(E) The question of whether the rural migrant worker is better off materially than the urban working poor is irrelevant in an assessment of the problems that they face.
本题答案是D。我们说只要开始不是动作，就不存在动作发出者问题。所以in an assessment of ...  和后面the question of 不冲突。

但prep07上。
（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.

(A) The application of a new method for analyzing the chemistry of tooth enamel allows scientists to
examine molars of prehuman ancestors and determining
(B) Through the application of a new method for analyzing the chemistry of tooth enamel, the
molars of prehuman ancestors were examined by scientists who determined
(C) When they applied a new method for analyzing the chemistry of tooth enamel, scientists
examined molars of prehuman ancestors, determining
(D) Applying a new method for analyzing the chemistry of tooth enamel, the molars of prehuman
ancestors have been examined by scientists, who determined
(E) Applying a new method for analyzing the chemistry of tooth enamel, scientists have examined
molars of prehuman ancestors and determined
本题选E。  答案说B中开始through the application of ..  和后面的the molars 冲突了。但application不是名词了。我们不是说名字不用管主句的逻辑主语吗？本题和第一题有矛盾。
还有E中时态是不是有问题。我们说and连接的两个句子时态最好一样。  E中and 前用完成时  and后用过去时，这样也有问题呀？？？？
  还有请问本题B选项到底错在了那里？？？？

不是很清楚through的用法是否正确，但是B还有其他flaw可以提供排除的依据。
their指代scientists

对于第一题：
prep07上面说道 B中molars 不是through 的逻辑主语。

对于第二题. E 中一个是完成时代，一个是过去时态是有问题的呀？完成时态可以和现在时态连用。不能和过去时态连用。除非E中determined 前面省略了have 你是怎么看这一问题的？

你分析their指代scientists的依据是就近指代，但their是未划线部分，不能认为是错的。
