Which should I choose and why:
e.g. There is/are 5 minutes left.
Well I think that when we want to refer to individual minutes the 'are' choice is better and when we refer to a period of time the 'is' choice will do, but I am not sure about this.
What about if we say "a few hours of Photoshop work" the verb should be singular or plural?
e.g. "A few hours of Photoshop work are/is hard work."
