单选题 Which of the following is Not true according to this passage?

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 roles themselves.
D、 People are enjoying themselves fully in modem museums.

【正确答案】 A

【答案解析】[解析] 是非题。[A]项和文中的visitors are encouraged to touch，listen, operate and experience的意义相反。discourage是encourage的反义词。而其余几项都可以在文中得到证明。
