Write a multi-choice question for the following article, with the given choices and answer: Article: For grown-ups,an afternoon snooze is often easier said than done.But many of us have probably experienced just how simple it can be to catch some sleep in a gently rocking hammock .By examining brain waves in sleeping adults,researchers reported in the June 21issue of Current Biology,a Cell Press publication,that they now have evidence to explain why that is. "It is a common belief that rocking causes sleep:we fall asleep in a rocking chair soon and,since ancient times,we cradle our babies to sleep,"said Sophie Schwartz of the University of Geneva."Yet,how this works had remained a mystery.The goal of our study was made up of two parts:to test whether rocking does indeed improve sleep,and to understand how this might work at the brain level." Schwartz,Michel Muhlethaler,and their colleagues Laurence Bayer and Irina Constantinescu asked twelve adult volunteers to nap on a custom-made bed or"experimental hammock"that could either remain still or rock gently.All participants were good sleepers who didn't typically nap and did not suffer from excessive sleepiness during the day.Each participant took two 45-minute afternoon naps,one with the bed still and one with the bed in motion,while their brain activity was monitored. "We observed a faster transition to sleep in each and every subject in the swinging condition,"Muhlethaler said."Surprisingly,we also observed a dramatic boosting of certain types of sleep-related brain waves." More specifically,rocking increased the length of stage N2sleep,a form of non-rapid eye movement sleep that normally occupies about half of a good night's sleep.The rocking bed also had a lasting effect on brain activity,increasing slow brain waves and bursts of activity known as sleep spindles . Schwartz and Muhlethaler say the next step is to find out whether rocking can improve longer periods of sleep and to find out whether it may be useful for the treatment of sleep disorders,such as insomnia . Options: A The participants were divided into two groups. B The participants had some problems in falling asleep. C Twelve adults and children were invited to take part in it. D The participants'brain waves were examined during their nap. Answer: D The participants'brain waves were examined during their nap. Question:

Q: Write a multi-choice question for the following article, with the given choices and answer: Article: During the Victorian period, ordinary people started going on holidays to the seaside for the first time. When a woman entered a room, it was considered rude for a man to offer his seat to her because the cushion might still be warm. People thought that you could digest food better in the dark, so the dining room was often located in the basement. It was considered improper to look into someone's bedroom, so most bedrooms were on the second or third floor. People went to great lengths to hide their water closets from view. In some homes, they were behind a curtain or screen, in a separate part of the house or even outside. A lot of men used macassar oil to slick back their hair. In order to stop this grease from sticking to the furniture, pieces of material called antimacassars were placed over the backs of chairs.

Write a multi-choice question for the following article, with the given choices and answer: Article: Has the recent economic downturn affected your life? For many young Chinese, it has driven them to embrace a far more frugal (economical) lifestyle. Wang Hao, 24, is a prefix = st1 /Beijingoffice worker. He made a resolution in June last year to limit his weekly living expenses to 100 yuan. That's the cost of eight Big Macs inChina. "The financial crisis has taught a spending lesson to young people in China, including me," said Wang, who posted his resolution on his blog, which has drawn over 200,000 hits. As the financial crisis affects the economy, white-collar workers speak of reducing salaries. Some are unemployed. And university students are facing the worst job prospects since China's economic reform began 30 years ago. To save money, people have started to share dinners, houses, taxis and other activities with strangers they meet online. Web users post their activities on sites, such as www.Pinkewang.com and invite others to join them. Lin Xiongbo, the founder of Pinkewang, said his website saw a 100 percent increase of visitors last November after the global financial crisis broke out. People are also using websites like Lin's to share other activity ideas such as training programs, sports, and entertainments. "Sharing activities with others can save a lot of money without lowering one's quality of life," said 27-year-old Xu Li. He's a manager at a public relations firm and a long-time user of websites like Pinkewang. It was on the Internet that Xu recently found another person to take part in an English training program with him. By joining the program with another person, he and his partner received a 10 percent discount for the course, saving them more than 1,000 yuan. Young Chinese born in the 80s used to be accused of being materialistic. They favored designer clothes and the latest electronic products, and many of them spent their monthly salaries rather than saving them. They became known as the "Yueguang group". However, since the economy slowed down, this lifestyle has lost much of its charm.... Options: A Wang Hao's blog is popular because the stories in his blog are very interesting. B The financial crisis began to affect Chinese people's lives in December 2008. C Since the economic downturn, fast consumer lifestyles are less popular inChinanow. D The government has asked people to spend less money to fight the economic crisis. Answer: C Since the economic downturn, fast consumer lifestyles are less popular inChinanow. Question:
