Article: The oddness of life in space never quite goes away. Here are some examples. First consider something as simple as sleep. Its position presents its own challenges. The main question is whether you want your arms inside or outside the sleeping bag. If you leave your arms out, they float free in zero gravity, often giving a sleeping astronaut the look of a funny balled  dancer. "I'm an inside guy," Mike Hopkins says, who returned from a six-month tour on the International Space Station. "I like to be wrapped up." On the station, the ordinary becomes strange. The exercise bike for the American astronauts has no handlebars. It also has no seat. With no gravity, it's just as easy to pedal violently. You can watch a movie while you pedal by floating a microcomputer anywhere you want. But station residents have to be careful about staying in one place too long. Without gravity to help circulate air, the carbon dioxide you exhale   has a tendency to form an invisible  cloud around you head. You can end up with what astronauts call a carbon-dioxide headache. Leroy Chiao, 54, an American retired astronaut after four flights, describes what happens even before you float out of your seat,"Your inner ear thinks your're falling . Meanwhile your eyes are telling you you're standing straight. That can be annoying--that's why some people feel sick." Within a couple days --truly terrible days for some --astronauts' brains learn to ignore the panicky signals from the inner ear, and space sickness disappears. Space travel can be so delightful but at the same time invisibly dangerous. For instance, astronauts lose bone mass. That's why exercise is considered so vital that National Aeronautics and Space Administration (NASA) puts it right on the workday schedule. The focus on fitness is as much about science and the future as it is about keeping any individual astronauts return home, and, more importantly, how to maintain strength and fitness for the two and a half years or more that it would take to make a round-trip to Mars. Question: One of the NASA's major concerns about astronauts is   _  . Yes or no, is the answer "how they can remain healthy for long in space"?
(Answer)
No

Article: I once had my Chinese MBA students brainstorming on "two-hour business plans". I separated them into six groups and gave them an example: a restaurant chain. The more original their idea, the better, I said. Finally, five of the six groups presented plans for restaurant chains. The sixth proposed a catering service. Though I admitted the time limit had been difficult, I expressed my disappointment. My students were middle managers, financial analysts and financiers from state owned enterprises and global companies. They were not without talent or opinions, but they had been shaped by an educational system that rarely stressed or rewarded critical thinking or inventiveness. The scene I just described came in different forms during my two years' teaching at the school. Papers were often copied from the Web and the Harvard Business Review. Case study debates were written up and just memorized. Students frequently said that copying is a superior business strategy, better than inventing and creating. In China, every product you can imagine has been made and sold. But so few well developed marketing and management minds have been raised that it will be a long time before most people in the world can name a Chinese brand. With this problem in mind, partnerships with institutions like Yale and MIT have been established. And then there's the "thousand talent scheme": this new government program is intended to improve technological modernization by attracting top foreign trained scientists to the mainland with big money. But there are worries about China's research environment. It's hardly known for producing independent thinking and openness, and even big salary offers may not be attractive enough to overcome this. At last, for China, becoming a major world creator is not just about setting up partnerships with top Western universities. Nor is it about gathering a group of well-educated people and telling them to think creatively. It's about establishing a rich learning environment for young minds. It's not that simple. Question: We can infer from the passage that   _  . Yes or no, is the answer "high pay may not solve the problem of China's research environment"?
(Answer)
Yes

Article: Coffee is a powerful beverage.On a personal level,it helps keep US awake and active.On a much broader level,it has helped shape our history and continues to shape our culture. Coffee didn't take off until the l400s when people figured out they could roast its seeds.By the l500s,the drink had spread to coffeehouses across the Arab world.Within another l50 years,it took Europe by storm. "It actually had a major impact on the rise of business," historian Mark Pendergrast says.Coffeehouses became a spot not just to enjoy a cup but to exchange ideas.The insurer Lloyd's of London was founded hundreds of years ago in one of London's 2,000 coffeehouses.Literature,newspapers and even the works of great composers like Bach and Beethoven were also spawned in coffeehouses. It is often said that after the Boston Tea Party of l773,when American colonists attacked British tea ships and threw boxes of tea into the harbor,Americans universally switched over to drinking coffee.In a letter John Adams wrote to his wife,Abigail,the Founding Father claims his love of tea but says he will have to learn to embrace coffee instead,because drinking tea had become a symbol of not loving the country. For all the upsides coffee has brought the modern world,it also led to its fair share of downsides,too.Europeans carried coffee with them as they colonized various parts of the world,and this frequently meant they enslaved people in order to grow it.In Brazil -- where slavery was legal until l888 -- coffee plantations would use slash-and-burn agriculture,tearing down rain forests and planting coffee trees.Once the soil had been exhausted,growers would move on to another place. And yet,coffee,as Pendergrast says,"had a very good impact in many ways on our civilization,even though it was,for a long time,grown by slaves." Question: What is mainly talked about in this passage? Yes or no, is the answer "Important Roles that coffee played in history."?
