Article: A recent study suggests that teens' relationship with parents, friends and teachers may have a lot to do with why they don't get a good night's sleep. David Maume, a sociologist and sleep researcher, analyzed federal health data, which interviewed 974 teenagers when they were 12, and then again at 15. He found that family dynamics have much to do with how well kids sleep. Teens, who had warm relations with their parents and felt like they could talk to them or their parents were supportive of them, tended to sleep better. However, families that were going through a divorce or a remarriage tended to affect teens' sleep. And problems at school also affected teens' sleep. Feeling safe at school and having good relations with teachers tended to promote better sleep. As did good relationships with friends. Kids who took part in sports or other positive social activities or shared similar academic goals with their friends were also more likely to get a good night's sleep. These add up to what makes lots of sense: a general feeling of well-being helps teens sleep. If we're happy and contented, we're much more likely to sleep better than if we're sad and anxious. Now, of course, teens can hardly resist being drawn to their computers and social networking. Maume also found that when parents were strict not only about bedtime, but also about limiting technology, kids slept better. It's a finding that seems obvious, but parents really do matter when it comes to health habits of their teenagers. Clearly, teenagers aren't getting 9 to 10 hours a night, which puts them at risk for all the consequences of lack of sleep, including poor academic performance, colds and stress. Question: According to Maume's analysis, who will probably have a poor night's sleep? - Teens who feel like talking with their parents. - Teens who have friends sharing their dreams. - Teens who feel contented about themselves. - Teens who lack a sense of security at school.
Teens who lack a sense of security at school.

Article: People diet to look more attractive.Fish diet to avoid being beaten up,thrown out of their social group,and getting eaten as a result.That is the fascinating conclusion of the latest research into fish behavior by a team of Australian scientists. The research team have discovered that subordinate fish voluntarily diet to avoid challenging their larger competitors."In studying gobies we noticed that only the largest two individuals,a male and female,had breeding rights within the group," explains Marian Wong."All other group members are nonbreeding females,each being 5-10% smaller than its next largest competitor.We wanted to find out how they maintain this precise size separation." The reason for the size difference was easy to see.Once a subordinate fish grows to within 5-10% of the size of its larger competitor,it causes a fight which usually ends in the smaller goby being driven away from the group.More often than not, _ is then eaten up. It appeared that the smaller fish were keeping themselves small in order to avoid challenging the boss fish.Whether they did so voluntarily,by restraining how much they ate,was not clear.The research team decided to do an experiment.They tried to fatten up some of the subordinate gobies to see what happened.To their surprise,the gobies simply refused the extra food they were offered,clearly preferring to remain small and avoid fights,over having a feast. The discovery challenges the traditional scientific view of how boss individuals keep their position in a group.Previously it was thought that large individuals simply used their weight and size to threaten their subordinates and take more of the food for themselves,so keeping their competitors small. While the habits of gobies may seem a little mysterious,Dr.Wong explains that understanding the relationships between boss and subordinate animals is important to understand how hierarchical societies remain stable. The research has proved the fact that voluntary dieting is a habit far from exclusive to humans."As yet,we... Question: The experiment showed that the smaller fish _ . - fought over a feast - preferred some extra food - challenged the boss fish - went on diet willingly
went on diet willingly
