Read the following article and select the best answer. Article: It happened one morning 20 years ago. A British scientist Alec Jeffrey came across DNA fingerprinting: He identified the patterns of genetic material that are unique to almost every individual. His discovery changed everything from the way we do criminal investigations to the way we decide family law. But the professor of genetics at the University of Leicester, UK, is still surprised, and a bit worried, by the power of the technology he released upon the world. The patterns within DNA are unique to each individual, except identical twins, who share the same pattern. The ability to identify these patterns has been used to convict(...) murderers and to clear people who are wrongly accused. It is also used to identify the victims of war and settle disputes over who is the father of a child. Jeffrey said he and his colleagues made the discovery by accident while tracking genetic variations . But, within six months of the discovery, genetic fingerprinting had been used in an immigration case, to prove that an African boy really was his parents' son.*In 1986, it was used for the first time in a British criminal case: It cleared one suspect after being accused of two murders and helped convict another man. DNA testing is now very common. In Britain, a national criminal database established in 1995 now contains 2.5 million DNA samples. The U.S. and Canada are developing similar systems. But there are fears about the stored DNA samples and how they could be used to harm a person's privacy. That includes a person's medical history, racial origin or psychological profile. "There is the long-term risk that people can get into these samples and start getting additional information about a person's paternity or risk of disease," Jeffrey said. DNA testing is not an unfailing proof of identity. Still, it is considered a reasonably reliable system for determining the things it is used for. Jeffrey estimates the probability of two individuals' DNA profiles matching in the most commonly used tests at one in a billion. Question: DNA samples are not popular with all the people because _ . - the government in Britain establishes a criminal database - the US and Canada develop similar systems - DNA samples can be used to harm a person's privacy - DNA testing is too expensive and dangerous now
DNA samples can be used to harm a person's privacy

(Question)
Read the following article and select the best answer. Article: So the little girl now walked on, her bare feet quite red and blue with the cold. She carried a small bundle of matches in her hand, and a good many more in her tattered dress. No one had bought any of them the live long day; no one had given her a single penny. Trembling with cold and hunger crept she on, the picture of sorrow: poor little child! The snow-flakes fell on her long, fair hair, which curled in such pretty ringlets over her shoulders; but she thought not of her own beauty, or of the cold. Lights were glimmering through every window, and the savor of roast goose reached her from several houses;it was New Year's eve, and it was of this that she thought. In a corner formed by two houses, one of which projected beyond the other. She sat down, drawing her little feet close under her, but in vain, she could not warm them. She dared not go home, she had sold no matches, earned not a single penny, and perhaps her father would beat her,besides her home was almost as cold as the street,it was an attic; and although the larger of the many chinks in the roof were stopped up with straw and rags. The wind and snow often penetrated through. Her hands were nearly dead with cold; one little match from her bundle would warm them. Perhaps, if she dared light it, she drew one out, and struck it against the wall, bravo! It was a bright, warm flame, and she held her hands over it. It was quite an illumination for that poor little girl; no, I call it rather a magic taper, _ , so beautifully blazed the fire within! The child stretched out her feet to warm them also; alas, in an instant the flame had died away, the stove disappeared, the little girl sat cold and comfortless, with the burnt match in her hand. Question: The little girl gave us an impression of being _ . - beautiful and kind - poor but imaginable - poor and pitiful - poor but lively
(Answer)
poor and pitiful

Ques: Read the following article and select the best answer. Article: High school students have always spread gossip in the halls, on the walls and on the phone. Now it's on the Internet, too. On various message boards, kids write about whom they hate, whom they think have fallen in love with each other and record other often hurtful things that may or may not be true. Sixteen-year-old Jessica remembers once when some kids at her school wrote cruel things about her on the web. "They were just making fun of me," she says. They said she's really ugly, she's this, she's that, blah-blah-blah. Jessica's 11-year-old sister, Emma, admits she's used the web to write bad things about another girl, though she regrets it now. "After a while, you may feel like, how could I have been so mean? Or, why did I do that?" she says. Experts say gossip on the Internet can be more harmful than the old fashioned kind. It lasts longer and is taken more seriously. And, unlike ugly words on the bathroom wall, there's no way to get rid of it. If your kids are victims of online gossip, Dr. Commanday suggests putting the gossip in to perspective . "Point out to them how what's being said on the screen differs from what everyone knows about you as a person," Dr. Commanday says. You can also try what worked from Emma: keep your kids off the offensive website! "When she was using it all the time, her name was there all the time. People were writing things about her," explains Patti Thrift, Emma's mother, "Since she has no longer had access to that, she's no longer a topic of conversation." Question: The purpose of the passage is to _ . - give some tips on how to prevent hurt of gossip on the Internet - list the difference between the old fashioned gossip and gossip on the Internet - advise students to keep away from the Internet - introduce different kinds of hurt students might meet with
Ans:
