问下下面的英语句子有没有语法错误 specific evidence regarding where are the locations dothe survey took place is also needed in order to assess the representativeness ofthe survey. 特别是where那一句,怎么改比较合适,为什么?
可以改为: Specific evidence regarding the locations of the survey is also needed in order to ... locations ”地点“的意思,故where(表示地点)与之重复,删除where.took place也属多余.
