer of the European Space Agency last month. What seems like science fiction is not completely impossible. Researchers have been able to use chemicals to put living cells into a sleep-like state where they don't age. They have now moved on to small, non-hibernating mammals like rats. The results will be out soon. A major challenge is the fact that cells can be very simple systems, but body organs are far more complex . "It's like moving from a simple Apple computer to a supercomputer," said Marco Biggiogera, a hibernation researcher at Italy's University of Pavia. Just like bears and frogs, the hibernation of human beings would cause a person's metabolism to lower so they would need less energy. Medical research, however, is just half of a space flight hibernation system. There is the challenge of designing a suitable protective place to live. Such a place would provide the proper environment for hibernation, such as the proper temperature. It would also have to monitor life functions and serve the physiological needs of the hibernator. According to Ayer, the six-person Human Outer Planets Exploration Mission to Jupiter's moon Callisto, could be an opportunity to use human hibernation. The mission aims to send six humans on a five-year flight to Callisto, where they will spend 30 days, in 2045. , . Options: A Hibernation study for space travel B Welcome to our space travel C To hibernate, to live longer D Welcome to the Milky Way Answer: A Hibernation study for space travel Question:

A: What's the best title for the passage?

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: What would you do if you found a snake in your house? Many people might be afraid or try to kill it. However, if you live in North Carolina in the USA, one thing you can do is to call the Snake Catchers. The Snake Catchers are four men who love snakes, even poisonous ones. Their newspaper advertisement says, "Snake Catchers: free snake removal Please do not kill them -- Call us. " The Snake Catchers, who started their service in 1998, don't charge anything for helping people. "We do this as a hobby," explained Fred Johnson, one of the Snake Catchers. Because of their love of snakes, the Snake Catchers try to keep them alive. "One man asked us to kill a python , so he could make a pair of boots from the skin. We refused, because we like snakes, and we don't want to see them killed, " said Fred. Some of the snakes that they catch are kept as pets; some are given to the North Carolina State University. Most, including the poisonous snakes, are set free in the wild, usually in a national park. Fred suggests that people should treat snakes with care. "Actually snakes are very shy and gentle creatures. They only attack if they are frightened. However, you have to know how to treat a snake properly!" According to one happy family, the Snake Catchers are good. One day, the Greenwood family found a snake skin in the kitchen. They looked very carefully and saw a snake sleeping behind a cupboard. They thought about what to do. Then Steve Greenwood remembered the advertisement for the Snake Catchers. He called them. "The Snake Catchers arrived within an hour and they finished the job quickly too," said Steve Greenwood. "One of them went into the kitchen, found the snake and took it out alive. The Snake Catchers did a very good job." Last year, the Snake Catchers removed more than seventy snakes from houses in North Carolina. Options: A in a national park B in a university C in a garden D in their own houses Answer: A in a national park Question:

[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: What's the red star in the sky through a telescope ? It is Mars. Do you want to know more about it? Take the "Mars Orbit Express"! "Mars Orbit Express" is a space probe . It was sent towards Mars by American scientists on August 12th,2005. Its tasks are to study Mars' atmosphere and return photos to Earth. But before that "Mars Orbit Express" must travel about 100 hundred million kilometers and seven months. It reached Mars' orbit in March,2006. Mars and Earth have similar weight and size. However,Mars is closer to the sun than Earth. Mars is very cold. The average temperature is below 50degC. The temperature at noon only reaches 20degC during a Mars day. Its atmosphere is mostly CO2. It has much sand and two moons---Phobos and Deimos. Scientists think Earth and Mars had similar beginnings 4.6 billion years ago. But while Earth supports millions of lives,Mars becomes bad. "Earth easily could have turned out like that." said an scientist, "It is important for us to find out why and Mars Orbit Express' should do that." "Mars Orbit Express" also would help scientists to learn what might happen to Earth in the future. "Mars Orbit Express" would work for about four years. Options: A taking pictures of Mars B studying the weight of Mars C finding out distance between Earth and Mars D telling the time it takes to go from Earth to Mars Answer: A taking pictures of Mars Question:

[A]:
One of the tasks of Mars Orbit Express is _ .
