Article: Hong Kong (CNN)--A Dutch artist and designer has come up with a device he hopes will suck pollutants from Beijing's smog-covered skies, creating columns of clean air for residents. An electromagnetic field caused by copper coils will pull small pieces in the smog to the ground where they can be easily cleaned. "It's like when you have a balloon which has electricity and your hair goes toward it.Same with the smog," says artist Daan Roosegaarde.His studio has reached an agreement with the Beijing government to test the technology in one of the capital's parks.With its skies regularly covered by filthy gray smog, Beijing this week announced a series of emergency measures to deal with the problem in public. Roosegaarde says an indoor experiment has already proved it works and he is confident the results--with the help of a team of scientists and engineers--can be copied outside."Beijing is quite good because the smog is quite low. It's in a valley so there's not so much wind.It's a good environment to explore this kind of thing.We'll be able to purify the air and the challenge is to get rid of the smog so you can see the sun again." Roosegaarde acknowledges that projects like this are a way of drawing attention to the problem, rather than a complete solution to Beijing's serious and terrible air pollution."This is not the real answer for smog.The real answer has to do with clean cars, different industry and different lifestyles," he says. However, he hopes the project will make a difference by allowing the city's residents to realize the difference between breathing clean and smog-filled air."I want to take a park in Beijing, 50m by 50m square, and make it the cleanest park in Beijing," he says.He is still discussing with local authorities which park will be used. Roosegaarde's studio has worked on several projects that use static electricity in unusual ways:creating a road that charges electric cars and a floor that generates electricity when danced on. Question: Roosegaarde's device . Yes or no, is the answer "can purify the polluted air"?

No

Ques: Article: How Women Were Freed From Their Homes As late as 1800, a woman's only place was in her home. Women in business were unheard of. No respectable woman would dream of entering what was strictly a "man's world". Even if she would, what could she do? Men were sure that no woman could do a job well outside her home. This was a widely-accepted idea. When the famous Bronte sisters began writing books in 1846, they had to resort to using men's names as aliases. Teaching was the first profession opened to women, soon after 1800. But even that was not easy for women to take because most high schools and colleges were open only to men. Oberlin College in Ohio was the first college in America to take in women. Nursing was regarded as a respectable profession for women only after Florence Nightingale won high credit for her nursing career and became famous. Miss Nightingale opened the first training school for nursing in 1860 in England. The invention of typewriters in 1867 helped to bring women out of their homes to join the business world. Because women are careful and have nimble fingers, businessmen found that they were well suited to this kind of work. By 1890, tens of thousands of women were working in schools, hospitals, shops, offices, and factories both in England and the States. Some even managed to become doctors or lawyers. The idea of women working in business and other circles was accepted. Question: It can be inferred from the text that besides nursing, Florence Nightingale was also _ . Yes or no, is the answer "a teacher"?
Ans: No

Article: One day a student was taking a walk with his teacher. As they went along, they saw a pair of old shoes lying in the path. They were a poor farmer's, who was working in the nearby field. The student turned to the teacher, saying: "we will hide his shoes, and hide ourselves behind those trees, and wait to see what he will do." "My young friend," answered the teacher, "we should never make fun of the poor. Why not put a coin in each shoe, and then we will hide ourselves and watch?" The student did so and they both hid themselves behind the trees. The poor man soon finished his work, and came across the field to the path where he had left his coat and shoes. After putting on his coat, he put his foot into one of his shoes, and felt something hard. Then he bent down to feel what it was, and found the coin. Surprised, he looked at the coin, turned it around and looked at it again. He then looked around, but no person was seen. He put the money into his pocket, and continued to put on the other shoe. His surprise was doubled on finding the other coin. He couldn't control his feelings and fell to his knees, looked up to the sky and expressed his thanks. Then he spoke of his wife, sick and helpless, and his children without bread. He said the help would save them from dying. The student stood there deeply moved, and his eyes filled with tears. "Now," said the teacher, "are you not much happier than if you had hidden the shoes?" Question: When the student saw the shoes, he wanted to _ . Yes or no, is the answer "play a joke on the owner"?
No
