Question: Article: Years ago a John Hopkin's professor gave a group of graduate students this task: Go to the slums . Take 200 boys, between the ages of 12 and 16, and research into their background and environment. Then predict their chances for the future. The students, after consulting social statistics, talking to the boys, and compiling much data, concluded that 90 percent of the boys would spend some time in prison. Twentyfive years later another group of graduate students was given the job of testing the prediction. They went back to the same area. Some of the boys--by then men--were still there, a few had died, some had moved away, but they got in touch with 180 of the original 200. They found that only four of the group had ever been sent to prison. Why was it that these men, who had lived in a breeding place of crime, had such a surprisingly good record? The researchers were continually told: "Well, there was a teacher..." They pressed further, and found that in 75 percent of the cases it was the same woman. The researchers went to this teacher, now living in a home for retired teachers. How had she exerted this remarkable influence over that group of children? Could she give them any reason why these boys should have remembered her? "No," she said, "no I really couldn't." And then, thinking back over the years, she said amusingly, more to herself than to her questioners: "I loved those boys."
Question: What were a group of graduate students instructed to do?
Options: (A) To research into the living conditions of the poor citizens. (B) To foretell what the future might have in store for poor kids. (C) To study 200 boys in the slums between 12 to 16 and predict their future. (D) To survey the background and environment of 200 teenagers.

Answer: C

Question: Article: A new concept vehicle, Pod was introduced by Toyota and Sony at the Tokyo motor show. The car is intended as a four-wheeled friend. It aims to provide affection, sympathy and encouragement. Like a dog welcoming its master, the car sits up, wags its tail and acknowledges its owner's presence using hydraulics and a multi-coloured LED display panel across the front. While on the road, the car constantly monitors the driver's mood with pulse and sweat sensors on the joystick . Cameras focused on the eyes keep watch for any sigh of _ . If a driver appears to be losing his or her cool, Pod will display warnings, play soft music and blow cold air at the face. Drivers are shaken awake with loud music and a shaking chair. To improve driving skills, Pod uses a comparison to score drivers, offer advice and rank all Pod owners. Toyota claims that the car will eventually be able to learn its owner's likes and dislikes by monitoring passenger conversations. If the car hears a favorite song being discussed, it will download the track from the Internet and play it without being asked. It will also recommend restaurants that might suit the driver's taste and take photographs of passengers when they sound particularly happy. In keeping with the moodiness that is the car's main selling point, Pod expresses a form of road anger. If a driver brakes or swerves suddenly, the LED panel shows an angry red and the tail rises at the back. Anger is one of the car's ten "emotional states". Another is sadness --- a blue front with tear-shaped lights seemingly dropping from headlights --- which appears after a flat tire or when gas is low. "We wanted to show that the cars can be cheerful and entertaining," said Yasunori Sakamoto, part of the Toyota design team. Mr Sakamoto said Toyota has no plans to put Pod on the market. Sad, really.
Question: According to the text, Pod can _ .
Options: (A) rank the restaurant nearby (B) recommend a song to passenger (C) have a conversation with drivers (D) test the driver's driving skills

Answer: D

Question: Article: Every Sunday morning, as most people line up outside neighborhood breakfast spots, watch TV news shows, or head for church, Chloris Noelke-Olson is tuning up her fiddle . She is preparing to enjoy bluegrass music the old-fashioned way: with friends, at home, for free. " To be able to play with other people face to face and have that sort of connection, it is spiritual," Ms Noelke-Olson said of the weekly house concerts in Chicago she participates in. " It's like a good conversation with instruments---something that doesn't seem to happen much any more because everyone is chatting on their cellphones." She is among a growing group of Americans who are finding it pleasant to get away from the digital grid , at least temporarily. While there is no exact data to track how many people are forming knitting groups, hosting house concerts, or organizing family game nights, it is possible to connect the dots between the rising price of entertainment and the rising sales of board games and craft supplies. In the past two years, the prices for restaurant meals, concert tickets, and movie tickets all increased. At the same time, board games sales rose 6 percent, while total toy sales decreased 3 percent. These trends are expected to continue because of the struggling economy. Instead of equipping their homes with expensive home entertainment systems, consumers are more likely to pick up the old-fashioned way: eye-to-eye. Families are rediscovering ways to come together that have nothing to do with high technology. "People are turning inward to build an enjoyment time for family and home," said Linda Bettencourt, an interior designer in San Francisco whose customers typically live in million-dollar homes. Over the past six months, Ms Bettencourt has been hired to redesign living space to promote the kind of connectivity that doesn't involve wires. " The big game table is back," she says. "People want to sit around and see each other's face rather than facing a flat-screen TV."
Question: Why is Chloris Noelke-Olson enjoying bluegrass music the old-fashioned way?
Options: (A) Because she likes playing musical instruments. (B) Because she wants to provide free music for her friends. (C) Because she doesn't like talking on her cellphone. (D) Because she likes to form a close connection with people.

D
