（67）     GWD-7-Q31:

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.

1. exhibit, which thereby activates

2. exhibit, in turn an activation of

3. exhibit, and it will activate

4. exhibit and thereby activate

5. exhibit which, as a result, activates

答案给的是D

答案给的是D

可是我觉得，如果选D，需要把D的activate改为activates，大家觉得对吗？

thanks.

同意楼上，activate的主语应当是visitors

恩啊，我就是逻辑判断的，就觉得是那样。。。。。

现在又判断了一下，恩，觉得楼上两位MM说得对，明白了，谢谢
