Question: Teens don't understand the big fuss  . As the first generation to grow up in a wired world, they hardly know a time when computers weren't around, and they eagerly catch the chance to spend hours online, chatting with friends. So what? But researchers nationwide are increasingly worried that teens are becoming isolated  , less skillful at person-to-person relationships , and perhaps numb   to the cheatings that are so much a part of the e-mail world . "And a teen's sense of self and values may be changed in a world where personal connections can be limitless," said Sherry Turkle . Another researcher , Robert Kraut , said he's worried about the "opportunity costs"  of so much online time for youths . He found that teens who used computers, even just a few hours a week, showed increased signs of loneliness and social isolation. "Chatting online may be better than watching television , but it's worse than hanging out   with real friends," he said . Today's teens, however, don't see anything strange in the fact that the computer takes up a central place in their social lives. "School is busy and full of pressure. There's almost no time to just hang out," said Parker Rice, 17. "Talking online is just catch-up time." Teens say they feel good about what they say online or taking the time to think about a reply. Some teens admit that asking someone for a date, or breaking up, can be easier in message form, though they don't want to do so. But they insist there's no harm. Teens think that talking online can help them  _  . A) use computers properly B) improve their school work C) develop an interest in social skills D) reduce their mental pressures
Answer: D
