TASK DEFINITION: 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.
PROBLEM: 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.

SOLUTION: When will the six volunteers end their mission about mimicking life on Mars?

PROBLEM: Article: Charles Dickens was one of the most beloved storytellers in the English language. His novels made him famous in his own time, and continue as classics in ours. Dickens began his literary career with almost no formal education. He was born in Landport, on Feb. 7, 1812, the second of eight children. When he was 12, his father was sent to debtor's prison. Dickens was forced to quit school and work in a London blacking factory. He would rework that terrible experience into his fiction for the rest of his life. "He was a social reformer," says actor Simon Callow, author of a new biography called Charles Dickens and the Great Theatre of the World. "He knew what poverty was. He knew what it was to be rejected, to be cast aside, to live in squalor ." And so Dickens wrote with great sympathy for the suffering of innocent and vulnerable children - characters like David Copperfield, Little Dorrit and the orphan, Oliver Twist: With his slice of bread in his hand, and his little brown parish cap on his head, Oliver was now led away from the wretched home, where one kind word or look never lighted the gloom of his infant days. Yet he burst into an agony of childish grief as the cottage gate closed after him. Wretched as were the little companions in,misery he was now leaving behind him, they were the only friends he had ever had. His first book Sketches by Boz came out in 1836. With the appearance of Oliver Twist in London periodicals in 1837, the 25-year-old Dickens became the most popular writer in England. But his first love was theater, and he considered becoming an actor. "When he was actually writing, he became his characters," says Peter Ackroyd, author of Dickens: Public Life and Private Passion. "He would get up from his desk, go over to the mirror and mouth the words - do the expressions, grimaces , whatever, and then laugh, chuckle to himself, then go back to his desk and write it down." Dickens created 989 named characters, which increased his popularity. Every one of his major works has been adapted for either stage or screen. A Christmas Carol inspired more than a dozen films, from Alistair Sims' Scrooge in 1951 to Jim Carrey's voicing of the same character in Disney's 2009, 3-D animated film. The original 1843 manuscript of A Christmas Carolis on display at the Morgan Library. Dickens wrote everything by hand, in tiny script, with a quill pen. Remarkably, the manuscript is both the first and the final draft, says Kiely, the curator. You can see where Dickens has changed the name of the first chapter from "Old Marley's Ghost" to "Marley's Ghost". Further down the page, he has canceled an entire section. "He realizes he's not writing a novel, and he only has a very short time in which to write this," Kiely explains. "He's got to keep it tight, in order for it to be published in time for Christmas." Dickens wrote all the time. He traveled with a portable inkwell and a supply of quill pens. He was working on his last novel, Our Mutual Friend, en route from France to London when the train he was on crashed. Dickens died five years later in 1870, after a stroke at age 58. As a comic talent and a social reformer, Dickens' achievement was extraordinary, says novelist T.C. Boyle, who eamed a doctorate in Victorian literature. "He achieved what any great artist achieves - a body of work that has entertained and delighted and instructed people down through the ages. That's what we all hope for," says Boyle. But Dickens' greatest fiction was his own character, says Callow, the biographer: "People think of him as a cheerful man ... but he was increasingly suffering from depression and a sense of hopelessness. And that's worth knowing. I think it's always good to know that great creative individuals have their struggle, their drama."
Answer: His childhood sufferings.

SOLUTION: What can probably be reflected in Dickens' works?

PROBLEM: Article: Howling is a behavior commonly observed among a wolf nark. An animals, wolves work together to hunt and rely on howling was an important means of communication each other. There are different explants of a wolf's howl and it appears that there may be more to discover. One theory is that wolves howl to bend better together. It's almost as if howling together helps the pack stay together. Perhaps something similar to people feeling a sense of involvement with each other when singing a song together . But this theory may be wrong, explains Fred H. Harington, a professor who studies wolf behavior. Indeed, there have been tines when wolves have been seen one moment howling in a exhorts, and the next, quarreling anions each other. It appears that usually the lowest-tanking menthes of the pack may actually be "punished" for Joining in the churs at times. So is howling a way to strcagthen a social boad or just a way to reconfirm status among its members? ----Why do welves howl for sure? What is cleat, however, is that howling is often used among packmates to locate each other. Hunting grounds are distant and it happens that woloves may separate from one another at times. When this happens, howling appcars to be an ercellent means of gathering. Howling, interestingly, is a contagious behaviour. When one wolf starts to howl, very likely others will follow. This is often seen to occat in the morning, as if wolves were doing some sotr of "roll rall"where wolves all howl togeter to howl, very likely others will follow.
