Q: Write a multi-choice question for the following article, with the given choices and answer: Article: 1.2 million road deaths worldwide occur each year, plus a further 50 million injuries. Toreduce car crash rate, much research now is focused on safety and new fuelsthough some electric vehicle and biofuel research aims at going faster. Traveling at speed has always been risky. One cutting edge area of research in motoring safety is the use of digital in-car assistants. They can ensure you don't miss key road signs or fall asleep. The use of artificial intelligence software allows these assistants to monitor your driving and makes sure your phone or radio doesn't distract you at a vital moment. Most crashes result from human and not mechanical faulfs. Some safety developments aim to improve your vision. Radar can spot obstacles in fog, while other technology "sees through" high-sided vehicles blocking your view. And improvements to seat belts, pedal controls and tyres are making driving smoother and safer. The color1 of a car has been found to be linked with safety, as have, less surprisingly, size and shape. And alternatives to fossil-fuel based petrol, such as plant oils, are a hot area of research. Fuel cells based on hydrogen burn cleanly, and are the subject of a serious research effort. But whatever is in the fuel tank,you don't want a thief in the driving seat and there have been many innovations ,some using satellite tracking and remote communications, to fight against car theft. These communication systems can also come into play if you crash, automatically calling for help. Accidents cause many traffic jams, but there are slighter interplays between vehicles that can cause jams even on a clear but busy road, such jams can be analyzed using statistical tools. Robotic drivers could be programmed to make traffic flow smoothly and will perhaps one day be everyone's personal tool, but their latest efforts suggest that won't be soon. Options: A To call for help when one's car crashes. B .To track the car down when it is being stolen. C .To prevent car thieves from getting into your car. D To call for help when the car gets jammed in the traffic. Answer: B .To track the car down when it is being stolen. Question:
A: What is the most important purpose of innovations that use satellite tracking and remote communications?

Q: Write a multi-choice question for the following article, with the given choices and answer: Article: Doha, the capital of Qatar,is a city of contrasts . In a few decades it has beentransformed from a small port to an international city. Today, its skyline is shaped by rising skyscrapers, but Old Doha---though fast disappearing---can still be found. Time seems to stand still in the old quarter of the city. On the dusty streets, Indian and Pakistani men sit cross-legged outside tea shops and restaurants. At one end of the road, men queue by the doorways of crowded supermarkets to buy necessities: boxes of teabags, milk, sugar, bread and soap. The shops are dark and poorly stocked. However, only five miles away, on the other side of the city, Doha shows a completely different image. It shines brilliantly with skyscrapers, five-star hotels and noble apartment buildings. The area looks like any other modem district in the world. Qatar, a tiny gulf nation, is a country of vast local and international ambitions. At home, it has owned several international universities. Abroad, it tries to speak louder on gulf affairs. These ambitions are urged by the country's unbelievably rich reserves of fossil fuels.In December 2012, Daba was the site of Copl8 UN Climate Change Conference and in 2022,Qatar will host the World Cup. Mohammed Salim, 55, runs a hair salon in the old part of the city where he works as a hair dresser.When he came to Doha 22 years ago from Pakistan,he recalls,Doha was a quiet town with few modern buildings."At that time,Doha seemed rather small.There were no big roads or malls at all." He has noticed a drop in customers to his salon in recent years."People now tend to go to more fashionable hair salons in shopping malls.Some day this old area will be gone, and my business will probably be gone, too.I'll be sad. I love here, but things are changing.We can't ignore it." Options: A people in Doha are fashionable B the economy in Doha becomes bad C changes are happening to Old Doha D Doha used to be an undeveloped town Answer: C changes are happening to Old Doha Question:
A: The author takes the hair salon as an example to show that _ .

Q: Write a multi-choice question for the following article, with the given choices and answer: Article: Rescue workers found a family in their RV on Tuesday after 17 days in the mountains near the prefix = st1 /Oregoncoast. Peter Stivers, Marlo Hill-Stivers, their two children Sabastyan, 9, and Gabrayell, 8, and Hill-Stivers's mother and stepfather, Elbert and Becky Higginbotham, were in the vehicle. On their way home from a trip to the coast, the family got lost in the mountains at an elevation of about 3,800 feet. What's worse, they were trapped in four feet of snow. "We had fuel and food, but we were running short," said Elbert Higginbotham. "We were rationing ." When the family was reported missing, rescue teams from Oregon and Californiasearched likely routes to the coast. But with no leads and no idea where the family was heading, those conducting the unsuccessful search eventually called it off. In the evenings, Sabastyan and Gabrayell entertained the adults by reading jokes from Reader's Digest aloud. The family members survived mostly on dehydrated food . On Monday, Hill-Stivers and her husband decided to go for help. They packed a tent, wool blankets, tuna fish, honey, and hand-warmers to take into the wilderness with them. The children stayed safe in the RV with their grandparents. The couple were found the following day by a US Bureau of Land Management worker. A rescue team in a helicopter located the rest of the family. The family was driven out of the snowbound area on snow machines. Parents and children were happily reunited.

They had to worry about survival and rescue, and about keeping everyone calm. "I'm so proud of my family," said Elbert Higginbotham. "They stuck together, they didn't lose it." Options: A travel in the mountains should be avoided B when traveling, people should keep in touch with rescue teams C children can cause much trouble in travel D people should know how to save themselves when facing trouble. Answer: D people should know how to save themselves when facing trouble. Question:
A:
