连词or并列的成分分析
He points out that none of the conventional explantions for the rise in unwed motherhood such as the lack of jobs for inner-city males or the spread of welfare benefits explains why illegitimacy has also mushroomed among middle-class whites.
他指出，没有哪个传统解释可以说明未婚先孕母亲现象的加剧，比如城里的男人没有工作，福利的增加用来解释为什么白人中产家庭的私生现象增长迅猛。
老师，翻译前边是不能解释，后面是用来解释，而且or后面是个完整的句子，跟他并列的成分是哪个呢？谢谢老师。

He points out that none of the conventional explanations for the rise in unwed motherhood such as the lack of jobs for inner-city males or the spread of welfare benefits
explains why illegitimacy has also mushroomed among middle-class whites.
划线部分为that 从句的主语，explains为谓语，why从句为宾语从句。
粗体部分为such as A or B 结构，修饰explanations.

您好，网友。我也是英语学习者，试着回答您的问题。
理解本句的关键是理清两个关系：
1. explantions for the rise in unwed motherhood
2. explantions such as the lack of jobs for inner-city males or the spread of welfare benefits (简化such as A or B，由or连接)
看明白上面的关系之后，1和2合并，就变成
explantions for the rise in unwed motherhood such as the lack of jobs for inner-city males or the spread of welfare benefits 这样的结构了。
希望对您有用。
