The application of a new method for analyzing the chemistry of tooth enamel allows scientists to examine molars of prehuman ancestors and determining that their diets were more varied than had been supposed.
正确答案是E。
(E) Applying a new method for analyzing the chemistry of tooth enamel, scientists have examined molars of prehuman ancestors and determined.
其他选项也知道怎么错的,只是对这正确答案有些不解。
这里determined前面是省略了一个have吗?如果是省略了的话,为什么从句that里面是过去时(their diet were)
如果没有省略have,那and连接的两个句子时态就不一致了(have examined---and determine
不明白啊 ,求等大神来解释,
