"X and Y is" or "X and Y are"? [closed]
Solution 1:
Both "is" and "are" are correct in your sentence.
If "doing research and inventing new things" is considered as representing a single idea, a singular verb is called for; If these are considered separate ideas, a plural verb is called for.
So it is not a question of right or wrong, strictly speaking.
But because in your case the two are closely related, I would prefer going with the "is" version myself.
