I'm little confused. According to the rule when you use and in a sentence , a verb should plural. But sometimes you use a singular verb.
Living and studying in my country was difficult. or
She thinks that the increasing computer lab hours and hiring new staff is a good idea.
Could you please explain it to me.
Thanks in advance
A more illustrative sentence might be, "Learning French and German together is difficult." It's more apparent here that 'are' is wrong.
In the second example, there is only one good idea - increasing lab hours and hiring new staff. Again, either factor by itself might not be a good idea. The good idea is doing both.
