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. 答案是A, that引导的是定语从句吧?既然引导定语从句,先行词是emotional reactions吧?那为啥要放在individual后面呢?在xdf听课时有A prep B clause C 如果prep B 做状语,定语从句就近指代原则规定clause C 指代A错,但这道题A答案明显不符合就近指代原则呀。。。
