input question: Write a multi-choice question for the following article, with the given choices and answer: Article: As Artificial Intelligence(AI) becomes increasingly sophisticated, there are growing concerns that robots could become a threat. This danger can be avoided, according to computer science professor Stuart Russell, if we figure out how to turn human values into a programmable code. Russell argues that as robots take on more complicated tasks, it's necessary to translate our morals into AI language. For example, if a robot does chores around the house, you wouldn't want it to put the pet cat in the oven to make dinner for the hungry children. "You would want that robot preloaded with a good set of values," said Russell. Some robots are already programmed with basic human values. For example, mobile robots have been programmed to keep a comfortable distance from humans. Obviously there are cultural differences, but if you were talking to another person and they came up close in your personal space, you wouldn't think that's the kind of thing a properly brought-up person would do. It will be possible to create more sophisticated moral machines, if only we can find a way to set out human values as clear rules. Robots could also learn values from drawing patterns from large sets of data on human behavior. They are dangerous only if programmers are careless. The biggest concern with robots going against human values is that human beings fail to so sufficient testing and they've produced a system that will break some kind of taboo . One simple check would be to program a robot to check the correct course of action with a human when presented with an unusual situation. If the robot is unsure whether an animal is suitable for the microwave, it has the opportunity to stop, send out beeps , and ask for directions from a human. If we humans aren't quite sure about a decision, we go and ask somebody else. The most difficult step in programming values will be deciding exactly what we believe in moral, and how to create a set of ethical rules. But if we come up with an answer, robots could be good for humanity. Options: A Determine what is moral and ethical. B Design some large-scale experiments. C Set rules for man-machine interaction. D Develop a more sophisticated program. Answer: A Determine what is moral and ethical. Question:???
output answer: What is most difficult to do when we turn human values into a programmable code?

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Death Valley is a land of beautiful yet dangerous extremes. Death Valley can be dangerously cold during the winter months. Storms in the mountains can produce sudden flooding on the floor of the Valley. The air temperature during the summer has been as high as fifty- seven degrees Celsius. The sun can heat the ground so that the temperature of the rocks and soil can be as high as seventy -four degrees Celsius. Death Valley contains evidence of several ancient volcanoes that caused huge explosions. Evidence of one of these explosions is called Ubehebe Crater. The explosion left a huge hole in the ground almost a kilometer and a half wide. In many areas of Death Valley it is easy to see where the ground has been pushed up violently by movement deep in the Earth. This movement has created unusual and beautiful rock formations. Some are red. Others are dark brown, gray, yellow or black. The area was named by a woman in 1849. Thousands of people from other parts of the ountry traveled to the gold mining areas in California. They were in a hurry to get there before other people did. One group trying to reach California decided to take a path called the Old Spanish Trail. By December they had reached Death Valley. They did not have to survive the terrible heat of summer, but there was still an extreme lack of water. There were few plants for their work animals to eat. The people could not find a pass through the tall mountains to the west of the Valley, Slowly, they began co suffer from a lack of food. To survive, they killed their work animals for food and began to walk out of the Valley. As they left, one woman looked back and said, "Good -bye, death valley. " The name has never been changed. Almost everyone who visits Death Valley visits a huge house called Scotty' s Castle. The building design is Spanish, with high thick walls to provide protection from the fierce heat. The castle is named for Walter Scott , called Scotty. by his friends. He was a gold miner. He told everyone that he built the house with money... Options: A the interesting place in Death Valley B the facts about Death Valley C the origin of Death Valley D the route to visit Death Valley Answer: B the facts about Death Valley Question:???
output answer: The main idea of the passage is about _ .

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Something's not quite right with the climate.While global CO2emissions have continued to swell, the global temperature rise has leveled off.Meanwhile, satellites and other observational tools indicate that the net heat retained by the planet has continued to increase, and that excess energy should be pushing up surface temperatures.But it's not. In fact, up to half the heat energy that was expected to fuel global wanning since 2003 has gone " missing.M Kevin Trenberth and John Fasullo of the National Center for Atmospheric Research ( NCAR) wonder where that heat may have gone--and what it could mean for the future of the climate. One possibility is that some of our measurements could be off.Although scientists have a lot of confidence in their ability to measure CO2buildup and the energy balance in the atmosphere--the data used in the measurements comes from multiple sources, all of which, Fasullo says, "tell the same story"--our data on ocean temperatures isn't as good."Keeping track of temperature over the whole oceans isn't that easy," says Fasullo. So, it is likely that the missing heat is being trapped deep in the ocean, well below the 900m to 1,500m range of our surface sensors.But despite their vastness, the deep oceans have a limit, says Fasullo, who thinks they won't behave as a heat sink over the long term."That's not what we've seen over long time scales in the past," he says."We clearly know the ocean can't absorb the heat indefinitely. Overall, the missing heat doesn't change expectations for future climate change, because the heat won't stay missing forever.Eventually it will resurface and impact the climate system, and the recent and deceptive reprieve from rapid warming we've enjoyed will come to an expected end.When that will happen is unknown, but better science can give us a clearer idea."At the end of the day, the system will come back to balance, and that suggests temperature will end up increasing," says Fasullo.So it's still up to us to do something about it. Options: A It may hide in our natural environment. B It has sunk into ocean over the long term. C It may be absorbed by large number of forests. D It may be absorbed by deep ocean temporarily. Answer: D It may be absorbed by deep ocean temporarily. Question:???
output answer:
Where is the missing heat likely to hide, as Fasullo expects?
