请帮忙分析这段句子结构,为什么用has to do with?

has to do with在这里等于has something to do with,意思是 “和...有关”,在此句中作谓语.
此句主语是the stirring of this intense debate,宾语是并列的两个从句what does it mean to be a successful parent and what does it mean to be a successful child.不过这两个从句的句序好像有误,正常情况应该是陈述句顺序,即what it means to be a successful parent and what it means to be a successful child.
大概可以译为：
做一个成功的家长意味着什么?做一个成功的孩子又意味着什么?这场激烈的辩论之所以能够产生,大概与此有关.
