Article: People who cannot tell all colors apart are said to be color-blind. Most color-blind people can see yellows and blues, but confuse reds with green. It is very rare for a person to be blind to all colors, but they may see everything in shades of black, white and gray. It is interesting to point out that many color-blind people don't even realize that they are color-blind, they don't know that the colors they are seeing and naming are not the actual colors that people with normal vision can see. This can be dangerous when a color-blind person confuses the red and green of a traffic light. Color blindness is thought to be inherited and although doctors have tested color blindness, there is no cure to treatment for it. Question: Up to now, doctors _ . Yes or no, is the answer "have been able to tell whether a person is color-blind or not"?
No

Article: Robots are being used for the first time in hospitals. "Robot-nurses" perform a variety of tasks such as delivering medicine, food and laboratory samples to sickrooms and taking away waste. Patients aren't treated by robots, as this is still done by medical staff. The idea is to employ robots to transport supplies between departments. "Nurses often have to break off from what they are doing to gather supplies," says Peter Seiff, who makes the robots called TUGs. Research shows any interruption in medical work can lead to errors --- a nurse may forget whether she has given medicine and may give a patient double the dose or none at all. The robots vary in size according to what job they perform, but normally take the shape of a metal box on wheels, with a box on the side containing their software. After being programmed, the robots are able to find their way around a hospital unassisted. They also contain scanning technology to create electronic pictures or a "memory" of routes on their hard drives to help them go through passages, doors and other obstacles. Each robot is also monitored at the producer's headquarters in case it runs into any difficulties. Trials show TUGs reduce the time it takes for a patient to receive medicine, and stop drugs from going missing. A study at the University of Maryland Medical Centre in the U.S. found that when three TUGs were used over the course of a year, the average length of time from the drugstore receiving a prescription to the patient receiving it dropped from 74 minutes to 30 minutes and saved nurses 6,123 hours finding medicines. It also cut the number of medicines that went missing to zero. "The biggest complaints we receive from patients is that the nurses don't spend enough time with them. Anything that frees nurses is a _ ," says Katherine Mulligan, director of nursing at the hospital, "The TUGs allow nurses to spend more time focusing on patient care. Nurse satisfaction has improved." Question: Which of the following is TRUE according to the passage? Yes or no, is the answer "Robots can help nurses save a lot of time."?
(Answer)
No

Ques: Article: The nation's largest group of pediatricians on Monday urged its members to "firmly oppose boxing for any child or adolescent." In a statement, the American Academy of Pediatrics (AAP) said thousands of boys and girls take part in the sport in North America, despite risks of serious brain and facial injuries. The group's position was approved by some experts. "There is very little one can do in order to increase the chance of having a healthy brain when you get old," said Dr. Hans Forstl, who has studied boxing injuries. " One of the best things you can do is avoid boxing." He said. According to the new statement, published in the journal Pediatrics, information from Canada shows a rise in boxing injuries over the past decade. Pat Russo, a retired police officer who runs a boxing gym in Brooklyn, New York, said injuries are rare in amateur boxing. After 26 years and training thousands of kids, he has seen just one split lip among his students. " If the gym is run properly, injuries are at an absolute minimum," Russo said. "Football is ten times more dangerous. While tennis or football might also help kids gain confidence, boxing holds a special attraction for children in poor neighborhoods, because it allows them to act tough while in trouble." Dr. Robert Cantu, a surgeon at Emerson Hospital in Concord, Massachusetts, said AAP's attitude makes sense for upper-class and middle-class kids. " Clearly boxing is safer today than it was 20 or 30 years ago, but it is still a very risky activity," he said. "For kids in poor areas, however, the situation is different," said Cantu. " The most dangerous thing for the majority of people in boxing is just where they live. They are far safer in the ring , even taking blows to the head, than they are out in the neighborhood." Question: In the text, Dr. Robert Cantu expressed his concern about _ . Yes or no, is the answer "children's security in poor neighborhood"?
Ans: Yes

Article: For several days I saw little of Mr.Rochester.In the morning he seemed much occupied with business,and in the afternoon gentlemen from the neighborhood called and sometimes stayed to dine with him.When his foot was well enough,he rode out a great deal. During this time,all my knowledge of him was limited to occasional meetings about the house,when he would sometimes pass me coldly,and sometimes bow and smile.His changes of manner did not offend me,because I saw that I had nothing to do with the cause of them. One evening,several days later,1 was invited to talk to Mr.Rochester after dinner.He was sitting in his armchair,and looked not quite so serious.There was a smile on his lips,and.his eyes were bright,probably with wine.As 1 was looking at him,he suddenly turned,and asked me,"do you think I'm handsome,Miss Eyre?'' The answer somehow slipped from my tongue before I realized it,"No,sir." "Ah,you really are unusual!" "Sir,I'm sorry.I should have said that beauty doesn't matter,or something like that." "No.You have honesty and feeling.There ale not many girls like you.But perhaps I go too fast.But I mean you're the sort of person people tell their problems and secrets to,because you're sympathetic and give them hope." It seemed he had quite a lot to talk to me.He didn't seem to like to finish the talk quickly."Don't be afraid of me,Miss Eyre."He continued."You don't relax or laugh very much.But in time you will be more natural with me,and laugh,and speak freely.You're like a bird in a cage.When you get out of the cage.You'11 fly very high.Good night."
