求教OG12 71 的解释

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 Lenardo Project, and online version of the museum, encourages visitors to touch each exhibit, which thereby activats the animated functions of the piece.

粗体是划线部分。

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

答案给的是d ,a,e 中都说which has no antecedent in this sentence. exhibit 不是antecedent 吗？

这个题当时做我也错了。后来想通了。得从意思上理解。

如果选的是activates,也就是说与encourages平行，那么动作发出者变成museum,意思上就不对了。（肯定不是museum activates the animated functions of the piece.）

或者像lz说的动作发出变成exhibit,不可能是exhibit去激活吧。也不合理。

所以只能和to touch 平行，即encourages visitors to touch.....and thereby (to) activate.是visitors发出activate的动作才合理。

谢谢2楼的回答 ，我看了一下A确实意思上不对 。

试着回答一下,which在ＧＭＡＴ考试中只能指代前面最近的名词,不能指代整句话(楼上问的语法是存在的,但是在Ｇ中错误,因为指代不明确).这里which只能指代exhibit,是错的,　exhibit不能activate(解释就是说没有先行词)

说which无先行词是因为exhibit不能发出activate这个动作，它在从句中作主语就不符合逻辑意思

句子想表达的意思是...鼓励参观者去触摸各个展品，继而（touch这种行为）激活functions

thereby表达了touch和activate这两个动作的关系，但activate的动作发出者依然是visitors

谢谢各位解释。现在想通了。
