這部分令我知道獨立是非常重要

原句寫法不好，應寫作

This part let me know that independence is quite important.

This part let me know how importance is independence.

This part let me know how importance is independence. 更正: This part let me know how important is independence.

This part let me knows the importance of independency.

I wonder whether I should use know or knows, but to my knowledge, I guess is knows.
pls correct me if I'm wrong
