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

Answer: D

不懂D里面这个activate 的主语是什么？

我选了A,但是GMAT 里面which 是不可以指代前面的句子的，所以不对了。

请大家帮忙分析，谢谢

The subject in D is "visitors".

如果activate 的主语是visitors, 那么activate 和 touch 是并列的动作阿，为什么不用to activate呢？

是因为有了thereby 的关系么？

I think you can use "to" also. However, many times you don't have to repeat.

give you an example:

I want you to visit the city and (to) take some pictures for me.

楼上说的很清楚了，activate 和 touch 动作的发出者都是参观者，如果理解为其它的东东是解释不清的。SC中经常省略个不定式的TO，或是助动词或是情态动词，让你误以为它不并列，其实是并列的。
