PROBLEM: Article: I moved to this area seven years ago. For years I have had noisy neighbours. Ever since I moved into this flat, I've had to put up with noise during the night. I decided I'd had enough and I've been looking for a new flat since the beginning of the year. I haven't found anything till now. Every week I go to the estate agent's office, but it's the same story. "I might have something by the end of the week" he says, or, "Wait till next week. I think I might have a few flats by then." I've seen a few flats during my search, but I don't like any of them. One flat I saw has been empty for two years. "It's got a busy road on one side and a railway on the other!" I said loudly, "I want peace and quiet." Last week I visited the agent again. "I won't leave till you show me something," I said. "I've got just the flat for you." I went to see it and I was frightened. "But it's next to a cemetery!" I cried. "But you won't have noisy neighbours," my agent said. "It's exactly right for peace and quiet!"

PROBLEM: Article: She might not be paid, but Carnegie Mellon University's newest staff member does all that a typical receptionist can do: give directions, answer the phone -- and even gossip about her life. University officials revealed what it considers to be the world's first robot receptionist with a personality of her own. The blond receptionist, named "Valerie," puts on a headset and interacts with people by talking about her boss, her psychiatrist and her dream. Valerie, the roboceptionist, sits in a custom-made booth at the entrance of a computer science hall. With her ability to distinguish motion, she greets visitors as they come near. Type in a question on a keyboard and she gives directions around the Pittsburgh campus and provides visitors information about the weather. More than that, she tells stories about her life. From her booth, passers-by often can hear her talking on the phone. She recognizes when someone is in front of her and remembers their characteristics. She can change between tasks from talking on the phone to answering a question. Valerie, however, does have her limit. She is a drum-shaped mechanical device with a digitally lively face that appears on a computer display. Visitors have to type on a keyboard to communicate with her. And she understands only simple questions. Eventually her creators would like to install face recognition so people don't have to insert an identity card for her to remember them. And people won't have to type their questions on a keyboard if they can solve the problem of voice recognition in a crowded hall. Valerie will tell the story of a robot living in a human world.
Question: According to the passage we know that _ .
Options: (A) Valerie looks like a real beautiful woman (B) Valerie can do whatever a human receptionist can't (C) Visitors can have a conversation with Valerie (D) Valerie doesn't understand of the visitors' questions sometimes

SOLUTION: D

PROBLEM: Article: Just five minutes of exercise a day outdoors can improve mental health, according to a study. Researchers from the University of Essex, UK have found that as little as five minutes of a "green activity" such as walking, gardening, cycling or farming could help to improve mood and increase self-esteem . Many studies have shown that outdoor exercise can reduce the risk of mental illness and improve a sense of well-being, but the new study, led by Jules Pretty and Jo Barton, was the first to determine how much time needed to be spent on green exercise for the benefits to show. Barton and Pretty looked at data from 1,252 people of different ages, genders and mental health status taken from 10 studies in Britain. They analyzed their different outdoor activities including walking, gardening, cycling, fishing, boating, horse-riding and farming in locations such as a park, garden or nature trail . They found that the mental health changes were seen after just five minutes. With longer periods of time exercising in a green environment, the positive effects were more apparent. Looking at men and women of different ages, the researchers found the health changes were particularly strong in the young and the mentally ill. Green and blue A bigger effect was seen with exercise in an area that also contained water - such as a lake or river. "This is because historically we are drawn to water to survive and it is in our genetic make-up to be at one with nature," the researchers wrote in their report. Pretty said those who were generally inactive, or stressed, or with mental illness would probably benefit the most from "green exercise". "Employers, for example, could encourage staff in stressful workplaces to take a short walk at lunchtime in the nearest park to improve mental health." He also said exercise programs outdoors could benefit youth offenders.
Question: How is the study this article refers to different from other studies?
Options: (A) It determined the exact amount of time needed. (B) It took longer to finish the research. (C) It involved more people. (D) It was led by just two researchers.
