Article: Robots industry is developing so rapidly that there is no denying that we may one day find ourselves surrounded by robots. The humanoid (human like) robots with two legs such as Honda Motor Co. Ltd's ASIMO would likely have an easier time climbing up stairs inside homes than a robot that moves on wheels, developers say. But it will be some time before such devices make their way into people's homes. "They may look smart, but they are still quite stupid," Shimoyama said. "I don't think they will ever be as smart as humans." While safety is an obvious concern, robots also need to be sensitive to people's needs. Researchers at Fujitsu Frontech Ltd and Fujitsu Laboratories responsible for developing "Enon", a guide and patrol robot designed for use in shopping malls and corporate facilities , are working on this. Enon, which has a humanoid upper body but no legs, is equipped with a touch screen on its chest and space in its stomach to carry loads weighting up to 10 kg. In guide mode, it will check a newcomer and approach the person with a nod and a greeting: "Are you a visitor? Hello." Visitors requiring directions can point to icons displayed on Enon's chest screen. If the restroom icon is pressed, the screen will display a map that shows the way. The robot will then face and point in the direction of the restroom, although it won't actually walk the visitor there. Enon is now in use at four locations in Japan, including a shopping mall near Tokyo. The main goal is to make it more helpful for the elderly. "People who work in the transportation sector often ask whether we can build a robot that will find elderly people who look lost in train stations, and ask them if they are all right," said Toshihido Marita, director of Fujitsu Laboratories Ltd's autonomous system laboratory. "Actually that is hard to do, very hard," he said.
Question: The advantage of Honda Motor Co. Ltd's ASIMO is that _ .

Asnwer: C

Ex Output:
Yes

Article: My grandfather had a small farm where he raised beef and some grain for feed. He also worked diligently as a factory laborer and country pastor. He was a good neighbor and well-respected for honoring his word. When harvest time came, he'd piece together his old one-row corn picker and oil it up for the season. All his life he worked hard, helped others, and you could count on him to keep his promises. He had promised to harvest a few ribbons of corn on a friend's farm, but after harvesting his own corn, Grandpa's little corn picker coughed and quit. It would be out of commission until a particular part could be ordered, but that would take far too long to help this year. The factory where Grandpa worked began to require overtime. In order to keep his job there he had to leave the farm before dawn and get home until well after sunset. One autumn night, while harvest time was running out, he and his wife sat at the kitchen table and trying to figure a way out of their dilemma. "There's nothing you can do," said my grandma. "You'll just have to tell him that you can't help with the corn this year." "Well that just doesn't sit well with me," said my grandpa. "My friend is depending on me. I can't exactly let my neighbor's harvest rot in the field, can I?" "When do you think you'd have time to do it?" she asked. "With the overtime you've been working you'd be up all night." "I know of one night that I could do it!" he said, running to the bookshelf. He grabbed the Farmer's Almanac and started flipping through the pages. "Aha! There's still one more full moon in October." They say it's called the harvest moon because it gives farmers more light and more time to collect their crops. And so a few days later, after a long shift at the factory, my grandpa made his way to the field where my grandma met him in the truck with dinner. The weather was cold but clear, and the moon was brilliant. He worked through the night to keep his word. I know this story well, so sometimes, when I'm tempted to cut corners or to put off responsibilities, I think of my grandfather with his scythe cutting wide arcs of corn in the light of the harvest moon.
Question: Which was the main trouble my grandfather had in helping his friend?
Options: (A) His wife objected to his helping his friend. (B) His corn picker ran out of oil. (C) His corn picker broke down. (D) The weather was not favorable.
Asnwer: D

Article: A new Australian research indicates that children with a stutter do not suffer disadvantages at school, More than ten percent of children have a stutter by the age of four but they score just as high as other children on tests designed to judge their language, thinking skills and character. Professor Reilly's team studied over 1600 children from Melbourne, Australia. Their mothers had been filling out regular questionnaires since their babies were eight months old and the children were judged by a range of language and behaviour tests when they reached the age of four. Reilly and her colleagues asked the parents to call the study group if their children started showing signs of stuttering. Diagnoses were confirmed by a researcher, who then visited the homes of children with a stutter every month to check on their progress. By the age of four, 181 of the children studied had been diagnosed with a stutter. Follow-up visits to the 181 children who were judged after diagnoses showed just nine no longer had a stutter one year later. Stuttering children scored 5. 5 points higher than that of their non-stuttering children on language tests and 2. 6 points higher on the test of non-verbal intelligence. The researchers said it was possible that stuttering could improve language skills, or that stuttering could result from very fast language development among some children. The research suggests parents of children who stutter are usually advised to wait a year before looking for treatment --which can be expensive -- to see if the stutter goes away by itself, unless the children become very unhappy or stop talking.
