1) and连接的前后对象一定要平行
2) 分词短语在句首起状语作用,逻辑主语等于句子主语
(B) the molars作为through the application的逻辑主语,意思表达错误.应该是scientists through the
application而不是the molars through the application; who引导的非限定定语从句中their应该指代离
它最近的复数名词scientists,而从逻辑上their应该指代ancestors
C： when引导的时间状语从句强调从句和主句的动作发生的同时性；如果理解成“通过使用新的方法，科学家们检查了祖先们的磨牙”更加合适，即apply作为exam的方式状语，而非时间状语
(E) 正确;have examined…and determined…结构平行;未划线部分的their指代离它最近的复数名词
prehuman ancestors.
