126. The use of lie detectors is based on the assumption that lying produces emotional reactions in an individual that, in turn, create unconscious physiological responses.
(A) that, in turn, create unconscious physiological responses
(B) that creates unconscious physiological responses in turn
(C) creating, in turn, unconscious physiological responses
(D) to create, in turn, physiological responses that are unconscious
(E) who creates unconscious physiological responses in turn

答案中在解释C选项时说，This construction is less successful at clarifying the chain of events because creating seems to refer back to lying, if used as a participial, creating would have to be preceded by a comma.这一点我有两点疑问：第一，分词，特别是现在分词，在做修饰成分时，除了与逻辑主语的主动被动关系之外，还有没有什么规则？比如，曼哈顿上说分词不需要紧随修饰对象，但是OG中有些题的答案却说分词修饰的主体不明确，像是这里 creating seems to refer back to lying，我在做题的时候经常是在把选项排除到最后两个的时候，具体看分词和从句的时候经常错，感觉找不到一个什么统一的规律；第二，用逗号把主句和分词隔开具体是为了什么？有没有逗号的主要区别是不是限定和非限定呢？分词在句首我觉得还好，放在句末就很难说清楚到底是修饰什么了，看OG答案好像也是一会儿解释正确一会儿又说修饰对象不明确。
