答案分析上写：...Finally, the nonrestrictive clause which... destroying it is correctly placed next to emission and set off from the rest of the sentence by a pair of commas.(A选项）

但是 C选项错题分析又说：relative clause introduced by which incorrectly and illogically modifies emission...


感觉有点矛盾啊。。。怎么回事。。。求真相。。。谢谢啦~

不矛盾呀。A里，which引导的非限定放在emmition后面，修饰technics(因为emmition是called引导的后定，不是中心词)。
C里，called引导的后定没有紧跟先行词，所以which不能跨越一个分裂结构指代technics，所以只能指代emmition
