Question: Read the following article and select the best answer. Article: That woman carried a new blanket over her arm. Wordlessly, she gave it to me. "Is it finished?" I asked. She shook her head. "No. It is ready," she replied. I handed her the money and took the blanket. "It is beautiful, so skillfully woven ," I said to my mother. "But what did she mean when she said it was not finished? How can it be ready if it is not finished?" "I will tell you later," my mother said, "but first I will take you to the Navajo village." We went down to the village. A group of young men were making sand pictures. We walked through the whole village, watching the different things the people were doing. It was not until that evening that my mother finally explained the Navajo woman's words. "Did you notice anything about the things the people were making?" my mother asked. "What should I have noticed?" I looked at her and asked. "Each thing the Navajo make has one small part that is not complete. The designs in their sand pictures are often not perfectly done, for example---the line of a circle may not quite close. If you look carefully at your blanket, you will probably find a stitch missing." I took the blanket off, but it looked as perfect as any design could be. Then suddenly, I noticed that sure enough a stitch was missing! "But why do the Navajo intentionally leave some tiny part unfinished?" I asked. "They believe that when anything is completed or finished, it means the end has come--it will not be perfect until then. Then too, with a circle, they believe that they must leave a pathway for the bad spirits to run away and the good spirits to come in. So, often, they do not make the line close." Question: What's the main idea of the text? - The Navajo are good at making things. - The Navajo are brave and hard-working. - A blanket tells a lot about the Navajo culture. - Skills are needed to do business with the Navajo.
Answer: A blanket tells a lot about the Navajo culture.

Question: Read the following article and select the best answer. Article: Renault's new Twizy could be the future of motoring ... or at least a big part of it. This is not some crazy future concept -- this is a real vehicle, fully electric, and on sale now. Prices for the Twizy start at PS6,690, with battery hire from PS45 a month. But is it a car? Technically no, it' s classified under UK law as something closer to a moped . A two-seater (the passenger sits behind the driver), the Twizy runs on electric power only, and is designed to cover all those little trips we do. And as 87 percent of Europe's drivers do less than 37 miles a day -- 50 per cent less than 12--there's really no need to be burning gas for that sort of journey. The Twizy is arguably the most unusual vehicle in this country. Other cars have been beautifully designed, others have been small, but no car has turned motoring on its head in quite the same way. The Twizy's batteries have a range of 62 miles, and it plugs into a standard socket like any other electrical equipment, going from flat to full power in three and a half hours. There are no full doors on the vehicle, so think of it like a covered moped with four wheels, but no noise and no need for a helmet. There's also a lower-powered type being designed, the Twizy 45, for which you don' t need a license. Seeing the Twizy in the flesh, you' re surprised by how striking it looks. Sit in it and everything feels right --just car enough to be easy, but different enough to be exciting. With the battery underneath you, the vehicle is suckered to the road, and the electric power means it accelerates with real energy up to about 50 mph. You don't feel you need any more. In the UK, the weather alone may make it a good buy, but the lack of easy access to outdoor sockets is the biggest challenge. Only time will tell if this brave move answers enough problems to find a place in our lives. Question: What will probably prevent the popularity of the Twizy? - Its low speed. - Its weak batteries. - Its limited inner space. - Its demand for outdoor sockets.
Answer: Its demand for outdoor sockets.

Question: Read the following article and select the best answer. Article: A third of Britons are overweight, states a report published in January by the Royal College of Physicians, the result of an 18-month study. About five per cent of children weigh too much, and are likely to stay that way for life; in the mid-twenties-age-long group the proportion of the middle-aged population half are overweight. Fat people risk severe health problems, says the report, including high blood pressure, breathlessness and various forms of heart disease. Smoking is particularly risky for overweight people. The safest way to lose weight is to eat cereals, bread, fruit and vegetables, and cut down on fatty meals, butter and sweet foods. Fad diets so far more than good; slimming machines that vibrate muscles have not been proved useful; saunas merely remove a little body water, and health farms, says the report ,serve as expensive holidays. Exercise is most important to health, the report emphasizes; though it doesn't necessarily reduce weight; it keeps the correct proportion of body muscle. And it isn't only for the young ; from middle age a minimum of 20 minutes of gentle physical jerks should be practiced three times a week. The report advocates several public health measures to fight the common existence of overweight in this country. They include an increase of tax on alcohol to reduce its increasing, and dangerously fattening, consumption; and the provision of more sports facilities by local authorities. Britain's doctors, the report concludes, must learn to be more sympathetic and specific in their advice to the overweight, encouraging a change in eating habits on a long-term basis and taking into account the many-often-complex-reasons why fat people are fat. Question: The passage mainly talks about _ . - the cause of Britons' overweight. - how to avoid getting overweight - Britons' overweight problem. - the relations between overweight and health problems.
Answer:
Britons' overweight problem.
