[求助]GWD7-31快考试了，答案疑惑

Austen1985

Unlike the original National Museum of Science and Technology in Italy, where the models are encased in glass or operated only by staff members, the Virtual Leonardo Project, an online version of the museum, encourages visitors to “touch” each exhibit, which thereby activates the animated functions of the piece.

 

A.      exhibit, which thereby activates

B.      exhibit, in turn an activation of

C.      exhibit, and it will activate

D.      exhibit and thereby activate

E.       exhibit which, as a result, activates

答案选D，我选的A。主语单数，未划线部分的动词也用的是单数形式，如果后面加and thereby activate, 也应该是activates才对啊，而且activate 的动作发出者按逻辑应该是exhibit。请指正。

说说陋见，此题考得是logical prediction

    

activate
的意思 to make a piece of equipment or
a process start working.

    

For example,
You can activate the system by buttons or voice recognition.

    

所以，这里activate这个动作发出者是人，即visitors, 而exhibit 是不会主动发出activate 这个动作的。

    

再者，不定式to do 并列时候，第二个to, 如果省略不影响句子意思，则可以省略。
