In this task, you're given an article and an answer. Your task is to generate the question for the answer based on the given article.

Example Input: Article: What if you arrived home to find a delicious hot meal waiting for you,prepared by your very own kitchen robot? It might sound like science fiction,but professors at the university of Tokyo have taken the first steps toward making that scenario a reality.The team recently introduced a humanoid kitchen robot that can pour tea and other drinks into cups and serve them to guests.When teatime is over,the robot can also wash the dishes and put them away. In California,another interesting kitchen robot has been developed.Called the Readybot,it can pick up objects and either store them in cabinets or put them in the trash.It also carries a separate floor-cleaning robot that can operate by itself.Unlike the Japanese robot,Readybot is not humanoid.Instead,it looks more like a large box with arms and wheels. Readybot was created by engineers and designers who established a club called the Readybot Challenge.They believe that in the future millions of robots will be needed in homes to perform ordinary household tasks.Readybot is just the first step in their plan to create a robot that can tackle jobs not only in kitchens but in other rooms of homes and in offices as well. Clearly there are technological hurdles to overcome before robots can cook a complete dinner,and there are also many safety concerns.Not everyone(especially parents)would be comfortable with the idea of robots in their house,manipulating hot pans and sharp knives.The European Commission recently funded a project to study these concerns.
Answer: it looks more like a person than Readybot does.
Example Output: What does the writer imply about the Japanese robot?

Example Input: Article: Six volunteers are about to find out what it would be like to live on Mars without ever leaving the Earth. Three men and three women will spend eight months living in a special place on the side of a volcano in Hawaii. They are part of an experiment that is designed to mimic life on Mars. Their mission began on October 15, 2014. NASA says it could send astronauts to Mars as early as the 2030s. The mission would take more than two years, so NASA needs to know how people would react to living in a small group, isolated from the rest of the world, for such a long time. Some people may become depressed or bored living under those conditions. By studying people living in similar conditions here on Eares NASA hopes to learn how to choose the most suitable people for a space mission, and how to help them get along. They will live in a two-story building. The ground floor is about 86 square meters, roughly the size of a small two-bedroom apartment. It includes shared areas like kitchen, dining room, bathroom, laboratory and an exercise room. The upstairs is less than half the size of the downstairs. It contains another bathroom and six small bedrooms. The building is located in an abandoned quarry about 2,400 meters up the side of Mauna Loa, the second biggest volcano in the world. It is constantly monitored for signs of volcanic activity. NASA chose the location because the appearance looks very similar to Mars. To make it more like being on Mars in the future, they are only able to communicate by email during the experiment. Meanwhile, there will be a 20-minute delay between the time when a message is sent and that when it is received. When they go outside, they will have to suit up in full spacesuits, just as if they were on Mars. The commander is Martha Lenio, a 34-year-old Canadian. During the mission, she will run experiments on growing food. The other members have backgrounds in physics and so on. None of them are astronauts.
Answer: On June 15, 2015.
Example Output: When will the six volunteers end their mission about mimicking life on Mars?

Example Input: Article: Once upon a time, a man was walking on a mountain when he found an incredible cave with all kinds of treasure inside it. So he gave up his job, his home, and his friends, and spent all his time guarding the cave. He was so dedicated to it that he hardly ate or drank, and before long he fell ill. One day, when he could hardly move at all, he decided to share the treasure. He crawled into the cave to get a handful of jewels, but discovered, to his horror, that it was empty except for a small emerald . The man took it, and gave it to the first person he came by, a woman. Then an old man came by. "What bad luck!" the man said. "Just a moment ago I gave a woman the last of the treasure I was guarding." "Are you sure there is nothing left?" the old man asked. The man took him into the cave, where they found a chest with jewels and some bags of gold. The man was shocked, and the old man explained to him, "At last! At last someone has broken the spell of this cave. This is the Cave of Treasure, and you're the first to have passed its great test. Many have dedicated their lives to this cave, only to end up realizing there was nothing here..." "And why does this happen?" the man asked. "This magic cave has only as many riches as your own heart. When someone discovers it, the cave is filled with treasure, but later, when they have devoted themselves to guarding the treasure, their hearts empty, as does the cave. The only way to fill it is by filling your heart with all that is good, as you did by giving the woman that last jewel." From that day on, the man understood that it was better to share than to keep. Thanks to the cave and the old man, he became noble and generous.
Answer: Because he had to guard the treasure cave.
Example Output:
Why did the man give up his job, home and friends?
