Ques: Article: Clean your ears, because airport security might soon be scanning them. According to a recent discovery, the shape of ears could provide a reliable new way of identifying people at airports. Researchers discovered that ears of each person have a unique shape and they have created a system that can scan them. The ear scanning technique uses a technology called image ray transform that highlights all the tubular structures of the ear and measures them. Professor Mark Nixon, a computer scientist who led the team from the University of Southampton, believes ear scanning could take place as passengers walk through security gates, for example, by placing cameras on either side to record an image of their ears. Comparing the results against a database of ear shapes, the new system could help airport security workers instantly identify passengers. Nixon and his team tested 252 images of different ears and found the system was able to match each ear to a separate image held in its database with 99 percent accuracy. Besides ear scanning, there have been other systems developed for identity recognition. "With facial recognition, the systems are often confused by crows feet and other signs of ageing," Nixon said. "Your ears, however, age very gracefully. They grow proportionally and your lobe gets a bit larger, but otherwise your ears are fully formed from birth." What's more, facial recognition software is often confused by changes in expression so people need to control their faces and in some cases even avoid wearing make-up. An ear scan system would also offer a less _ alternative toretina scanning, which requires passengers to stare at scanners from a close range. Fingertip detection has long been the most effective way of identifying someone. Nixon expects there to be a combination of different techniques that can be used at the same time to identify a person." Question: The ear scanning system would help to find out _ . Yes or no, is the answer "who you are"?
Ans: No

Ques: Article: Old Behrman was a painter who lived on the ground floor of the apartment building. For years, he had always been planning to paint a work of art, but had never yet begun it. He earned a little money by serving as a model to artists who could not pay for a professional model. He was a fierce, little, old man who protected the two young women in the studio apartment above him. Sue found Behrman in his room. In one area was a blank canvas that had been waiting twenty-five years for the first line of paint. Sue told him about Johnsy and how she feared that her friend would float away like a leaf on the old ivy vine climbing hopelessly up the outside block wall. Old Behrman was angered at such an idea. "Are there people in the world with the foolishness to die because leaves drop off a vine? Why do you let that silly business come in her brain?" "She is very sick and weak," said Sue, "and the disease has left her mind full of strange ideas." "This is not any place in which one so good as Miss Johnsy shall lie sick," yelled Behrman. "Some day I will paint a masterpiece, and we shall all go away." Johnsy was sleeping when they went upstairs. Sue pulled the shade down to cover the window. She and Behrman went into the other room. They looked out a window fearfully at the ivy vine. Then they looked at each other without speaking. A cold rain was falling, mixed with snow. The next morning, Sue awoke after an hour's sleep. She found Johnsy with wide-open eyes staring at the covered window. "Pull up the shade; I want to see," she ordered, quietly. Sue obeyed. After the beating rain and fierce wind that blew through the night, there yet stood against the wall one ivy leaf. It was the last one on the vine. It was still dark green at the center. But its edges were color1ed with the yellow. It hung bravely from the branch about seven meters above the ground. "It is the last one," said Johnsy. "I thought it would surely fail during the night. I heard the wind. It will fall today and I shall die at the same time."... Question: What was in Johnsy's mind all the time when she was very sick? Yes or no, is the answer "When the last leaf falls from the ivy vine I must go."?
Ans: No

Ques: Article: There are three separate sources of danger in supplying energy by nuclear power. First, the radioactive material must travel from its place of production to the power station. Although the power stations themselves are strongly built, the containers used for the transport of the materials are not. Normally, only two methods of transport are in use, namely road or rail. Unfortunately, both of these may have an effect on the general public, since they are sure to pass near, or even through, heavily populated areas. Second, there is the problem of waste. All nuclear power stations produce wastes that in most cases will remain radioactive for thousands of years. It is impossible to make these wastes non-radioactive, and so they must be stored in one of the inconvenient ways that scientists have invented. For example, they may be buried under the ground, or dropped into deserted mines, or sunk in the sea. However, these methods do not solve the problem, since an earthquake could easily break the containers. Third, there may occur the danger of a leak or an explosion at the power station. As with the other two dangers, this is not very likely, so it does not provide a serious objection (,) to the nuclear program. However, it can happen. Separately, these three types of dangers are not a great cause for worry. Taken together, though, the probability of disaster is extremely high. Question: Which of the following is not true? Yes or no, is the answer "It is not usual for radioactive materials to be conveyed across land."?
Ans: Yes

Ques: Article: Something that has always interested me about Abraham Lincoln is, not surprisingly, his sense of humor. As far as I can tell, he's the first American President to have one. That's because the term"sense of humor" really wasn't in common usage until the eighteen-sixties and seventies. In the eighteen-forties and fifties, it was called"the sense of the ridiculous," and didn't have the positive connotations that"sense of humor" has today. Back then, what was ridiculous was what invited ridicule . Funniness and cruelty went hand in hand. Of course, they still do a lot of arm-in-arm walking in our day as well. Lincoln's humor was very different because, for one thing, it was actually "humor"as what the word meant in his time. We don't make the distinction between "wit "and "humor"anymore; but in the nineteenth century people did. Wit was unpleasant and offensive while humor was pleasant and sympathetic. It's the difference we note now when we distinguish between "laughing with" and "laughing at". Lincoln was much more about "laughing with" than "laughing at". And when "laughing at, " it was often himself he was teasing. In the famous Lincoln-Douglas debates, when Douglas accused Lincoln of being two-faced, Lincoln replied, referencing his plain looking, "Honestly, if I were two-faced, would I be showing you this one?"And, in a way, Lincoln's face itself tells us much about his sense of humor. You can comb through thousands of photographs of politicians, soldiers, and the like from Lincoln's time and not find a single smile. True, the long exposures required for photographs of that time made smiling difficult. Yet Lincoln alone, as far as I can tell, overcame that difficulty. Interestingly, while having a sense of humor, or at least the appearance of one provided by comedy writers has become a necessary characteristic for an American President in our time, in the nineteenth century, too much humor was considered problem. And that was the case for Lincoln. A journalist covering the Lincoln-Douglas debates... Question: What might the writer think of the journalist covering the Lincoln-Douglas debates? Yes or no, is the answer "His comment accurately reflected his time"?

No
