Hi teachers! can anyone help me out?

Somehow the efforts and affection you have given to someone has/have been part of their daily lives.

Which one is correct here?


I would say this:

Somehow, the affection you have given and the efforts you have put in for someone have been part of their everyday life.

It is have because it is a compound subject: affection and effort

(But, I don't understand what you mean by

"have been a part of their daily life")
