Question: Read the following article and select the best answer. Article: My son loves video games very much. He spends hours every day playing video games in his room. Is there anyredeeming educational value to video games? Some seem like they could help him learn strategy. But I worry others may be too violent ornumb his mind. Cecilia Some games may improve kids' hand-eye coordination and problem-solving skills. Games that require kids to actually move ormanipulate the game through their own physical movement can even get _ kids moving, though not as much as they could if they actually played outside or participated in sports or other outdoor acuities. Others, though, don't have such benefits, and violent video games have been shown that they might increase kid's aggressive behavior. Like a lot of aspects of raising kids, when it comes to video games, the healthiest approach is actually self-control. The American academy of Pediatrics(AAP) recommends that kids should spend no more than 2 hours each day on screen time, including watching TV or movies, or playing computer or video games. So consider setting limits at least that strict to keep game playing from affecting their schoolwork, household responsibilities, and the physical activity your son needs very day. Make sure that he's playing games which are suitable for his age group. All video games are rated and labeled by the Entertainment Software Rating Board. Steer clear of any rated "M" for mature. Those are for ages 17 and older and can contain heavy-duty violence, strong language, and sexual content. Try to keep the video gameconsole in a common area of the house, not your son's room. That way you can catch any inappropriate content in the games he's playing, and he'll be in a position to interact with others in the house while he's playing. Make sure your son has appealing alternatives, too, such as sports, activities, opportunities to socialize with peers; and downtime to be creative. If you continue to have concerns about his video game activity, talk with your doctor. Reviewed by:Mary L.

Question: Read the following article and select the best answer. Article: When a person travels over long distances, the place may not be the only change. When his or her body rhythms get thrown off, he or she suffers from jet lag -- it's hard to sleep and eat at the right times in the new location. Humans and animals have a biological clock in their body that tells them when to sleep, and when to wake. When someone comes to a different place far away, this biological clock takes a while to match the day and night time of the new place. In a new study, reported in November's Science News, researchers at the University of California, Berkeley tested the effects of jet lag on hamsters . They wanted to know how serious jet lag would affect the brain and thinking habits of the animals. They think what happens to hamsters may happen to humans, too. In their experiments, the researchers first moved the hamsters' schedules forward by six hours. The animals' eating schedules, for example, were changed. If a hamster was often fed at noon and 4 pm, then it ate at 6 pm and 10 pm on the new schedule. People who travel from China to Europe experience the same shift, since the two regions are about six hours apart, half the shift between China and the USA. After three days, the scientists did it again - they shifted the hamsters' schedules forward by another six hours. Three days after that, they did it again; and then again three days later. For a full month, the scientists changed the hamsters' routines every three days. During the study, the hamsters slept the same amount every day as they did before the study. However, their sleep patterns had a hard time keeping up with the changing schedule. What's more, they seemed to feel low. The researchers also found that the hamsters had trouble with basic learning exercises during the study. The animals' thinking problems didn't go away when the experiment was over. A month after they went back living on a normal schedule, the hamsters still had trouble with basic mental tasks, such as learning and memory. The scientists concluded that serious...
