一道OG语法题

欧洋彤

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
   这题选D    OG 里说A 的which 没有先行词，exhibit不是么，不看对错，which不是可以修饰exhibit么？谢谢牛人解答

同握手，我这道题也错了。但是仔细想想，应该是visitors的行为activatesXXX才对，而exhibit这个名词是不会activatesXXXX的。而用which的话在语法上应该就近修饰exhibit，就变成exhibit刺激xxx了，但是显然在逻辑上行不通，因该是visitors的行为刺激XXX才对。至于这里and做什么用，请大牛解答，应该不是并列吧？难道是表结果？

and 是连接to touch 和 activate 的，to 升省了。activat的动作应该是visitor, 可是og 里说A 的which 没有先行词是什么意思？不看意思，exhibit 不是先行词么？

楼主翻译一下意思就知道了，要是选择A的话，逻辑是不合理的
是exhibit  activates 还是the Virtual Leonardo Project呢，
句子结构  unlike A........,where....., B, 同位语，encourages... and actives.......   多顺

which当然不能修饰exhibit啦~~~ 哪有展览品自己activates的啊~~ 是人touch的这个动作activates了~   但是which又不能指代句子，所以错了呗~~ 希望对楼主有所帮助 加油哦~
