the hard problem,on the another hand,is why it feels like sth to have a conscious process going on in one's head.这个句子该如何断句?

英语语音断句规则 1. 有标点的地方常是断句所在。如: John Smith, /our teacher,/ came in/ with a book in his hand. Our teacher 前后逗号隔开，

the hard problem 是主语
on the another hand 是插入语
is 是谓语
why 引导表语从句
it 是从句的主语
feels like 是从句的谓语
sth 是从句的宾语
to have a conscious process going on in one's head.
是不定式作状语

the hard problem is why it feels like sth to have a conscious process going on in one's head.
on the another hand是插入语,分析时不用管.
