talk about the questions加each other还是toeachother？

Question

talk about the questions 后加each other还是to each other

Answer 1

talk 是不及物动词，它不可以直接加宾语，所以＂谈论问题＂，talk about the questions。each other（互相）是相互代词，这只能作宾语，所以talk 后不可以直接接each other，要加介词to或者 with。即：talk about the questions to ( with ) each other.

Answer 2

talk about the question with each other 吧，需要用到介词

Answer 3

to each other
