Read the following article and select the best answer. Article: Washington: A research conducted at the University of Maryland looks at the numerous complex reasons as to why young children decide to include or exclude other kids from their group of friends. It suggests that the kids' decision-making process is much more complex than previously believed. "They take into account group information, ranging from cliques and networks, when deciding what makes a group work well. Sometimes kids are excluded because they lack social skills, but a lot of time it has nothing to do with that. Instead it has to do with what we refer to as 'group membership' such as gender, race, nation, and culture," says Professor Melanie Killen, the Associate Director of the Centre for Children Relationships and Culture at Maryland, who led the 4-year project. Reporting their findings in the journal, the researcher said whatever was the reason, individuals who experienced long-term exclusion from the group of friends suffered from depression, anxiety and loneliness. The study looked at two models to define how children make decisions regarding acceptance of other kids in their group -- the individual social _ model and the inter-group social cognition model. While the former says that children's rejection occurs due to social deficits like shyness, wariness or fearfulness, the latter says that it happens because of group dynamics, prejudice and exclusion. It was also found that the age of children was also a factor that influenced their decisions regarding other kids' acceptance as friends. "With age, kids become more aware of group dynamics, conventions, customs, and rituals. With this comes a greater concern about group functioning, which can lead to exclusion which can be negative from a social justice viewpoint," says Killen. The researcher believes that her study may have many benefits, as it could provide insights into how to help when children are rejected by their peers. Question: While making friends, children exclude those of social deficit model to _ . - keep their groups purer - make their groups more socially powerful - refuse other customs and cultures - prove their groups to be strict
make their groups more socially powerful

(Question)
Read the following article and select the best answer. Article: Most people today think of sleep as one continuous period of downtime.This is not the way people used to sleep.According to researchers,in earlier times,people divided sleep by first sleeping a few hours,waking up,then going back to sleep.In the first period,you would typically sleep until midnight or shortly afterwards.Halfway through the night,you came out of first sleep,you would stay in bed and relax quietly.It was called the watching period.Then you would start to feel sleepy.so would return to bed and tall asleep again for your second sleep.This period would continue until early morning when daylight arrived.With no artificial lighting in homes,people naturally woke up early to take advantage of sunlight. Before the 18th century, people had no gas or electricity in their homes.Fire,candles,or oil lamps were the common forms of lighting.This lack of artificial lighting in homes contributed to people's sleep patterns.It made sense for people to go to bed early. Today,human may consider divided sleep a strange habit,but sleep researchers say that it is actually a more natural sleep pattern.Dr.Thomas Wehr of the U.S.National Institute of Mental Health has studied human sleep.He thinks that modern sleep problems occur because the older, natural way of sleep is breaking through the more recent continuous sleep pattern.Wehr and other scientists believe that artificial lighting has altered the way people sleep.In a research study,he asked 15 adults to rest and sleep in darkness for 14 hours(from 6:00 P.M.to 8:00 A.M.).At first,the subjects took a few hours to get to sleep,and then slept 11 hours a night.Then overtime,they switched to divided sleep.They fell asleep for about three to five hours in the evening,stay awake for an hour or two,and then slept again for four hours till early morning. We modern humans generally do not practice divided sleep.However, many of us have the experience of waking up in the middle of the night.We usually consider this a sleeping"problem".but perhaps we should look at it as...
