[单项选择]
Museums have changed a lot. They are no longer places that people "should go" but places people enjoy. At a science museum in Canada, you can feel your hair stand on end as harmless electricity passes through your body. At the children’s museum in New York, you can play an African drum. There are no "Do Not Touch" signs in many museums in the USA.
More and more museum directors have realized that people can learn best when they become part of what they are seeing. In many science museums, visitors are encouraged to touch, listen, operate and experiment so that they can discover scientific rules for themselves.
The purpose is not only to interest the visitors, but also help them feel at home in the world of science. If people don’t understand science, they will be afraid of it; and if they are afraid of science, they will not make the best use of it.
One cause of all these changes is the increase in wealth and spare time. Ano
A. People are discouraged to become a part in what they are seeing.
B. People should go to museums to learn something.
C. People will understand science better by trying to discover the scientific rules themselves.
D. People are enjoying themselves fully in modern museums.
