Write a multi-choice question for the following article: Article: About a third of all common cancers in the United States, China and Britain could be prevented each year if people ate healthier food, drank less alcohol and exercised more, health experts said on Friday. Reports from the World Cancer Research Fund (WCRF) suggest that making simple lifestyle changes could prevent some 40 percent of breast cancers alone in Britain and the United States, as well as tens of thousands of stomach cancers. "Even in 2011, people are dying unnecessarily from cancers that could be prevented through keeping a healthy weight, diet, physical activity and other lifestyle factors," said a WCRF medical and scientific adviser. WCRF findings are supported by World Health Organization (WHO) reports, which say regular exercise can prevent many diseases such as cancers and heart diseases. Cancer is a leading cause of death around the world and its incidence is rising. Each year around 12.7 million people discover they have cancer and 7.6 million people die from some form of the disease. There are about 200 known types of cancer. Rachel Thompson, the WCRF's head of science, said that while the message was simple -- that not smoking, eating good food and being a healthy weight can help _ many cancers -- it was still a difficult one to get across. The WHO says adults should do at least 150 minutes of exercise a week. This could be done by walking for 30 minutes five times per week or by cycling to work every day. Peter Baldini, head of the World Lung Foundation, also called on all governments to introduce smoke-free laws and raise the price of cigarettes. Tobacco kills millions of smokers every year, and tobacco-related lung cancers also kill hundreds of thousands of people who don't smoke but have been exposed to it second-hand. "There isn't a magic bullet to cure all forms of cancer, but we have the opportunity and the duty to protect people from developing cancer wherever possible," Baldini said.

Q: Write a multi-choice question for the following article: Article: Humans are social animals. They live in groups all over the world. As these groups of people live apart from other groups, over the years and centuries they develop their own habits and ideas, which form different cultures. One important particular side of every culture is how its people deal with time. Time is not very important in nonindustrial societies. The Nuer people of East Africa, for example, do not even have a word TIME that is in agreement with the abstract thing we call time. The daily lives of the people of such nonindustrial societies are likely to be patterned around their physical needs and natural events rather than around a time schedule based on the clock. They cook and eat when they are hungry and sleep when the sun goes down. They plant crops during the growing seasons and harvest them when the crops are ripe. They measure time not by a clock or calendar ,but by saying that an event takes place before or after some other event . Frequently such a society measures day in terms of"sleeps"of longer periods in terms of"moons".Some cultures, such as the Eakinos of Greenland measure seasons according to the migration of certain animals. Some cultures which do not have a written language or keep written records have developed interesting ways of"telling time".For example, when several Australian aborigines want to plan an event for a future time, one of them places a stone on a cliff or in a tree. Each day the angle of the sun changes slightly. In a few days, the rays of the sun strike the stone in a certain way. When this happens, the people see that the agreed-upon time has arrived and the event can take place. In contrast ,exactly correct measurement of time is very important in modern, industrialized societies. This is because industrialized societies require the helpful efforts of many people in order to work. For a factory to work efficiently(well, quickly and without waste),for example, all of the workers must work at the same time. YCTherefore, they must know what time to start...
A: Question: The Australian aborgines' way of"telling time"is based on_.Options:A the change of the sun raysB the movement of the earth in relation to the sunC the position of the stoneD the position of the tree or the cliffAnswer:A

Problem: Given the question: Write a multi-choice question for the following article: Article: Showering typically sends water down the drain, but a new space-age shower could change that. The design, inspired by NASA, saves water and money. Astronauts have no choice but to recycle the water they use in space. _ This futuristic shower comes from Orbital Systems, a Swedish advanced technology company. Its CEO, Mehrdad Mahdjoubi, invented the product. "The shower of the future is a water-recycling shower, thus enabling water savings up to 90 percent, energy savings up to 80 percent, at the same time increasing comfort and hygiene. The water is being collected in the drain, it's being analyzed, purified and then pumped back up to the shower head. So what is so special about the purification technology? Well, it's based on a patented purification capsule system that makes sure that the water is always crystal clear," he explained. Mahdjoubi was inspired by a project between NASA and Sweden's Lund University to come up with designs for a mission to Mars. He adapted the closed-loop system that allows astronauts to re-use shower water again and again. The product already has been tested in Sweden, where it saved up to 100,000 liters of water over four months. Based on those results, Mahdjoubi is confident his company can distribute the shower system worldwide. "Our market is anyone who takes a shower, actually, and the biggest benefit it gives is to the market segment where the water consumption is the highest, such as bathing establishments, gyms, sports centers. Also, private households where the water consumption and the prices are high," said Mahdjoubi. The "out of this world" design has won several business and innovation
