71.Unliketheoriginal 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 activatesthe animated functions of the piece.
D.exhibit and thereby activate D是正确答案 说activate前省略了to 我倒可以理解，但是总觉得这样很奇怪啊，难保下次遇到更复杂的情况不会再错。。。 这个是不是就类似于to do A,do B,and do C这个结构？
