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

Read the following article and select the best answer. Article: Left unfettered , Anthony Konieczka, 9 years old, would happily play his Game Boy Advance or PlayStation 2 from the minute he gets up to the moment he goes to bed, 14 bleary-eyed hours later. Anthony's box is stocked with traditional toys--board games, puzzles, art supplies--and as far as he is concerned, they are relics of Christmases past. His sister Michaely, 6 years old, still likes dressing her Barbies. But once she starts playing Game Boy, it's hard to get her away. Play patterns like this could take up another Christmas for the toy department. Through September, toy sales were down 5% compared with the first nine months of last year, according to the NDP Group. Meanwhile, the video-game industry is heading for another record year. Thanks to hot new games like Halo 2 for the Xbox, the industry is light-years ahead of the toy business when it comes out. While some new toys emerge every holiday season, toymakers are heading into this one without a monster hit . Indeed, there has not been a Furby-style frenzy in years. Of 10 toy segments only two, arts and crafts and dolls, have generated sales growth over a recent 12-month period. Some of the weakest categories like construction sets and action figures are the ones aimed at boys, who suffer the most from the video games. Analysts expect one of the top stocking stuffers this season to be not a traditional toy but the new generation of Nintendo's Game Boy, the DS, which hit stores last week. The deeper issue is that shifts in play patterns are forcing toymakers to fight for shelf space in a tightening market. Boys in particular seem to be abandoning traditional toys at earlier ages in favor of consumer electronics, video games, PC software and the Internet. The fact that kids are growing more tech-savvy , a trend called "age compression ", has troubled toy companies for at least a decade. Action figures, for instance, used to be considered healthy for boys up to age 12. Now the items are mainly marketed to boys 4 to 6. A recent study found that... Question: The sales of construction sets are decreasing because . - they are not healthy toys for children - they are very weak and easily broken - they are hard to find on shelves of toy stores - they are aimed at boys who are easily attracted by the video games
(Answer)
they are aimed at boys who are easily attracted by the video games

Ques:Read the following article and select the best answer. Article: Most people are afraid of bees. Anyone who's been stung by one quickly learns to avoid bees whenever possible. I learned that lesson when, as a child, I ran into a beehive. Dozens of bees attacked, stinging me all over my body. It was a painful incident, but I was lucky. Those bees weren't Africanized, or "killer" bees. Killer bees are extremely aggressive . When they become upset, they attack. And just about anything like noises, shiny objects, dark clothes can all cause killer bees to attack. When one killer bee stings a victim, it gives off a chemical. Other bees smell this and go into attack mode. The whole hive will aggressively attack the unfortunate victim. Killer bees will also run their victims for up to a quarter of a mile. Some victims have tried to keep away from the bees by jumping into water. But killer bees will wait for them to come up and then continue their attack. Killer bees can be found in South America and the southern prefix = st1 /United States. They were created when, in 1956, scientists brought African bees toBrazil. African bees were known to increase coffee production. Some scientists thought that these bees might increase honey production, too. So inBrazil, they tried crossbreeding the African bees with European honeybees. The results were _ The new Africanized bees actually decreased honey production and were very aggressive. Scientists tried to separate the bees, but some of them escaped and began rapidly spreading north. Since then, killer bees have been causing damage to humans, animals and the American honey industry. Over the years, these aggressive killer bees have caused nearly 10,000 people to die. What's the best thing to do if you are attacked by killer bees? Fortunately, killer bees don't fly very fast. Most healthy adults can outrun them. Experts advise you to cover your face and run! Question: Which of the following statements is true according to the passage? - It's a better way to jump into water to escape the attack of killer bees. - The Africanized bees did actually increase honey production though aggressive. - Killer bees didn't attack humans, but animals. - It is usually not easy for a killer bee to catch up with a healthy adult.

Ans:
It is usually not easy for a killer bee to catch up with a healthy adult.
