Please answer the following question: I'm taking a test and have to guess the right answer to the question after the article. 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: Which of the following is TRUE according to the passage? Options: A: Roosegaarde is confident of his project. B: Roosegaarde has designed an electric car. C: Roosegaarde has made an experiment in a park. D: Roosegaarde's experiment has won the support of the public.
A:
