Many adults believe that somehow boys need friends less than girls do, in truth, though, no boy is an island; boys value their friends throughout childhood and adolescence and are happier and healthier when they have solid relationships with peers . Despite the common belief that girls are better at relationships, most boys consider their friends a very important part of their lives, and boys may actually be better at keeping friendships than girls are. A recent study of 10 to 15yearold boys and girls found that girls' friendships are actually more fragile. Girls tend to say and do hurtful things to each other more frequently than boys, and girls are more hurt by the end of a friendship. Boys are the living definition of the phrase "peer group"; they love games with rules, competition, and doing things together. Boys seem to enjoy, even need the opportunity to test themselves against others, and many lasting friendships begin in karate class or on the basketball court. Competence and skill are widely respected; being picked last for a team or left out altogether is an experience that can haunt a boy for years. As boys mature , the friendship becomes even more important, and it frequently widens to include girls. During the teen years, friends can become the most important part of a boy's life--and a part in which his parents are not included. The confusion of being a teenager leads boys to form close bonds with friends. There is the sense for many boys that a friend is someone who is "always there for me", someone he can trust. They may be partners in crime or partners in study, but the friendship of adolescent boys can run surprisingly deep. Question: The common belief of adults is that boys _ . Options: A: don't care about others as much as girls B: don't value friendship as much as girls C: have the same friendship as girls D: have healthier friendship than girls

For example, hunters may use a hunting charm . But they also use their hunting skills and knowledge of animals. The charm may give hunters the extra confidence they need to hunt even more successfully than they would without it. If they shoot a lot of game , they credit the charm for their success. Many events happen naturally without magic. Crops grow without it, and sick people get well without it.But if people use magic to bring a good harvest or to cure a patient, they may believe the magic was responsible. People also tend to forget magic's failures and to be impressed by its surface successes. They may consider magic successful if it appears to work only 10 percent of the time. Even when magic fails, people often explain the failure without doubting the power of the magic. They may say that the magician made a mistake in reciting the spell or that another magician cast a more powerful spell against the magician. Many anthropologists believe that people have faith in magic because they feel a need to believe in it. People may turn to magic to reduce their fear and uncertainty if they feel they have no control over the outcome of a situation. For example, farmers use knowledge and skill when they plant their fields. But they know that weather, insects, or diseases might ruin the crops. So farmers in some societies may also plant a charm or perform a magic rite to ensure a good harvest. Question: People believe in magic because _ . Options: A: magic powers are greater than natural powers B: magic can turn dreams into reality C: they are not sure of themselves D: magic can bring good results

As well as threatening the health of astronauts, this could influence long-distance missions into space. Larry Kramer of Texas Medical School in Houston and his colleagues carried out MRI scans on 27 NASA astronauts after they had spent an average of 108 days in space. About half of them had some problems in their optic nerve or eyeball. The changes match those seen in people with idiopathic intracranial hypertension, a rare condition in which the pressure of blood is abnormally high in the brain. People with the condition experience headaches, nausea and vision problems including blindness. In space, the changes are probably caused by living in free fall. "It is not because of the sunlight in space or the spacecraft's function," says Kramer. "One likely reason is that blood which normally pools in the legs is shifted toward the skull , raising pressure." The findings are similar to the results of a survey of 300 astronauts carried out in 2011. The damage in vision was reported by 29 percent of astronauts on short-term missions, and 60 percent on long-term missions. "If astronauts are exhibiting these changes after only 100 days in space, what will happen on a three-year flight to Mars?" asks Jason Kring, who studies human performance in extreme conditions at the Embry-Riddle Aeronautical University in Florida. "Deteriorating vision could seriously damage astronauts' ability to carry out routine mission tasks, including monitoring displays and navigating the rocky landscape of Mars," says Kring. "This possibility, combined with what we already know about how micro-gravity affects muscles and bones, paints a dark future for human space flight unless we start to develop effective measures." Kramer says that NASA has the matter in hand. In the wake of the study, all astronauts now have regular brain scans. This includes those yet to travel into space, providing a baseline from... Question: What can be inferred from the passage? Options: A: Staying for a long time in space will lead to blindness. B: Scientists' research in space will be banned soon. C: Space flight makes astronauts' bones function better. D: NASA has started to care for astronauts' eyesight.
