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

答案选D。我自己理解是 “the Virtual Leonardo Project,......, encouranges visitors...... and thereby activate....." 但是如果主语是VL Project, 那后面的动词应该是activates而不是activate 啊，为什么答案选D？？有谁帮忙解答一下？谢谢！

activate应该是跟touch平行的 encourage visitors to touch.....and thereby (to) activate

因为有thereby, 所以句意蛮清楚的，可以不用把to写出来
