Q: Write a multi-choice question for the following article, with the given choices and answer: Article: Could smells affect your lifespan? Female fruit flies rid of the ability to smell food outlive their peers.The sense of smell may be linked to the cellular ageing process in many other organisms--even people.A link has recently been found between sensory experiences and lifespan in both worms and flies.For example, Scott Pletcher, a biologist at the University of Michigan, found that eliminating fruit flies' ability to smell enabled them to live nearly 20 percent longer than flies with an intact sense of smell. Pletcher's team reasoned that food smells were the ones most likely to affect ageing, as nutrition and longevity are known to be linked in many organisms.To test the idea that food odors affect lifespan, Pletcher's team eliminated flies' ability to smell carbon dioxide, which is produced by some fly foods.They left the rest of the smelling system intact. This intervention had no effect on male flies, but the females lived 30 percent longer than normal.Pletcher thinks eliminating the ability to smell CO2may deprive flies of information about food availability.This could signal to cells that food is scarce, causing processes that promote survival.Indeed, his team found that the CO2-insensitive female flies stored extra fat and that both males and females immune to CO2were more resistant to stress than normal flies.Pletcher isn't sure why the change in his fruit flies only affected the lifespan of the females, but he suggests that females may simply be more sensitive to the odor of CO2. A smell or taste that stretches lifespan in humans could be a potential preventative for age-related disease, he adds.Although in fruit flies it appears to be the smell of CO2that affects ageing, he says that an analogue in humans might be a smell or taste linked to human food--or a lack of it.Matt Kaeberlein studies ageing at the University of Washington in Seattle. He cautions that we don't know whether ageing and smell are linked in mammals.But " we definitely undergo physiological changes in response to smelling... Options: A Female flies are insensitive to CO2. B Smells could affect humans' lifespan. C The sense of smell is vital to humans' health. D Female fmit flies can live longer than male flies. Answer: B Smells could affect humans' lifespan. Question:
A: Which of the following best describes the passage as a whole?

Question: Write a multi-choice question for the following article, with the given choices and answer: Article: Kate Anderson became an accidental car thief when she went to pick up her daughter's car near an Ohio University building last week.Anderson saw the nickelgray Toyota Camry and used her daughter's key to unlock the car,start the engine and drive home. When Charlie Vansant left class a short time later,he found only an empty parking spot.He first assumed the car had been towed,but when the police couldn't find a record of it,they took a theft report. The morning after Anderson took back the car,her daughter discovered the Camry in the driveway wasn't hers.She found Vansant's name on paperwork in the glove compartment and looked up his phone number on the Website for the university. When she told Vansant the car was in her driveway,"It sounded real fishy at first,like maybe she wanted to hold the thing for ransom,"Vansant said! He eventually went to the house with a police officer,where he was reunited with his car.According to a police report,the case was closed "because of the mistaken car identity."Anderson wasn't charged. Vansant seemed to blame the car company more than the "thief"."Her key fit not only my lock,but my ignition as well--so highfive for Toyota,I guess,"he said. Toyota spokesman Bill Kwong said key technology wasn't as sophisticated as two decades ago,and there were so many ways to cut a key,making it possible for such a mixup to occur.He said the company now has a microchip embedded in the keys for 90 percent of its vehicles that allows them to start only with the correct key. Options: A was an experienced but unlucky thief B took Vansant's car away by chance C fould unlock any car with her special key D was accused of theft and put into prison Answer: B took Vansant's car away by chance Question:
Answer: We can learn from the story that Kate Anderson _ .

Question: Write a multi-choice question for the following article, with the given choices and answer: Article: Singles' Day ---- the Chinese opposite of Valentine's Day has turned into a massive online shopping event. It is a day when single people are supposed to buy themselves presents. But there are sociological reasons behind China's "celebration" of single life. And the imbalance could have big consequences for the country. There were 34 million more men than women in China in 2011. Part of that is natural - usually there are 105 boys born for every 100 girls. But the Chinese gender ratio at birth is much more obvious. It was 116 boys to 100 girls in 2012. The one child policy is largely to blame. Brought in to limit population expansion, the policy allows only one child per family. But because male children are seen as more valuable, as well as more likely to support their parents in old age, some parents choose to have a son over a daughter. The result is that large numbers of men will likely never get married. In fact, one study has predicted that by 2030, 1 in 5 Chinese men in their 30s will never have married, while another states that 94% of unmarried people in China are men. Traditionally, China has seen high levels of marriage, usually among the young. Besides, the increased education and career opportunities for women have meant that marriages are happening later. It is also traditional that women often marry men of a higher socioeconomic status than themselves. So women at the top and men at the bottom find themselves alone. One study has even suggested a link between an imbalanced gender ratio and growth in violent crime in the country. Singles' Day can't solve all the problems China's singles face. Indeed, it is possible that it is causing even more problems, as men resort to increasingly risky lines of work to increase their chances of gaining money and thus a wife. I am worried that as money starts to overcome romance, there is evidence that China's marriage market is increasingly materialistic. Options: A Their support of the government's late marriage policy. B Their higher education level and more work chances. C That they expect to enjoy their single time when young. D That there are too many excellent young men to choose from. Answer: B Their higher education level and more work chances. Question:
Answer:
What made women in China get married late?
