Do not generate anything else apart from one of the following characters: "A", "B", "C", "D". There is only one correct answer for each question.
PROBLEM: Article: In the near future,we may be using our eyes to operate our smart-phones and tablets,even when it comes to playing popular games like Fruit Ninja. The Gaze Group has been developing eye-controlled computer technology for nearly 20 years.But those devices have been firstly designed to help those with disabilities,and are very expensive. "After a while,we figured out that probably the best way is to go for a mass-market way," says Gaze's Sune Alstrup Johansen."where everybody would have this available." Johansen and some of his colleagues have formed a new company,the Eye Tribe,which is hoping to develop the technology on a mass commercial level. The technology works with the help of the computing device toward the user's face. After making sure of the user's eye movements,the technology is then able to easily find where a person's eyes are moving,and then allow the eyes to control a cursor . "Our software can then determine the location of the eyes and know where you're looking on the screen to make sure what you're looking at,"reads an explanation on the Eye Tribe site. There has been a gradual change toward hands-free technology in recent years, particularly in the gaming world.Recently Xbox released the Kinect device,which lets users control their Xbox and play certain games using only their hands,legs and voices. But still,most of these devices have been more of a _ than a practical way to use one's hands to control a mobile device.Johansen said a replaceable filter would be a cheap,convenient way for most consumers. And even as companies like The Eye Tribe work to create such a product for the average user, making the eye-controlled technology more accessible and less expensive will have similar benefits for physically disabled users.

PROBLEM: Article: Growing in Philadelphia, Lieberman started cooking with his stay-at-home dad when he was seven. His food-loving family had two kitchens, and quickly learned what was the best way to bake his cakes. Lieberman improved his kitchen skills greatly during a year abroad before college, learning from a cook in Italy and studying local specialties in Germany, Spain and France. At Yale, he was known for throwing dinner parties, single-handedly frying and baking while mixing drinks for dozens of friends. Just for fun, he and some friends decided to tape a show named Campus Cuisineabout his cooking. Lieberman was a real college student showing his classmates how to do things like make drinks out of dining-hall fruit. That helped the show become very popular among the students. They would stop Lieberman after classes to ask for his advice on cooking. Tapes of the show were passed around, with which his name went beyond the school and finally to the Food Network. Food Network producer Flay hopes the young cook will find a place on the network television. He says Lieberman's _ is key."Food TV isn't about food anymore,"says Flay."It's about your personality and finding a way to keep people's eyeballs on your show." But Lieberman isn't putting all his eggs in one basket. After taping the first season of the new show, Lieberman was back in his own small kitchen preparing sandwiches. An airline company was looking for someone to come up with a tasteful, inexpensive and easy-to-make menu to serve on its flights. Lieberman got the job.

PROBLEM: Article: In 1880, fourteen-year-old Matthew Henson loved to hear sailors tell tales of their exciting lives at sea. The travel, the adventure, the danger, and the steady pay were all attracting young Henson. One day, he found a job as a cabin boy on a beautiful ship called the Katie Hinds. For the next five years, Henson sailed around the world. With the help of the ship's captain and other members of the crew, Henson learned mathematics, navigation, history, geography, and many other subjects. By the time he left the Katie Hinds in 1885, Henson was well educated and had become an excellent seaman. Unable to find work anywhere else, Henson took a job in a hat shop in Washington, D.C. One day in 1887, a man came in to buy a hat. The man, Robert Peary, asked the owner if he knew anyone with experience at sea. Peary would soon travel to South America for the U.S. government. He needed experienced men to accompany him. The shop owner knew about his young employee's skills and experience on ocean journeys, so he introduced Peary to Henson. Using his map-reading and sailing skills, Henson proved himself to be a worthy and smart seaman. Peary soon made Henson his assistant, and they became close friends. One day Peary told Henson about his real dream: to be the first man to stand on "the top of the world" at the North Pole. He asked Henson to help him make his dream come true. Over the next five years, the two explorers made two trips together to the Arctic. However, they were not able to reach the pole either time. The cold, wind, and ice were worse than either of them had ever imagined. In 1908, Peary and Henson were ready to make their final attempt at reaching the North Pole. Both men were over forty years old. The years of hardship in the arctic cold had made them suffer a lot. This would be their last chance. With four Inuit guides, they made a mad rush straight across the ice toward the pole. Peary's feet were injured and he had to be pulled on a dogsled. In April 1909, Henson's instruments showed they were standing at the North Pole. Together Henson and Peary planted the American flag in the snow. In later years, Robert Peary and Henson were greatly honored for their achievements. Today, the two friends and fellow explorers lie in heroes' graves not far apart in the Arlington National Cemetery.
