Article: If cars had wings, they could fly and that just might happen, beginning in 2012.The company Terrafugia, based in Woburn, Massachusetts, says it plans to deliver its carplane, the Transition, to customers by the end of 2012. " It's the next 'wow' vehicle," said Terrafugia vice president Richard Gersh."Anybody can buy a Ferrari, but as we say, Ferraris don't fly." The car plane has wings that unfold for flying-a process the company says takes one minute-and fold back up for driving. A runway is still required to take off and land. The Transition is being marketed more as a plane that drives than a car that flies, although it is both.The company has been working with FAA to meet aircraft regulations, and with the National High way Traffic Safety Administration to meet vehicle safety regulations. The company is aiming to sell the Transition to private pilots as a more convenient and cheaper way to fly.They say it saves you the trouble of trying to find another mode of transportation to get to and from airports: You drive the car to the airport and then you're good to go.When you land, you fold up the wings and hit the road.There are no expensive parking fees because you don't have to store it at an air port-you park it in the garage at home. The carplane is designed to fly primarily under 10,000 feet.It has a maximum takeoff weight of 1,430 pounds, including fuel and passengers.Terrafugia says the Transition reduces the potential for an accident by allowing pilots to drive under bad weather instead of flying into marginal conditions. The Transition's price tag: $ 194,000.But there may be additional charges for options like a radio, transponder or GPS.Another option is a fullplane parachute. "If you get into a very awful situation, it is the necessary safety option,"Gersh said. So far, the company has more than 70 0rders with deposits. "We're working very closely with them, but there are still some remaining steps, " Brown said. Question: It takes the carplane one minute to _ . Options: A: fold and- unfold its wings B: unfold wings for flying C: land in the airport D: meet flying safety regulations

Read the article and select the best answer. Article: Up to 90% of school leavers in major Asian cities are suffering from myopia ---short-sightedness, a study suggests. Researchers say the "extraordinary rise" in the problem is being caused by students working very hard in school and missing out on outdoor light. Eye experts say that you are short-sighted if your vision is blurred beyond 2m. It is often caused by an elongation of the eyeball that happens when people are young. According to the research, the problem is being caused by a combination of factors - a commitment to education and lack of outdoor light. Professor Morgan who led this study argues that many children in South East Asia spend long hours studying at school and doing their homework. This in itself puts pressure on the eyes, but exposure to between two and three hours of daylight helps maintain healthy eyes. Cultural factors also seem to play a part. Across many parts of South East Asia, children often have a lunchtime nap. According to Professor Morgan they are missing out on natural light to prevent short-sightedness. A big concern is the numbers of the students suffering from "high" myopia. One in five of these students could experience severe visual impairment and even blindness. These people are at considerable risk--sometimes people are not told about it and are just given more powerful glasses--they need to be warned about the risk and given some self-testing measures so they can get to an ophthalmologist and get some help. For decades, researchers believed there was a strong genetic component to the condition. But this study strongly suggests an alternative view. "Any type of simple genetic explanation just doesn't fit with that speed of change; gene pools just don't change in two generations. Whether it's a purely environmental effect or an environmental effect playing a sensitive genome, it really doesn't matter, the thing that's changed is not the gene pool---it's the environment." Question: As is mentioned above, which factor mainly results in students' myopia in South East Asia? Options: A: Genetic faults of the people. B: Elongation of the eyeball. C: The shortage of outdoor light. D: Lack of research into the problem.
