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.
希望Tina老师帮忙解答一下B选项，这里面的in turn是什么意思呢？in turn　an activation of...能不能认为是前面的vistor touch exhibit这件事情导致了后面的activation？并且in turn在GMAT中经常会作为怎么样的考点出现呢？谢谢

文章逻辑1.传统理论：human是理性并且自私的 2.运用后面这个U Game的试验来驳斥传统理论。全文读成这样，第二段没怎么看，那么这道题是implies，是否可以用主旨做题呢？这道题目解题的逻辑是什么呢？ （同时也希望老师带着一句句分析一下文章，说明哪些句子应该读，哪些句子可以省略。）

According to the passage, Krontiris’s work differs from that of the scholars mentioned in line 12 in which of the following ways?
追问郭培月老师。您的意思是，这里面的两个trend是以前面两个极端观点为代表的一种只研究少数女性的trend嘛？可是11行的a significant trend明明说的是反对上面两个极端观点的学者们呀，因为是among这群学者的一种trend。紧接的下句也说的是站在第三种观点的这群学者们，那么第二段第一句所说的trend怎么会突然就不指代这群持第三种观点的学者了呢？而且下面的Tina 也是第三个观点的学者中的一个学者吧，她肯定是反对一二种观点的，530那道题里正确答案明确证明了这点，那么她肯定是第三个观点那派学者里的一个人呀，否则她不就自成一派变成第四派了
