I'm taking a test and have to guess the right answer to the question after the article. Article: What if handheld tools know what needs to be done and were even able to guide and help inexperienced users to complete jobs that require skill? Researchers at the University of Bristol have developed and started studying a novel concept in robotics--intelligent handheld robots. Historically, handheld tools have been straight, unintelligent instruments that are _ of the context they operate in, are fully directed by the user, and therefore, lack any understanding about the task they are performing. Dr. Walterio Mayol-Cuevas and PhD student, Austin Gregg-Smith, from the University's Department of Computer Science, have been working in the design of the robot as well as in understanding how best to be with a tool that "knows and acts". Compared to other tools such as power tools that have a motor and perhaps some basic sensors , the handheld robots developed at Bristol are designed to have more degrees of freedom to allow greater independence from the instructions of the user, and importantly, understand the steps being carried out. This allows for a new level of co-operation between user and tool, such as the user providing directions and the tool performing the detailed task. Handheld robots, aim to share physical similarity with users but are neither fully independent as is a humanoid robot nor are part of the user's body. The aim with handheld robots is to develop the intuitiveness of using traditional handheld tools while adding planted intelligence and action to allow for new abilities. Dr. Mayol-Cuevas, Reader in Robotics Computer Vision and Mobile Systems, said, "There are three basic levels of autonomy we are considering: no autonomy, semi-autonomous when the robot advises the user but does not act, and fully autonomous when the robot advises and acts even by correcting or refusing to perform incorrect user actions." Question: What is the advantage of handheld robots compared to other tools? Options: A: They are more dependent on the users. B: They all have a motor and basic sensors. C: They don't need to follow the instructions at all. D: They have a new level of freedom to perform the task.

I'm taking a test and have to guess the right answer to the question after the article. Article: Oprah Winfrey, the American media queen, is undoubtedly one of the most successful women in the world. She's the host and owner ofThe Oprah Winfrey Show, which continuingly wins high ratings, and the founder of Harpo Productions, which produces her television shows and movies. Certainly Winfrey feels right these days. Early on, however, _ . She stayed with her grandmother after birth and moved to Wisconsin to live with her mother at 6, and hence began the most difficult period in her life. They lived in the low-income community and her mother showed her less attention. Her classmates came from families with more money and she couldn't participate with them in a lot of activities. The young girl had held too much anger and pain inside and she rebelled. She repeatedly ran away from home and got into various troubles. During that time, she turned heavy smoker, became addicted to alcohol and drug and was sent to a juvenile detention home at the age of 13. Fed up, Oprah's mother sent her to Tennessee to live with her father. To a large extent, this man saved Oprah's life and helped pave the way for her success. She received a full scholarship to Tennessee State University where she majored in Speech and Performing Arts. After graduation, she landed a job as a news reader at a television station, where she did not do well at first. But she did not give up; instead, she worked harder. She put in long hours and prepared carefully before going on camera. Her hard work paid off: she moved up swiftly to news reader and reporter in Baltimore and was offered her own talk show in 1977. From then on, her career began to take off. Some people are handed money at birth and are nurtured into success; other people create their own success, and Oprah Winfrey definitely belongs to the latter. "There is no such thing as failure in my life," she concluded, "Life is a marathon. I think the ones who survive in life do it by hammering at it one day at a time." Well, by doing so, she won the game. Question: Oprah Winfrey succeeded at last chiefly due to _ . Options: A: her hard childhood living with her grandmother. B: her hard work and the spirit of not giving up. C: her good performance in the juvenile detention home. D: her major in Speech and Performing Arts in college.

I'm taking a test and have to guess the right answer to the question after the article. Article: I often write about the bad state of television these days, but recently my mom told me about a story she saw on 60 Minutesthat was inspiring, educational, and entertaining for the whole family. I went to the show's website to see for myself. My mom was right. At a time when even Barbara Walters says she's really bored with celebrities interviews, this one will not disappoint. It's the story of Derek Paravicini, a 30-year-old who was born three months early, physically disabled (he can't button his own shirt), blind, and severely autistic . Yet, through total luck and coincidence, his family discovered that Derek had a remarkable musical talent when he was three. Derek can hear any musical composition one time and play it perfectly on the piano. That's right. He only has to hear it once. Even more unbelievable, his brain, like a computer, can keep many songs that he can immediately repeat when asked. But his talent isn't limited to just learning things by heart. Derek is a true musical genius and artist who plays beautifully in a wide range of styles and can make his own music. With his talent, Derek has raised millions of dollars putting on charity concerts. He also donates his time to senior centers where he acts as a human jukebox machine, taking requests from senior citizens who haven't heard their favorite songs for decades. As it turns out, Derek loves people and his extraordinary talent has been the key to unlocking his personality and social development. If you want to inspire your family, pop some popcorn and sit everyone down to watch this excellent piece of journalism. If your kids are like mine, it will cause a great family discussion about the definition of "disability" and the extraordinary ability of the human brain and spirit. It may even give you the perfect answer the next time your child says he or she "can't" do something. Now that's priceless. Who says there's nothing good on TV? Question: How does Derek help the elderly? Options: A: By buying them a jukebox machine. B: By building senior centers for them. C: By singing the old songs they ask for. D: By playing the piano to raise money for them.
