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: Nixon has developed the ear scanning system while there's already the fingertip detection because _ . Yes or no, is the answer "he doesn't think one system is enough"?

Article: Jayne Fisher watched anxiously as her 17-year-old daughter Katie pulled her lamb into the Madison County Junior Livestock for sale. Katie was battling cancer. This was her first chance in months to be outdoors having fun, away from hospitals and treatments, and she had come with high hopes for earning some money for her treatment. She had _ a little on her decision to part with the lamb, but with lamb averaging two dollars a pound, Katie was looking forward to it. So the bidding(began. That's when Roger Wilson, the auctioneer , had a sudden inspiration that brought some unexpected results. "We sort of let everybody here know that Katie had a situation that wasn't too pleasant," is how he tells it. He hoped that his introduction would push the bidding up, at least a little bit. Well, the lamb sold for $11.50 a pound, but things didn't stop there. The buyer paid up, then decided to give the lamb back so that it could be sold again. That started a chain reaction, with families buying the animal and giving it back, over and over again. When local businesses started buying and returning, the earnings really began to pile up. The first sale is the only one Katie's mom remembers. After that, she was crying too hard as the crowd kept shouting, "Resell! Resell! " Katie's lamb was sold 36 times that day, and the last buyer gave it back for good. Katie ended up with more than $16,000 to pay her medical expenses----and she still got to keep her famous lamb. Question: Why did families buy Katie's lamb and return it repeatedly? Yes or no, is the answer "They wanted to help Katie from the heart"?
