I'm taking a test and have to guess the right answer to the question after the article. 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 _ . Options: A: have found a way to prevent a person from getting color-blind B: have found a way to free a person from his color blindness C: have been able to tell whether a person is color-blind or not D: have made it quite clear the cause of color blindness

I'm taking a test and have to guess the right answer to the question after the article. Article: A South African farmer is receiving phone calls from his sheep after equipping them with cell phones to keep tabs on the flock amid recent livestock thefts, according to local press Wednesday. When the sheep call, it is always bad news for farmer Erard Louw of the Cape Town suburbs, as the phones around their necks are only set to switch on when the sheep start running, a sign that thieves have cut through the fences. "As they run it gives me a phone call and says 'Sheep One' or 'Sheep Two' and so on, so at least I know where to start looking because the farm is 750 hectares (1,850 acres)," Louw told the Cape Times daily. Louw attached the phone-like security device to the collars of four sheep in separate flocks after thieves sneaked in and stole 27 sheep and 13 lambs a couple of weeks ago, driving Louw to _ for ways to protect his animals. He said there was no use calling nearby police, as they were stationed too far away and in his experience they either lacked an available car or the vehicle was out of fuel or missing tyres -- also the work of thieves. According to Louw, the cell phones have already proved their worth, with one sheep-snatcher caught thanks to the device. Still, with theft attempts currently at their peak, given long winter nights and early nightfall, a few sheep-robbers managed to get away in spite of the device. "The phone did start ringing that night and I went out," he said, but added that he was too late. Question: You can most probably read this passage _ .

I'm taking a test and have to guess the right answer to the question after the article. Article: Most people call it "body language" -- the clues to the meaning that we get from gesture, facial expressions, posture -- everything that isn't spoken.Experts call it "nonverbal communication," but it means the same thing: a second source of human communication that is often more reliable to understanding what is really going on than the words themselves. Understanding body language is important to success, whether in the business world or in our personal lives.However, most of our ideas about body language are wrong, according to modern communication research. There is a belief that people with shifty eyes are probably lying.As Paul Ekman says, "When we asked people how they could tell if someone was lying, too much blinking and shifty eyes were the winners.But sometimes people act like that because they are shy.Liars pretend to be calm in order not to be caught. Ekman goes on to argue against such a wrong belief.Although this kind of body language is probably an expression of nervousness, it is not always because the person is lying.Shyness can, for example, make people shift their eyes.To understand what someone's behavior means, you have to watch them carefully. There is also a belief that when meeting someone, the more eye contact , the better.As a result people would like to make initial contact in formal situations, like a job interview, by staring fixedly at the other human.Yet Ekman points out that most of us are comfortable with eye contact lasting a few seconds, but any eye contact that is longer than that can make us nervous. In short, you must carefully consider the speaker and the speaking environment.Experts suggest that unless you know about someone's basic communication style, you will have little hope in understanding their true feelings through body language.In other words, body language carries important but not always true messages. Question: From the passage we can learn that _ . Options: A: there is no doubt that a liar has shifty eyes B: people sometimes blink because of shyness C: eye contact lasting a few seconds can make us nervous D: understanding body language is more helpful in business
