请大家帮忙看看GWD上一道题答案是不是错了

Unlike the original National Museum of Science and Technology in Italy, where the models are encased in glass or operated only staff members, the Virtual Leonado Project, an online version of the museum, encourages visitos to "touch" each exhibit, ehich 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

答案选的D，但是thereby 的用法不是后边接动名词形式吗？谢谢了！

答案没错

OG12也是给答案D

虽然查下来几个词典给的一些例句后面都是加动名词的

也有一些句子是把thereby当作thus来用的

这么说起来thereby的用法貌似是要推敲下...
