1.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

B选项 OG解释 In turn an activation ... seems to be the subject of a new clause, but it has no verb, so the sentence is incomplete.
1. in turn 又不是连词，为什么后面要加完整句子不能少v？

2.Combining enormous physical strength with higher intelligence, the Neanderthals appear as equipped for facing any obstacle the environment could out in their path, but their relatively sudden disappearance during the Paleolithic era indicates that an inability to adapt to some environmental change led to their extinction.

(A) appear as equipped for facing any obstacle the environment could put in their path,
(B) appear to have been equipped to face any obstacle the environment could put in their path,
(C) appear as equipped to face any obstacle the environment could put in their paths,
(D) appeared as equipped to face any obstacle the environment could put in their paths,
(E) appeared to have been equipped for facing any obstacle the environment could put in their path,

我能理解不能用A/C/D的一般现在时，因为一般现在时暗示现在仍然 appear this way 和后文diappearance 不符
但是用have been equipped 的现在完成时，OG解释说 “The verb tense clearly indicates that the current evidence is about Neanderthals in the past."
现在完成时怎么就体现这个evidence是在过去的呢？现在完成时不是指对现在仍有影响么？这改成一般过去式可以么？

谢谢楼主提出这个问题，以前我也疑惑过，现在说说我的想法。如果单独的看exhibit, which thereby activates the... 会认为这句话很对。但是如果读一遍完整的句子“不像在意大利的博物馆，那里的模型被玻璃隔离并且只能被工作人员操作，这个网络形式的博物馆--VL计划，鼓励人们接触展览品，并且激活这些piece的生动的功能”.需要注意的是piece的理解，因为在网络上，展览品很可能是是以图片的形式出现的（设想一下，如果变成3D的肯定会更加生动吧），所以实际上是这种网络形式的博物馆计划“激活”了这些piece的生动的功能

重点是我不理解OG说B选项为什么错？【单从语法上看】 In turn an activation ... seems to be the subject of a new clause, but it has no verb, so the sentence is incomplete.

in turn 又不是连词，为什么后面要加完整句子不能少v？

对于第二个问题，首先不要想着自己去改答案，我们要做的就是在五个选项中选出最好的。have done现在完成时，可以理解为“发生在过去，直到现在还有影响”。因为N人现在也可以“看起来...”，并不是说它们以前是那样，现在就不是那样了。所以现在完成时正确。我倒是刚开始对appear的现在时态感觉有疑问，但是如果理解为"现在看起来..."应该也没问题

In turn是副词，所以后面这句其实是一个名词短语，它不仅缺谓语，还缺连词。OG中指出它没有谓语（虽然没有指出它缺少连词），这并没有问题。而且请你看看so the sentence is incomplete.“这句话”是指以activation作为主语的这句话，和前面的句子并没有关系，因为不是sentences are incomplete.

in turn是“反过来”的意思，但是按照句子的逻辑应该是递进关系，意思是触碰展品激活。。。如果用A选项的话一系列动作都连贯起来了
