一个很郁闷的英语句子,有两个系动词,是咋个事

1）But the only long-term answer is the evolution of a culture 这是主句.
2）in which the full rang of human needs,C like the needs for love ,a happy family life ,satisfying employment,exercising creativity ,acceptance no matter who or what one is are satisfied定语从句
a）定语从句的主语主语是the full rang of human needs,C like the needs for love ,a happy family life ,satisfying employment,exercising creativity ,acceptance no matter who or what one is,前面有几个名词并列作主语,后面的动词是are
b)要注意的是no no matter who or what one is 是一个状语；
另外,这是一句口语体的句子,所以定语从句中的主语后面的同位语部分的并列成分没有用and来连接.严格地来书,后面的are应该改为is,因为主语的中心词是range.
如果改为正规严谨的书面语,这句话就成了：
But the only long-term answer is the evolution of a culture in which the full range of human needs,such as the needs for love ,a happy family life ,satisfying employment,exercising creativity,and acceptance,no matter who or what one is,is satisfied.
最后,C是see的意思,表示“瞧,比如”等之类的意思.

acceptance no matter who or what on is 是名词性的结构，和前面的a happy family life等并列，所以后面要用be的复数形式are
还有C的意思可能得从上下文去看了
