Article: Once Dr. Mellinkoff invited me to join him at the hospital to discuss interesting cases(, ) with his students.The case at hand was a Guatemalan man, aged 34, who had a fever and many other medical problems.His condition was not improving, and there was not much hope he would live. Dr.: Mellinkoff asked to see the patient.He introduced himself in Spanish and, in a very gentle voice, asked how he felt.The patient smiled and said everything was all right.Then the doctor asked if he was able to eat.The patient said that he had no desire to eat. "Are you getting food you like?" The patient said nothing. "Do you get the kind of food you have at home?" The answer was no. The doctor put his hand on the man's shoulder and his voice was very soft. "If you had food that you liked, would you eat it?" "Yes, yes," the patient said. The change in the patient's appearance couldn't have been more obvious.Nothing was said, but it was easy to tell that a message had been sent and had also been received. Later, the doctor asked why the Guatemalan man wasn't getting food he could eat.One of the students said, "We all know how difficult it is to get the kitchen to make special meals." "Suppose," the doctor replied, "you felt a certain medicine was absolutely necessary but that our hospital didn't carry it, would you accept defeat or would you insist the hospital meet your request?" "I would probably insist," the student said. "Very well," the doctor said."You might want to try the same method in the kitchen.It won't be-easy, but I can help you.Meanwhile, let's get some food inside this man as fast as possible, and stay with it.Or he'll be killed by hunger.By the way, there must be someone among you who can speak Spanish.If we want to make real progress, we need to be able to talk with him." Three weeks later.Doctor Mellinkoff told me that the Guatemalan man had left the hospital under his own power.It takes more than medicine to help sick people; you also have to talk to them and make them comfortable.

Article: Head held high, hands firmly gripping her walker, Mary Arnott, 99, walks slowly with dignity through the women's changing room at the Etobicoke Olympium pool, past the teenage girls who have been blow-drying their hair for half an hour, into the mist of the showers, then out the door and first one into the heated pool. She jumps over to the shallow end, stopping to talk to friends--everyone knows Arnott here; she swims twice a week and treats it as a job--about their children, the viciousness of bridge and their health. In fact, Arnott is an exception to the exception. Not only has she lived 20 years past the average lifespan for Canadians, she's healthy, her mind is sharp and she lives independently. Born in Brooklyn on May 28, 1909, Arnott was raised on Staten Island. She survived scarlet fever , helped bring up four siblings after her mother died in 1923 and worked as a secretary in New York City for 12 years, earning$35 a week and a$150 bonus at Christmas. Now she's happy living in a one-room apartment with a kitchen and a bathroom in her daughter's house. She wears a hearing aid, does the cryptic crossword with a magnifying glass, and can't really explain why she has live so well so long. Until recently, she has still liked to drink red wine--she used to drink two glasses before supper each day. It's more likely genes, she admits. Her interest in other people and life in general may have had something to do with it. Asked if a star photographer can take her picture at the pool, Arnott seems cheerful. "I look good in a swimsuit," she says, nodding her head firmly. "I look better in a swimsuit than I do in pants. "

Article: Scientists have created a " human-like robot" that can dance and do the housework. " Mahru" has been developed to imitate humans and can move its lips, eyebrows and pupils . The machine can also move its upper and lower body freely and automatically stop itself when walking. In addition, it has been programmed to give out two kinds of pleasant smells to match its emotions. The 1.5 tall robot was produced by researchers at the Korea Institute of Science and Technology (KIST) and is the first South Korean- developed machine of its kind. "'Mahru' will open the way for the commercial use of humanoid robots doing housework," You Bum-Jae, leader of the development research team ,said. "'Mahru' can dance while walking on its legs and is able to work in place of a human." Through an advanced motion capture system, "Mahru" can follow a variety of human movements and move its hands freely enough to deal with any obstacles that may get in its way when walking. State-funded KIST showed the robot during a presentation at its head office in Seoul. People here were treated to an entertaining demonstration which saw the robot show off the full range of its skills, most notably s series of dance moves. The research team added that they had designed another " Mahru", this time with sensors allowing it to distinguish between faces and objects. The showing of " Mahru" came a week after researcher in Japan said they had created the "most human-like" robot in the world. A team at robotics department of Osaka University in Japan claimed that " robogirl", Repliee R-1, " looks, moves and interacts like a human, and has silicone skin that feels almost human to the touch."
Question: "Mahru" made by KIST can do the following things EXCEPT _
Options: (A) dance with other human -like robots (B) move its body freely (C) stop automatically when walking (D) express certain feelings through smells
