Evil aliens have decided to kill everyone on Earth! Fortunately, they've given you two minutes to save as many as you can. All you have to do is name a country to save everyone in it.
I find it a bit misleading to refer to the largest cities as cities. In the context of this quiz, it would be less confusing to refer to them as "urban areas". If it was independent cities, then Espoo would be 2nd, Tampere 3rd and Vantaa 4th.
