Read the article and select the best answer. Article: The days of a pain-free visit to the dentist may not be far off. This is thanks to a little Japanese woman in a pink sweater, named Simroid. With a limited vocabulary, Simroid, the 160cm-tall robot is happy to feel your pain. Simroid is designed to be used at medical colleges. She has realistic looking skin, eyes, and a mouth fitted with replica teeth. Her chest also rises and falls as if she is breathing. Simroid releases a clear "ouch!" whenever a trainee dentist presses her teeth too hard with a tool. And she gives a reassuring "that's better" when the drill hits the right place. "We want to use the robots to train dentists to worry about whether patients are comfortable, and not just focus on medical techniques," said Naotake Shubui, a professor at Nippon Dental University inprefix = st1 /Japanwho helped develop Simroid. The robot was one of hundreds of cutting-edge devices on display at the world's biggest robot exhibition last week inJapan. As scientists improve the design of robots, they could soon be serving tea to office workers or directing shoppers. Today's robots look and act much like the humans who invented them. InJapan, robots can already be found working as home helps, office receptionists and security guards, as well as on the factory floor. There were more than 370,000 industrial robots in use inJapanin 2005, according to a report by Macquarie bank,40 percent of the world total, with 32 robots for every 1,000 workers. The economy ministry believes that the Japanese robot market will be worth more than $52 billion by 2025. Human work is being helped, and even replaced, by mechanical efficiency in almost every area, from golf-bag carriers to public toilet cleaners. But many scientists believe the age of the service robot is not far off. It will arrive once machines are capable of connecting with humans on an emotional level. Judging by theTokyoexhibition, _ has already begun. Question: Simroid is designed to _ . Options: A: aid dental trainees to focus on their medical techniques B: train dentists to be able to share patients' feelings C: help patients relax during dental surgery D: serve as the dentists' assistance during dental surgery

Article: If you want to know how crazy people can be about their pets, you might remember that Helmsley left $12 million to her little Maltese dog when she died last year. The dog's name is Trouble. And apparendy Trouble is still alive. Of course, I would hang on,too, if someone left me $12 million. Look! Top-shelf dog food, soft pillows everywhere, drivers walking me in nice leafy parks. I would live to be 110 in dog years. The dog's story is still fresh in my mind the other night when I leave a steak house after a superb meal. Then I notice a woman carrying a small bag out of the door behind me. Once outside, she walks over to where a man is holding a tiny dog hke it's a baby. The dog looks like a Maltese, too, barking and annoying, with a cute haircut, And now I am treated to an absolute astonishing sight. Because now the woman reaches into the bag and begins pulling out little pieces of meat, which she puts on a plastic spoon and feeds to the dog. This is no cheap steak house. It's actually, way out of my league --I'm there only because it's a special occasion. I can tell you this: if I walked out of the place with any leftover steak, it sure wouldn't go to a dog. Not at those prices. So now the woman is Spoon-feeding the dog and the man is just standing there, holding this dog and looking as if this is the most normal thing in the world. And the dog is calmly chewing these pieces of steak as if he's a little king. And this dog is in no hurry. He's having a great time. A few minutes go by, and now the dog finishes all of his steak. At this point, I hear the woman say to the man "Think he's still hungry?" And she glances behind her at the restaurant, as if she might go back in there to get more steak for the dog. Watching all this, I'm afraid I'm going to shout, "Are you out of your mind? Feeding all that pricey steak to that little dog? Did you see what our American life is like today? We're all going to be eating dog food if this keeps up!" Question: Seeing the dog.is being treated to expensive steak, the author becomes extremely _ Options: A: indifferent B: annoyed C: concerned D: envious
