I'm trying to find out whether I should use a singular or plural verb when there are multiple gerunds as the subject of the sentence.
For example:
Running the correct course and keeping a steady pace are/is necessary in order to win.
With either one of these by itself, "is" would be correct:
Running the correct course is necessary in order to win.
Keeping a steady pace is necessary in order to win.
With both gerunds combined, I can't seem to figure out whether the verb should stay singular since each phrase is singular, or if it should become plural since there are two connected by "and".
If we just treat the gerunds as regular nouns, then obviously it would become "are", but I'm not sure if gerunds have the exact same rules as regular nouns.
I know that if the sentence was:
Running the correct course and keeping a steady pace are both necessary.
That "are" would be correct, but without the "both" it sounds incorrect to me.
Does anyone know the official rule here?
