GWD7-31

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.

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

怎么选D的啊，B哪里不可以啊

我自己觉得B选项首先读起来就不通，而且表达方式太罗索，不符合GMAT简洁的要求。

但是，我的问题是为什么D选项里面的“acitvate”不加第三人称单数的"s"呢？

Sorry,偶看花眼了，看成了错误的原句。

A：首先明白逻辑意思，exhibit作为展览讲，是不会activate sth.的，后面为画线部分的the piece肯定了这一点

B：an activation of 不简洁，而且不知道activation的逻辑主语

C：it指代不清

D：正确

E：which限制性定语从句修饰，不恰当；逻辑意思错误

C中的it为什么不可以指代the Virtual Leonardo Project？逻辑也挺合理的。
