Read the following article and select the best answer. Article: Every culture has a recognized point when a child becomes an adult, when rules must be followed and tests passed. In China, although teenagers can get their ID cards at 16, many only see themselves as an adult when they are 18. In the US, where everyone drives, the main step to the freedom of adult life is learning to drive. At 16, American teens take their driving test. When they have their license, they drive into the grown-up world. "Nobody wants to ride the cheese bus to school," said Eleanor Fulham, 17. She brought the pressure back to memory, especially from kids from wealthier families. "It's like you're not cool if you don't have a car," she said. According to recent research, 41% of 16 to 19-year-olds in the US own cars, up from 23% in 1985. Although, most of these cars are bought by parents, some teens get part-time jobs to help pay. Not all families can afford cars for their children. In cities with subways and limited parking, some teenagers don't want them. But in rich suburban areas without subways, and where bicycles are more for fun than transportation, it is strange for a teenager not to have a car. But police say 16-year-olds have almost three times more accidents than 18 and 19-year-olds. This has made many parents pause before letting their kids drive. Julie Sussman, of Virginia, decided that her son Chad, 15, will wait until he is 17 to apply for his learner's permit. Chad said he has accepted his parents' decision, although it has caused some teasing from his friends. "They say that I am unlucky," he said, "But I'd rather be alive than driving, and I don't really trust my friends on the road, either." In China, as more families get cars, more 18-year-olds learn to drive. Will this become a big step to becoming an adult? Question: The passage mainly gives information about _ . - an American culture - a cultural difference between America and China - a change in the Chinese culture - the relationship between driving and a person's development
an American culture

Read the following article and select the best answer. Article: It seems hard to watch someone yawn and not to yawn ourselves. Even reading about yawning can make you do it. Now, a new study has found why yawning has such a powerful force. Yawning when others yawn, the study suggests, is a sign of pity and a form of social connection. Kids don't develop this deeply rooted behavior until around age four, the study found. Kids with autism are less likely to catch yawns. In the most serious cases, they never do. Yawning might help doctors to see whether the children are developing rightly. The work could also lead to a better understanding of the ways that people communicate and connect. "Emotional infection seems to be a born thing that connects us together," said Molly Helt, a graduate student in psychology at the University of Connecticut. "Yawning may be part of that." Inspiration for her study came when she tried to get her own autistic son to clear his ears on an airplane. She repeatedly yawned at him, hoping he would yawn back. He never did. "The fact that autistic kids don't do it might mean they're really missing out on that emotional connection with people around them," she said. "The biggest thing people try to figure out after birth is how we become humans and understand that humans have minds that are different from others'," she added. "Autistic people never seem to understand that." Like infectious laughter and crying, scientists have found that yawning is a shared experience that promotes social connection. Helt said it could fight stress after a period of being nervous and spread a feeling of calm through a group. Question: Which of the following is NOT true about yawning? - It is natural to yawn back if people around you yawn. - Some kids are too young to yawn after others. - Yawning can be used to test children's development. - Kids with autism yawn easily when others yawn.
(Answer)
Kids with autism yawn easily when others yawn.

Read the following article and select the best answer. Article: Australian Flag Designs by Readers of the Sun-Herald We received dozens of responses after inviting readers to send in their designs for a new flag. The designs we received include: James Anthony, Drummoyne James reduces the Union Jack down in size and changes its shape to become a reminder of the British tradition rather than canceling it altogether. At the same time he suggests enlarging the stars of the Southern Cross. His design attempts to use the best of both worlds in a newly designed flag. As he says, "the British part of the Australian Flag is too big and the Australian bits are too small. When you make the stars bigger the Australian flag can look impressive." Joe Bollen, Turranmurra Joe's flag has the main elements of a risen sun, white horizon , red earth at the base and the Southern Cross. He intends to make the risen sun a special Australian symbol on the flag. He believes it represents life. The Southern Cross shows that we live in the Southern Hemisphere. Maria Ieraci, Sydney Maria deleted the Union Jack but otherwise kept the flag as is with the Southern Cross and Federation Star. She says, 'There is only one correct way to change the Australian flag" and that is "to drop the Union Jack ---- when Australia becomes a Republic", which she hopes will be before 2010. Ron Bennett, Sydney Ron recommends using the Aboriginal colors but replacing their image of the sun with the map of Australia. He says, "Australia is unique being an island continent with an instantly recognizable outline at that" and "this will leave no doubt as to which country the flag belongs." Question: The Southern Cross in some of the designs represents _ . - the spirit of the nation - the position of the country - the tradition of Britain - the expectations of the people
the position of the country
