Q: Write a multi-choice question for the following article: Article: People hold different views on what or how much homework should be. It is partly due to the fact that people can't seem to agree on the purpose of homework. Some teachers think that homework is necessary to reinforce what is learned in school. And so they ask their students to memorize what was discussed in class through homework. Some teachers think the point of homework is to cover material that the class didn't have time to get to, so their homework is to let students learn additional things. Other teachers like homework simply because they want students to form work habits and still others believe homework is necessary because it's the best way for parents to learn what their children do in school. However, many parents seem to have different ideas. Elisa Cohen, who has twins at Lafayette Elementary School, doesn't like the fact that third-grade students in DC elementary schools are asked to write about 25 book summaries a year. She said, "They do the same thing over and over without really getting into alternate ways of thinking about books, reading and writing." Some education reformers , such as Howard Gardner, a Harvard University professor well-known for his theory on multiple intelligence, think that Cohen is on the right track. But it's often hard to persuade overworked teachers to give much thought to homework tasks.
A: Question: Some education reformers think we should improve our school education by _ .Options:A increasing homeworkB changing schoolsC changing teachersD reducing homeworkAnswer:D

Question: Write a multi-choice question for the following article: Article: The Royal Commission on Environmental Pollution has just published a report on new materials and has looked at the case of nanotechnology , which describes the science of the very small. Nanotechnology covers those man-made materials or objects that are about a thousand times smaller than the microtechnology we use, such as the silicon chips of computers. Nanotechnology gets its name from the nanometer, which is a billionth of a meter. There are about 600 consumer products already on the market that use nanotechnology. Nanomedicine is also being developed to fight cancer and other fatal diseases. The Royal Commission found no evidence of harm to health or the environment from nanomaterials, but this "absence of evidence" is not being taken as "evidence of absence". In other words, just because there are no apparent problems, this is not to say that here is no risk now or in the future. The commission is concerned about the pace at which we are inventing and adopting new nanomaterials, which could result in future problems that we are ill-equipped to understand or even find with current testing methods. One of the problems about nanotechnology is that when we make something very small out of a well known material, we may actually change the functionality of that material even if the chemical composition remains the same. Indeed, it is not the particle size that should concern us, but its functionality. Take gold, for example, which is a famously inert substance, and valuable because of it. It doesn't rust or corrode because it doesn't interact with water or oxygen. However, a particle of gold that is between 2 and 5 nanometers in diameter becomes highly reactive. This is not due to a change in chemical composition, but because of a change in the physical size of the gold particles. How can a change in size result in a change of function? One reason is to do with surface area. Nanoparticles have relatively a much bigger surface area. It is like comparing the surface area of a basketball with the total surface...
Answer: Question: Which process explains that there might be risks in nanotechnology?Options:A expand surface area -increase interactivity - change functionality-cause possible dangersB expand surface area - change functionality - increase interactivity -cause possible dangersC increase interactivity - expand surface area - change functionality-cause possible dangersD increase interactivity - change functionality - expand surface area-cause possible dangersAnswer:A

[Q]: Write a multi-choice question for the following article: 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....

Question: Write a multi-choice question for the following article: Article: An Australian inventor has designed and built an environmentally friendly ferry that uses solar and wind power to transport people around Sydney Harbor. Robert Dane and his Solar Sailor were given the top prize at the Australian Design Awards recently. The Solar Sailor has been in use for six months. It uses four sources of energy for its power -- solar, wind, battery power with stored solar energy and a fuel generator in store all controlled by computers. The ferry can travel up to 7.5 knots on just wind and solar power. It's solar wings and fiberglass solar panels which not only take in sunlight and store it in batteries, but also act as sails. "We angle our solar panels to the sun in two planes , which increases the amount of energy we get from the sun by 40 percent," Dane says. "And also we can use that same structure to do another job, which is also the sail, and so these wing sails actually push the ferry forward just like a soft sail does." Computers check the sun and wind and angle the solar wings to take in the most sunlight. If there isn't much wind or it is a cloudy day, energy stored in the batteries runs the electric motor for up to five hours. "If the batteries are too low, then the computer turns the generator on so the boat is always able to meet a commercial schedule, or get from point A to point B no matter what," Dan explains. Dane got his idea for the Solar Sailor from a book on insects. He was amazed how insects use their wings to collect solar energy to warm themselves. "When I read that, I realized there was a good example in nature for what we were going to do, which was to use a solar wing to collect solar energy and also to sail," he says.
